    Hur dokumenteras blackout ombord på fartyg?: En studie av haverirapporter där blackout var en del av händelseförloppet2014Independent thesis Basic level (university diploma), 180 HE creditsStudent thesis
    Abstract [en]

    On board vessels it is not desirable to have a power failure, a so-called blackout. The thesis

    has investigated to what extent it is feasible to perform comparative and preventive studies

    with the accident reports from European flag states as a basis. This in order to investigate

    recurring shortcomings, of the vessels or in the work on board that has caused the blackout. In

    addition the possibility to categorize the cases was investigated. The categories were technical

    errors, operational errors and organization errors. Roughly half of the cases show that a single

    category of fault could not be identified due to a combination of faults leading to the blackout.

    However there are recurring cases with almost identical scenarios. For example unsatisfactory

    insulation caused fires due to leaking fuel hitting the hot surfaces.

    The survey shows that there is a lack of symmetry regarding the language used, structure,

    scope and form of publication. It also showed faults in the search engines of the databases.

    Farledsrestriktioner nu och då: Sjöfartsinspektionens övergång till Transportstyrelsen och dess effekter på arbetsprocessen bakom farledsrestriktioner2017Independent thesis Basic level (degree of Bachelor), 10 HE creditsStudent thesis
    Abstract [sv]

    En farledsrestriktion innebär att vissa krav eller begänsningar sätts på fartygs manöverförmåga, antal assisterande bogserbåtar, största djupgående och liknande egenskaper för att få färdas i en specifik farled. Innan 2009 låg uppgiften att ta fram dessa restriktioner på Sjöfartsverket och det tillhörande Sjöfartsinspektionen. År 2009 bildades Transportstyrelsen och övertog då vissa delar av processen. Detta arbete handlar om vad denna omorganisation har fått för effekter på arbetsprocessen och dess resultat utifrån vad de som idag jobbar med den upplever. En kvalitativ intervjustudie med semistrukturerade intervjuer genomfördes med ett antal individer som dagligen arbetar med denna process. Resultatet målar upp bilden av en arbetsprocess som genomgått mindre förändringar men som på många sätt fortfarande är sig lik. De tillfrågade beskriver små skillnader i det praktiska, dagliga arbetet och den kommunikation som detta arbete kräver, men beskriver också en situation där förändringsarbetet fortfarande upplevs pågå och där vanor kring arbetsrutiner på många sätt lever kvar.

    Checklista för start av ångpanna av typ cirkulerande fluidbädd via anläggningens styr- och övervakningssystem på Örtoftaverket2018Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Detta examensarbete är utfört på efterfrågan av Kraftringen AB för deras bioeldade kraftvärmeverk på Örtofta, cirka en mil utanför Lund. Projektet grundar sig i en avsaknad av lättanvänd befintlig dokumentation som beskriver kall och varmstart för deras 110 MW virvelbäddspanna tillverkad av Foster-Wheeler. Det fanns sedan pannan byggdes startmanualer, men dessa är otroligt stora, komplexa och svåranvända. Fokuset på detta examensarbete är därför att framställa en tydlig och lättanvänd startinstruktion i form av en checklista som beskriver kall och varmuppstart i en kronologisk steg för steg metod. Den slutgiltiga checklistan är utformad för att användas tillsammans med pannans användargränssnitt. För att uppnå våra mål har vi läst och sammanfattat all relevant panndokumentation samtidigt som vi har utfört en rad intervjuer av pannoperatörer och rådfrågat om deras åsikter om checklistans utformning.

    Belastningsergonomi och arbetsmiljörisker vid maskinrumsarbete på fartyg: Riskbedömning av underhållsarbete på separatorer2015Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of the study is to identify work hazards by analyzing the work activities and work environment during a separator overhaul onboard a ship. To identify risks the study used the Swedish Work Environment Authority´s regulation AFS 2012:02, the assessment form KIM 1 and a biomechanical program ALBA. The results show that there are risks for stress load on the body and that there is room for improvements. An example of an improvement is to design an additional workbench to allow proper work postures and decrease the number of lifts. The results also show the importance of using the right technique while lifting to reduce the chance of stress load. The study can be used for further studies on the work environment hazards onboard ships.

    Riskanalys av brand i avgassytem som avser dieselmotorer som opererar med låg belastning på fartyg2019Independent thesis Basic level (university diploma), 10 HE creditsStudent thesis
    Abstract [en]

    With escalating bunker costs and oversized engine installations an increasing number of vessels have started to operate in a mode known as slow steaming. This means that the soot fires in exhaust gas boilers/economizers have increased and in some extreme cases led to hydrogen fires. This thesis focus on how diesel engines use residual fuels and operate with a low engine load. The purpose of this thesis is to investigate whether incomplete combustion caused by a low combustion temperature leads to the accumulation of unburned fuel and cylinder oil in the exhaust gas system and to describe which precautions eliminate the risk of a fire in the exhaust gas boiler or exhaust gas economizer. A literature review has been conducted and data has been collected in the field of diesel engine with priority given to marine steam boilers. The result of the study shows how difficult (problematic) it is to run a diesel engine at a lower power output, since the vessel often is designed for a heavy fuel oil operation when the engine load approximately 80 % output.                      Conclusions from the study show that even when a faultless engine has not reached operating temperature, incomplete combustion of fuel and lubricating oil occurs due to the low temperature in the combustion chamber. This can entail operational risks by accumulating unburned fuel and cylinder oil in exhaust systems such as wet and sticky carbon deposit. The result shows that water washing, steam cleaning and catalytic cleaning are the most efficient cleaning methods for most deposits in exhaust gas boilers and economizers.

    Vad krävs för att genomföra en säker livbåtsövning?2017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Frequent abandon ship drills should be carried out on every ship covered by SOLAS (Safety Of Life At Sea, explained in the theoretical chapter). Abandon ship drill entails a risk of damage to the equipment and injury to the people handling it. The purpose of this study is to see into what is required to achieve a safe abandon ship drill. This is a qualitative study where the objective is answered by interviewing crew members that has experience of creating safe abandon ship drills. A total of ten crewmembers has been interviewed. The study shows that the safety of these drills is dependant on four factors; equipment, knowledge, cooperation and motivation. These factors where derived from previous reports, research and from the data obtained from the interviews. These factors are dependant on one another and can also be viewed as a spiral where one factor gives momentum to the next.

    En riskanalys av ECDIS Simulatorerna vid Sjöfartshögskolan i Kalmar2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Modern ships have the ability to navigate with the use of ECDIS only. ECDIS is dependent on many subsystems to function optimally. Failure Mode and Effect Analysis (FMEA) is a tool with which you can examine a specific system to detect potential construction errors and deficiencies in the production design. This thesis has used a FMEA to investigate ECDIS simulators at Sjöfartshögskolan in Kalmar to examine how ECDIS was affected when one or more of the subsystems connected to ECDIS have failed. The purpose of this study was to detect design errors, deficiencies and limitations of the ECDIS simulators at Sjöfartshögskolan in Kalmar. It could be demonstrated that some of the alarms in ECDIS that should alert the navigator that a subsystem has failed not has worked according to the manufacturer´s instructions. Additionally has some features of ECDIS not operated according to the manufacturer's instructions and some simulator functions which should test a specific situation in a safe environment have not worked.

    Ny som kapten på ett litet fartyg: Att föra befäl ombord på ett fartyg man saknar tidigare erfarenhet från2016Independent thesis Basic level (professional degree), 10 HE creditsStudent thesis
    Abstract [sv]

    Efter att ha tagit examen från det fyraåriga sjökaptensprogrammet på Kalmar Sjöfartshögskola söker vissa studenter anställning som befälhavare på ett fartyg under 70 brt trafikerandes inre fart. Utbildningen är utformad till att i första hand ge studenterna de förutsättningar som krävs för en anställning som styrman ombord på ett större fartyg. Syftet med denna studie var att undersöka hur de nyutexaminerade studenterna upplevde sin kompetens inför arbetet som befälhavare och ifall deras avsaknad av tidigare erfarenhet från fartygstypen gav upphov till några risker. En kvalitativ intervjustudie genomfördes med sex utvalda befälhavare som före anställningen saknade tidigare erfarenhet av fartygstypen. Resultatet visade att befälhavarna kände en nervositet inför delar av arbetet, främst kopplad till fartygsmanövreringen och avsaknaden av någon ombord att fråga om hjälp. De ansåg sig under arbetets inledande skede sakna den erfarenhet som krävdes för att under alla omständigheter kunna garantera fartygets säkra framförande.

    Nybyggnation för avloppsrening Tegelviken: En pumpanalys för kommande reningsverk2015Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Med en ny vattenreningsdel vill Kalmar Vatten AB (KVAB) sänka sina utsläpp av näringsämnen i Kalmarsund. KVAB har vid tidigare tillfällen uppgraderat det befintliga reningsverket och för att klara framtida energi- och klimatmål planeras därför en nybyggnation. Uppdraget var att framföra olika pumpalternativ till den framtida pumpstationen och ge en LCC-analys för varje alternativ. Två helt skilda pumptyper har utretts, Arkimedespumpen och centrifugalpumpen. Två alternativ för Arkimedespumpen och ett alternativ för centrifugalpumpen har tagits i beaktande. Under projektet har Kalmars inkommande dygnsflöde under åren 2011, 2012 och 2013 legat till grund för dimensionering av pumparna till den planerade nybyggnationen. Syftet var att ge KVAB beslutsunderlag för val av pump till den kommande pumpstationen. Resultatet redovisar att centrifugalpumpen har lägre energiförbrukning och får därför en lägre kostnad vid drift. Eftersom mer kringutrustning och underhåll krävs för centrifugalpumpen jämfört med Arkimedespumpen kan dock det verkliga resultatet bli annorlunda.

    Fartygsskydd och rollen som SSO: En kvalitativ undersökning om fartygsskyddet och SSOrollenombord på olika typer av fartyg efter införandet avISPS2016Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis is about ship security and the role of the SSO on different types of vessels. The purpose of the survey was to find out how the ship type and trade area of the ship affects how the on-board work with security and ISPS is conducted. The study was carried out during the summer and autumn 2015 by making qualitative semi-structured interviews with the SSOs on four vessels of different type in different trade areas. The vessels in the survey consist of a cruise ship in ocean traffic, a tanker in European traffic, a car carrier in world-wide ocean traffic and a ferry in short voyage traffic. In the study it was concluded that there are differences between both the investigated vessel types and trade areas, and that this affects how the interviewees: the SSOs perceive their role. The result indicates that the largest difference in the organization of ship security is found between the two main types of vessels in the study, between passenger ships and cargo ships, and that this difference can largely be explained by the size of the crew.

    Svaveldosering av biopanna: En utvärdering av doseringen med svavelgranuler för att minska utsläpp av kolmonoxid från biopannan hos Arvika Fjärrvärme2014Independent thesis Basic level (degree of Bachelor), 180 HE creditsStudent thesis
    Abstract [en]

    This study was performed in order to analyze and evaluate the effects of dosing sulfur to the combustion process in a bio fueled boiler. Equipment for this purpose was installed to the bio boiler at a district heating plant in Arvika in order to overcome high levels of carbon monoxide in the flue gas. The analysis has been carried out with regard to how well the sulfur dosage is fulfilling its intended purpose but also to possible side effects. Corrosion risks, levels of unburned sulfur in flue gas, flue gas condensate, air and bottom ash along with what happens chemically in the combustion process have been studied. Operational reports from the bio fueled boiler was studied and analyzed. To find out other effects of adding sulfur to the combustion a literature study was performed as well as direct contact with experts on the subject. CO content in the flue gas drops when adding sulfur to the combustion process. Laboratory analysis and operational reports indicate a presence of sulfur in the flue gas, flue gas condensate and fly ash and bottom ash. The results show that the levels are acceptable. The risk of causing corrosion in the plant by adding sulfur to the combustion is considered low. The current knowledge of what is happening chemically in the combustion process by the addition of sulfur is insufficient. Full-scale and laboratory experiments have been carried out without being able to show exactly how the sulfur lowers CO concentrations in flue gases.

    CV och personligt brev för nyutexaminerade fartygsbefäl i den svenska sjöfartsbranschen2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    As the competition for employment toughens amongst deck officers high effort is required in order to stand out from the crowd regarding job applications. The purpose of this study has been to investigate what content the Swedish shipping industry values most in CVs and cover letters. This was achieved by interviewing nine recruiters from different shipping companies and management agencies that recruit Swedish junior officers. A literature search regarding previous studies concerning recruitment provided a wider understanding of the subject and its relevance for maritime science graduates. The literature search also revealed a knowledge gap regarding recruiters in the Swedish shipping industry preferences about CVs and cover letters. The results of the study show some patterns and tendencies amongst the respondents, common to all of which is a preference of short and concise CVs and cover letters with content that is relevant for the applied position. The results also show that a job application is interpreted subjectively and therefore to some extent must be tailored to each individual employment opportunity.

    The power of the dollhouse: Comparing the use of full-scale, 1:16-scale and virtual 3D-models for user evaluation of workstation design2018In: International Journal of Industrial Ergonomics, ISSN 0169-8141, E-ISSN 1872-8219, Vol. 68, p. 344-354Article in journal (Refereed)
    Abstract [en]

    The benefits of having users evaluate product or workplace design during the development process are well known. This is often achieved by letting users interact with one or more models of the design proposal, in order to elicit feedback. The issue for product developers is to choose what type(s) of models to use (from paper drawings to physical or virtual mock-ups or fully working prototypes) and when to use them in the development process, while making optimal use of resources like time, money and personnel.

    This paper compares three types of simple three-dimensional (3D) models (1:1 scale, 1:16 scale and CAD) representing a ship bridge workstation, examining what kind of feedback they elicit in a design evaluation with representative users. Participants were asked to assess the proposed design and to compare the models' relative merits. The study found that while all three types of 3D models elicited several types of useful design feedback, there were differences in both quantity and content of the feedback elicited by each model type. The physical models elicited more feedback than the CAD model, both regarding content richness (direct and indirect design feedback) and quantity. The tangibility of the models seems to greatly influence acceptance and credibility.

    Using 2D and 3D models as tools during a workplace design process: a question of how and when2014In: Proceedings of the 46th Annual Nordic Ergonomics Society Conference, Copenhagen, Denmark: Danmarks Tekniske Universitet, DTU, 2014, p. 799-804Conference paper (Refereed)
    Abstract [en]

    The benefits of involving users in a development process are well described. This paper describes a procedure for using 2D and 3D models in a workplace design process, which is based on three rounds of user studies within the maritime domain. The process includes various kinds of models that can be used in order to elicit design feedback in a cost-effective manner. Design teams can greatly benefit from using such mediating objects to draw out the users’ previous experiences. It was found that different model types allow different levels of reflection and questioning of the design from the prospective users.

    Böta Kvarn kraftstation: Gammalt blir nytt2013Independent thesis Basic level (university diploma), 5 credits / 7,5 HE creditsStudent thesis
    Abstract [sv]

    Detta arbete inriktar sig att modernisera Böta Kvarn Kraftstation. Stationen är gammal och dess utrustning är i behov av en uppgradering. För detta ändamål togs de fram offertunderlag innehållande en teknisk beskrivning med tillhörande information angående kraftstationen. Denna skickades till flertalet leverantörer varvid Cargo & Kraft och Vattenkraftsbolaget svarade. Valet föll på Cargo & Kraft. Deras lösning är en semikaplan med tillhörande utrustning som teoretiskt kan generera ca 1.57 GWh per år. Detta ger en ökad produktion av 1,22 GWh och en ökad inkomst för kraftstation av ca 941 500 kr per år. Stationens tillgänglighet kommer via uppgraderingen att öka och anläggningen blir helautomatisk med bland annat sms-larm vid driftproblem.

    Utredning om modifikation av skrubberanläggningen på Peter Pan2019Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    AbstractSince MARPOL Annex VI took force in 1997, the limits ​​with in SECA (Sulphur EmissionControl Areas) have been stricter several times. This contributed to the vessel Peter Pan,owned by TT-Line AB, installed a scrubber in 2016. A scrubber enables the use of fuels with ahigh sulphur content and still meet the actual requirements. Since the scrubber was installed, ithas resulted in an increased workload for the crew on board. The goal of this study was toclarify if there are components in the system that cause frequent operational disturbances and ifthese can be replaced in order to reduce maintenance. To find out this a field study was doneon board the ship. This resulted in several components being observed and examined moreextensively. The compilation of the data collected during the field study showed that there areparts of the system that can be modified to extend the operating intervals. The conclusion washowever that the survey was going on for a too short period to give accurate results.

    Abstract [en]

    The purpose of the paper has been to verify how the environmental datasystem at Nybro Energi AB performs its calculations correctly and if the method is correct.

    An analysis of how the environmental datasystem's calculations are structured were checked. The calculations for errors and could, with the aid of DU-Teknik, create a template for comparison-calculations and other tests.

    The results compared the data values between the template and the environmental datasystem's calcualted boiler-efficiency at different intervals. It has also illustrated how each formula is structured for the environmental datasystem and how they are linked together.

    In conclusion, it can be determined that the environmental datasystem's calculations and the boiler efficiency calculations were consistent. Possible sources of error were measurement error, meaning that more accurate results would have been achieved by a more in-depth and thorough investigation, where all sensors and devices that provide environmental information to the computer could be checked.

    Finally, there is some improvement proposals for Nybro Energi AB to ensure that the environmental datasystem performs more accurate and realistic estimates.

    Digital tillsyn: En kvalitativ undersökning om hur maskinbesättningen till sjöss upplever en digital rond2015Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Tillsynsrond är en stor del av arbetsgången, för driftpersonal, i maskinrummet på ett fartyg. Det tillhör det förebyggande underhåll som tillämpas ombord. Idag använd till största utbredningen en metod som innefattar en färdig rondlista som skrivs ut på papper för att sedan kunna användas av driftpersonal vid rondering. Utifrån detta undersöka en ny metod för rondering till sjöss. Syftet med arbetet var att undersöka hur en digital rond uppfattas av maskinbesättningen. Genom att låta besättningen prova en digital rond skapad utifrån deras nuvarande rondlistor och sedan svara på frågor i en enkät, kunde en uppfattning byggas om en digital rond kan praktisk tillämpas till sjöss. Även om det kan tidsbespara arbetet och om besättningen tror det finns en framtid med metoden. Resultatet visar att de flesta i testgruppen ser en framtid med en digital rond och att det kan underlätta arbetet om metoden vidareutvecklas. Med detta digitala rondverktyg tog dock ronden längre tid.

    Mind the Gap!: Maritime education for gender-equal career advancement2015In: Maritime Women: Global Leadership / [ed] M. Kitada, E. Williams & L. L. Froholdt, Berlin Heidelberg: Springer, 2015, 1, p. 143-154Chapter in book (Refereed)
    Abstract [en]

    Seafaring as an occupation, and the maritime community as a whole, is still a male-dominated industry. In order to encourage more women to engage in a career at sea, a number of campaigns have been launched by various stakeholders. Since gender gaps in education generally are larger in the developing world, while steadily closing in the developed countries, it is both understandable and appropriate that efforts largely have been directed towards enabling women in developing countries to engage in professional education and training, may it be maritime or other. However, is opening the door and encouraging women to participate in maritime training sufficient to keep and encourage women to embark on a maritime career?

    In this paper, we set out to examine how gender equality is addressed in the curricula of maritime education. A document analysis was performed, examining official study plans and curricula from eight maritime universities in Finland, Norway, Sweden and the Philippines; all nations ranked in the top five in the Global gender Gap Index. The results show that gender issues are not explicitly mentioned or addressed in these documents, indicating a lack of clear strategies for these matters. Educational institutions are important bearers of societal norms and values. Without effective gender-inclusive strategies and pedagogical and didactic approaches, there is a risk of reproducing inequality, instead of producing equality. Increasing numbers of female students will not alone close the gender gap in the maritime industry. Gender issues must be well defined, operationalised and included in educational policy and curricula-making at individual, structural as well as symbolical levels.

    Breaking the ice: a work domain analysis of icebreaker operations2018In: Cognition, Technology & Work, ISSN 1435-5558, E-ISSN 1435-5566, Vol. 20, no 3, p. 443-456Article in journal (Refereed)
    Abstract [en]

    Icebreakers are special-purpose ships designed to operate in different ice-covered waters, either independently or duringassistance of weaker ships. In the Baltic Sea, as well as elsewhere, they are essential for maintaining continuous sea transportservices during wintertime. Icebreaker operations are complex, and every situation in which a vessel requires assistanceis unique, due to, e.g. changing ice and weather conditions, geographical location or language proficiency of the crew onboard the icebreaker or assisted vessel. The icebreaker crew has considerable freedom to adapt to each situation, yet, forsafe operations, there are constraints to which the crew has to conform. The study presented in this paper aims at identifyingthe constraints on nautical officers on board icebreakers during operations, as well as special situations that increasecognitive load. A work domain analysis based on a group interview with nautical icebreaker officers shows the multitudeof tasks performed on board icebreakers. Furthermore, it identifies constraints specific to icebreaker operations such as iceassessment and direct icebreaking, but also generic constraints such as language and communication skills. At times, safetyand efficiency come into conflict, resulting in a trade-off between the two. When that happens, safety gets priority, and theoperation stops until the situation has been evaluated. In addition, several situations that increase cognitive load are identified,with the common denominator that they add elements of uncertainty, e.g. severe weather and technical malfunctions.Finally, further research within the area of icebreaker operations is recommended, with a continued focus on the systemconstraints, and their potential for system improvement.

    Mind the Gap!: A quantitative comparison between ship-to-ship communication and intended communication protocol2020In: Safety Science, ISSN 0925-7535, E-ISSN 1879-1042, Vol. 123, p. 1-8, article id 104567Article in journal (Refereed)
    Abstract [en]

    Icebreaker operations, when an icebreaker assists other vessels through ice-packed fairways, are hazardous due to harsh environmental conditions and complexity of procedures. The severity of operations is further aggravated by the necessity for maintaining a small distance between the vessels, which consequently increases the risk of collision. Even though miscommunication is widely identified as a contributing factor to shipping accidents, previous research within winter navigation has focused largely on technical aspects of icebreaker operations to increase the operational safety. This study aimed to investigate to what extent closed-loop communication is used during icebreaker operations, and whether this practice deviates from stipulated communication protocols. A quantitative analysis was performed, coding 40 days of verbal radio communication. Subsequently, the data was compared to the stipulated communication protocol outlined in the Standard Marine Communication Phrases. The results show that closed-loop communication is not utilized to its full extent. Some message types are completely repeated at a higher rate, mainly instruction and question, while other message types, such as information and intention often receive a yes-no answer. A full closed-loop, i.e. a completely repeated message followed by a confirmation, was only observed in 16.4% of the messages initiated by an icebreaker and 14.0% for the assisted vessels. Thus, this study clearly shows that there is a gap between actual language use and stipulated communication protocol. Finally, since misunderstandings during icebreaker operations can have serious consequences, more research is needed into the underlying reasons for miscommunication in situations with little room for error.

    Simulating Advanced Arctic Operations - Lessons Learned2014In: 18th International Navigation Simulator Lecturers' Conference / [ed] Sam Teel, Massachusetts Maritime Academy, USA, 2014Conference paper (Other academic)
    Abstract [en]

    The use of simulators is widely used for preparing someone, be it a person or organization, for an upcoming task. There are several reasons for this. Many endeavours are costly, and the gain from a real life experience might not justify its costs. Another reason might be that the task involves hazardous elements, with potential to harm people or the environment. There is also the possibility that the experience sought occurs so infrequently, that one is unlikely to experience it under real conditions. In all of these situations, a simulated training experience can be equally good, or even better, compared to real on-the-job training.

     This paper gives an account of a course in advanced arctic operations, where the simulator was used in preparation for operations in ice. The preparations and execution of the training itself are explained, accompanied by the views of the course instructors about the lessons learned. The result indicates that one of the key components of successful training is to avoid having too detailed exercises, and rather to focus on the fundamental principles of the upcoming activity. In combination with the important debriefing where more specific aspects of the operation can be discussed, a broad training leaves the participant well equipped to handle real life challenges as they appear in the field.

    Improving operational safety during icebreaker operations2017In: WMU Journal of Maritime Affairs (JoMA), ISSN 1651-436X, E-ISSN 1654-1642, Vol. 16, no 1, p. 73-88Article in journal (Refereed)
    Abstract [en]

    The study presented in this paper aims at investigating what safety measures that can be taken to improve the operational safety during icebreaker operations in the Baltic Sea. During icebreaker operations, the icebreaker and the assisted vessel operate in close proximity to each other, a distance which can be even smaller if weather and ice conditions are severe. This poses a severe threat to the operation, since the extremely short distance between the vessels leaves no room for error. The results, which are based on data collected through individual interviews and questionnaires, indicate several possible improvements. Firstly, on a regulatory level, the introduction of an ice navigation certificate for deck officers would set a minimal level of formal competency. Secondly, on a knowledge level, more ice navigation training and better language skills work in favour for the safety. Thirdly, on a technical level, having an electronic chart with target tracking capability increases the efficiency and safety of the passage through ice. In addition to these results, this study shows a need to further research the communication and language situation during icebreaker operations.

    Abstract [en]

    The aim of this work was to investigate how it is to move in hierarchy from crew to

    officer within the seafaring profession and how to be affected by this. How you are

    perceived by the crew when going from to represent a part of a system to represent a

    different part of the same system and if you are ready to assume the responsibilities of the

    new role entails?

    This is relevant and interesting as we will soon is facing at this transition. The work is

    based on a qualitative approach. The choice of this method gave the information needed

    for a perfect result.

    Interviews were conducted through personal meetings with active officers which also

    provided the opportunity to ask follow-up questions and the respondents were given the

    opportunity to share their experiences. The results showed that the transition from crew to

    command seems to be something individual from person to person but consistently has

    been the feeling that it is a major challenge of excitement and some nervousness.

    The largest portion prior to having been men from before is that it felt familiar with the

    safety procedures on board and to have a basic sense of security regarding departures and

    mooring, loading and unloading.

    Most felt that it was difficult to give orders to his old sailor colleagues but afterwards it felt

    more natural.

    Framtidens LNG-tankfartyg: En studie om framdriftsanläggningar för LNG-tankfartyg2014Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study consisted of analysing the current situation on the market for propulsion systems for LNG-carriers. The purpose of the study was to create a relevant picture of what the situation looks like today and through interviews try to predict how the situation might come to change.

    By using already existing literature the authors reviewed the situation on the market as it is today and formed relevant questions. After the questions had been formed the authors contacted several companies associated with the LNG-carrier market. Interviews with these companies were carried out and it is through these interviews possible to analyse how the situation might come to change.

    The study has shown that there is one system that dominates the market for LNG-carrier propulsion, DFDE. There is however a new system, with dual-fuel two stroke engines that is expected to take over a part of the market in the near future. Other propulsion systems such as steam propulsion plant and a system with a gas turbine exist on the market but the interest in these systems is limited.

    Arbetsmotivationen på däck: Vad kan överstyrman göra och vilka andra aspekter påverkar arbetsmotivationen på handelsfartyg2018Independent thesis Basic level (professional degree), 180 HE creditsStudent thesis
    Abstract [en]

    In this thesis perceptions of the role of the Chief officer in relation to the crew's motivation for work has been investigated. Data has been collected from eight people who worked as Chief officers through a questionnaire and interviews which has given qualitative statements in three main areas: Motivational measures from Chief officer, Other factors influencing motivation, and Organizational support for the Chief officer. A majority of the interviewees indicate that important for motivation are: The content of the work and that it feels meaningful and the cohesion of the working group. Of particular importance for the respondents are to provide employee responsibilities and to give feedback on accomplished work, create involvement for the operation onboard, as well as using objectives and results follow-up. Their behavior towards the ratings are important. Other factors that are important for the motivation include: Employment conditions, Food, Recreation Activities, Gym and Internet. The organizational support for the Chief officer has been found to be relatively weak and are also not sought after by the Chief officers to any greater extent. The factor considered most important and effective factors are clear objectives and expectations from the Master.

    Maskinbefäls utbildning på integrerade övervakningssystem ombord nybyggda fartyg2017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    During construction of new ships or modernization of ships, integrated automation systems is often installed in the engine control room. It is of importance that the responsible engine officers are familiar with how the system works and that they can perform troubleshooting if eventual faults occur. The aim of the present study is to investigate whether the engineer officer get enough training on new integrated surveillance systems to perform their duties in a safe and secure manner. In this study a questionnaire was sent to engine officers signed on new ships where they got the opportunity to give their answer how they experience the possibility to be trained and acquire knowledge how the systems work. The majority of the engine officers who answered the questionnaires felt comfortable to operate the ship safely. The study showed that the training courses offered often were product specific instead of installation specific, which was not optimal because there can be differences between construction and handling after installations of the same products. The survey showed that a majority of the officers had not been offered training on the monitoring system. The officers who were not offered training expressed a wish to be able to participate in training. Training on the system is offered by the manufacturer but often only a few of the engine officers is offered training by the shipping company. Earlier studies show that crews that participates in the building and delivery process on the shipyard or during installation of a new system receives training on site, the officers that come onboard as reliever after trial run, maiden voyage or during normal operation often have to learn by doing. The conclusion is that the officers should be given the opportunity to participate in training before signing on and also a follow up training course after working with the system for a while. To give the relieving officers a chance to familiarize themselves and assimilate knowledge of the system, there have to be more time available in conjunction with leave.

    Abstract [en]

    The main purpose of this thesis was to explore nautical officer’s attitudes towards the alarms they may encounter on the bridge and the eventual causality between the officers and their actions concerning the alarms. Earlier research into alarms and research regarding optimization of bridge-layouts presented a problematic theory which Papastavrou and Lehto call cry-wolf. Wherein the operators of systems, or ships, with advanced alarms tend to ignore the alarms if they are subjected to a high frequency of alarms, or alarm-floods as Al-Dabbagh and Tongwen calls it. This study shows that, on board the vessel which the study was conducted, the cry-wolf phenomena exist. The study was conducted on board a Swedish vessel from the hermeneutical perspective. The data collection was done with the qualitative method, primarily through semi-structured interviews and these were then enriched with data from unstructured observations which were made during a nine-day stay aboard said vessel. The collected data has been analysed through content analysis from the hermeneutical perspective and the study reveals that the officers tend to ignore the alarms, unless they are classified as emergency alarms. This study proposes two potential fixes for how to make the alarms less overwhelming and how to give back the importance of the alarms. Furthermore, the study presents a hypothesis which aims to find whether or not a given vessel is subject to the cry-wolf phenomena. This hypothesis needs to be proven in future research before it can be proclaimed as a valid hypothesis.

    This thesis focuses on study of the employment market for graduates from the Master Mariner degree that graduated in 2010, 2013 and 2016. It is a comparison between the three years of graduation within two Swedish universities that offer the Master Mariner programme. Data collection with combined quantitative and qualitative techniques within a mixed-mode study. Results show a majority occupied within the maritime sector, although vessel-based employment has decreased compared to past studies and redundancy is an emerging element. The percentage occupied within the vessel-based sector is higher in Kalmar Maritime Academy, Linnaeus University, compared to Chalmers University, the results from which show a higher concentration in shore-based occupation. The conclusion of this thesis is that the employment market for graduates from maritime institutions in Sweden is undergoing change.

    This thesis is focused on ambulance staff in a ship environment and the communicationbetween the ambulance staff and the ship’s crew. The purpose is to see if the ambulance staffconsider themselves qualified to make a risk assessment of a ship environment by ownknowledge and to investigate if there is a need to improve the communication between thecrew and the ambulance staff.The background to the study is the accident with the bulk carrier Saga Spray when two of theambulance staff were poisoned by carbon monoxide and one of the ship’s crew memberdeceased.We have chosen a qualitative research method and conducted semi structured interviews withthe ambulance staff, and a document study where accident reports from authorities areexamined.The result of this study shows that the ambulance staff does not consider themselves to haveenough knowledge to identify risks onboard and that they depend on the ship’s crew informingthem. Any communication problem with ship’s crew is not experienced.

    Abstract [en]

    This is a survey of students' interest in an area specialization in the Nautical Science program at Kalmar Maritime Academy. The aim was to investigate the interest within the student community regarding introducing elective courses of 7.5 credits in the second half of the program. The general opinion in Swedish shipping is that the nautical science program at Kalmar Maritime Academy is a broad education. The program has no elective courses and specializations available; this at a time when the work as an officer is becoming more and more specialized.

    The study was conducted through interviews with two final year students of 2013 and three active officers who graduated in 2012. All respondents who were interviewed had studied or were studying at the time of the interview at the Nautical Science program at Kalmar Maritime Academy.

    The study showed a desire among the respondents regarding increased eligibility in the program but also unwillingness to compromise the width of the education. The respondents emphasized the importance of having the possibility to study CCM and DP-Basic, partly for an improved competitiveness in a strained labor market and partly due to fact that these courses are often required within the employment sector to which a large number of students will approach.

    Abstract [en]

    The SOLAS regulations for merchant vessels states that in the event of loss of power, a backup power supply will start automatically. This paper investigated the possibility to replace the widely-used generator driven by a fossil-fuel powered internal combustion engine, with a UPS. Focus of the investigation included regulations concerning the use of accumulators onboard, market product range fulfilling the legal requirements and price difference based on purchase price and maintenance costs for 25 years. The cost results where compared as a Life Cycle Cost calculation. Regulations by the Swedish transport agency and the Classification DNV-GL allow the use of emergency power from accumulators or generator.

     

    For the possibility to investigate through cost estimations, a theoretical model of a merchant vessel with Swedish flag, was set up. All companies contacted were Swedish manufacturer. The results in the LCC show the situation of today and lets us know that the most cost efficient investment is the conventional emergency generator.

    Problems with fractures due to fatigue have been known since the early 19th century, and the phenomenon has been studied since then. After long periods of work, a methodology has been found to develop analytical fatigue calculation models for steel structures. The purpose of this work has been to investigate the fatigue assessments of marine boilers during it ́s economic lifetime. In this study, an analytical calculation has been made of the marine boiler using DNV's ship classification rules and the European pressure vessel standard. In the study, the authors have taken into account the boilers pressure variations, temperature variations, and the marine boiler's external impact from the vessel's motion in the water and the resulting forces. In order to be able to protect human life, nature and the environment, physical property (ships and cargo), operational availability as well as laws and regulations, with high reliability (confidentiality).

    Abstract [en]

    At sea, a strict hierarchy is the natural chain of command. This ranges from the captain to the individual sailor. The Chief Officer, second in command on deck, has many areas of responsibility. For instance, he or she is commonly in charge of prioritizing aspects of ship maintenance, supervise and manage crew work-orders and the main responsibility for loading and discharging cargo. With this in mind, it is not hard to imagine that a mustered chief officer will experience a variety of conflicts on-board, both work related and personal. The purpose of this study is to answer what conflicts are the most common from a chief officers perspective on-board a merchant vessel. Also it will gauge if there are any specific conflict management methods that are used by chief officers to advert or intervene in the conflict situations that can arise. The concluding section of this study will look at the possibility and interest for chief officers to attend a course in conflict management to further develop their tools within this area. Through in-depth interviews with active chief officer the result showed that the most common conflicts were perceived as the ones that arose from everyday problems on-board. These minor issues, if left to their own accord, tend to escalate. From a conflict management perspective, all findings indicate that chief officers tend to use a predefined strategy in regards to solving or manage conflicts on-board. However, all respondents agree that further education within the field would surely benefit them as individuals and also the on-board culture as a whole.

    Hydroxylated and methoxylated polybrominated diphenyl ethers in long-tailed ducks (Clangula hyemalis) and their main food, Baltic blue mussels (Mytilus trossulus x Mytilus edulis)2016In: Chemosphere, ISSN 0045-6535, E-ISSN 1879-1298, Vol. 144, p. 1475-1483Article in journal (Refereed)
    Abstract [en]

    Long-tailed ducks (Clangula hyemalis) that breed in northern Europe and western Siberia and commonly winter in the Baltic Sea, are threatened by a significant population decrease. The ducks are, by primarily feeding on Baltic blue mussels (Mytilus trossulus x Mytilus edulis) while wintering in the Baltic Sea, potentially subjected to high levels of toxic hydroxylated polybrominated diphenyl ethers (OH-PBDEs). To assess long-tailed ducks exposure to polybrominated phenols (PBPs), polybrominated anisoles (PBAs), hydroxylated polybrominated diphenyl ethers (OH-PBDEs), their methylated counterparts (MeO-PBDEs) and polybrominated diphenyl ethers (PBDEs), livers of ten long-tailed ducks wintering in the Baltic Sea were analysed. Pattern and levels of analytes in long-tailed ducks (liver) and blue mussels sampled in March and May at nine sites in the Baltic Sea were compared. The geometric mean concentration (ng/g l.w.) in livers of long-tailed ducks and Baltic blue mussels were: ∑2PBPs: 0.57 and 48; ∑2PBAs: 0.83 and 11; ∑7OH-PBDEs: 6.1 and 45; ∑7MeO-PBDEs: 3.8 and 69; ∑7PBDEs: 8.0 and 7.2, respectively. Based on an estimated daily intake of 450 g fresh blue mussel meat, long-tailed ducks daily dietary intake of brominated substances while foraging in the Baltic Sea in March-May was estimated to; 390 ng ∑2PBPs, 90 ng ∑2PBAs, 370 ng ∑7OH-PBDEs, 590 ng ∑7MeO-PBDEs and 59 ng ∑7PBDEs. The low levels of PBPs, PBAs, OH-PBDEs and MeO-PBDEs in the long-tailed duck livers compared to blue mussel, despite a continuous daily intake, suggest that these compounds are poorly retained in long-tailed ducks.

    Abstract [en]

    On August 20, 2013 the Maritime Labour Convention 2006 entered into force. This study has through interviews with navigating officers onboard Swedish flagged vessels and through a literature study, examined the effect of the new Convention seen from the navigating officers’ point of view. The purpose of this study was to gain insight into how the Convention effected the crew and examine how the requirements are complied with and what changes has been made onboard in regards of hours of work, hours of rest and manning levels. The interviews revealed that no major changes have been made onboard as result of the implementation of the Convention. The reason for this is that most of the requirements of the Convention was already implemented in Swedish law. It appeared, however, that seafarers are experiencing difficulties in meeting the demands regarding hours of rest and that this is not being documented truthfully. The reason for this is percieved to be that the manning levels onboard the ships today is not sufficient. The results show that many solutions exist to this problem, and that greater demands needs to be placed on shipowners and flag states for a change to take place.

    Abstract [en]

    This thesis is part of a major project that the Port of Gothenburg has embarked upon, and is produced as a result of a project directive. The purpose of that project is to renew its current fire protection in Energihamnen (the Energy Port) but also meet future requirements. The purpose of the present study is to examine what expectations shipping companies and ship´s officers, which regularly arrive to the Energy Port, have on the Port of Gothenburg’s fire prevention systems and fire emergency plans. Further investigated are the requirements that form the basis for the fire protection equipment onboard tankers that regularly arrive in the Energy Port. To obtain answers from the above mentioned purpose, interviews were conducted with three ship owners and five ship officers, and this was combined with a literature summary which consists of the regulatory framework that places specific requirements and recommendations for the fire prevention equipment that will be on board tankers. The interviews were conducted to include the shipping industry's expectations of the Port of Gothenburg’s emergency procedures during cargo operations. The result shows that the majority of respondents expected that the Port of Gothenburg should have firefighting equipment on their docks that can extinguish fires onboard the ship’s deck. They also expected that the port's emergency response plans should be well rehearsed and should also quickly come into force during an emergency.

    Liquified Natural Gas Marine Fuel: Naturally Occuring Radioactive Material2019Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    There seems to be enough information available on how different types of radiation may affect human health. There also seems to be adequate research made about NORM and how to handle this phenomenon. The image put forth by this study shows that the appearance of NORM within affected industries do not appear surprising or difficult to deal with. On the contrary it seems to be a well-known issue and safety measures have been adapted accordingly. It appears as if these issues have been overlooked regarding the systems where LNG is being used as a marine fuel. There is not enough data to conclude whether NORM is an issue or not in such systems.

    Nätverksoptimering med öppen källkod: En studie om nätverksoptimering för sjöfarten2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The thesis describes how network traffic transmitted via a satellite link can be optimized in order to reduce loading times and transmitted data. The purpose with this study has been to determine what methods are available to control and reduce the amount of data transmitted through a network and how this data is affected. By applying the practice of DNS caching, web caching and ad blocking with the use of pfSense as a platform the study has performed experiments targeting different web sites and measured the loading times and amount of transmitted data. The results showed good possibilities to optimize the network traffic and the measured values indicated a reduction of the network traffic of up to 94% and loading times with 67%.
