The Ballast Water Management Convention : How Swedish tanker shipping companies have dealt with the Convention's regulations (English)
Abstract [sv]

Främmande organismer i fartygs barlastvatten har med sjöfarten spridits runt världen med förödande konsekvenser. För att reglera denna spridning infördes Barlastvattenkonventionen av IMO, som innebär att fartyg inom en viss tid måste investera i godkända barlastreningssystem. Konventionens implementering har skapat ett visst huvudbry och rederier har ställts inför utmaningen att välja system som passar deras fartyg och fartområden. En kvalitativ intervjustudie genomfördes med representanter från svenska tankrederier för att få en bild av hur de har hanterat konventionen. Vidare undersöktes på vilka beslutsgrunder olika reningstekniker valdes samt hur eventuellt installerade system har levt upp till förväntningar. Intervjustudiens resultat visade att samtliga rederier har påverkats ekonomiskt och upplever problem med att hantera konventionens implementering samt att hitta tillförlitliga barlastreningssystem. En rapport kom även fram under intervjuerna där Saudiarabien hade gjort omfattande provtagningar på fartygs barlastvatten som visade att ett anmärkningsvärt stort antal fartyg med IMO-godkända barlastreningssystem inte klarade utsläppskraven. Intervjustudien indikerar påtagliga brister i barlastreningssystemen som Saudirapporten även bekräftar.

Abstract [en]

Aquatic invasive species have spread around the world in ships’ ballast water tanks with dire consequences. To regulate this spreading, the International Maritime Organization implemented the Ballast Water Management Convention which forces ships to, within a certain time frame, install approved ballast water treatment systems. The implimentation of the Convention has been complex and shipping companies have had to face challenges of choosing suitable treatment systems for their ships and trading areas. For this study, qualitative interviews were conducted with representatives from Swedish tanker shipping companies to examine how the Convention has affected them. On what grounds different treatment techniques were chosen was also examined, as well as if installed treatment systems have met expectations. Results from the study show that companies have suffered economical impacts, have had difficulties handling the implementation of the Convention as well as difficulties finding reliable treatment systems. Furthermore, one respondent referred to a report submitted by Saudi Arabia where extensive ballast water sampling had been conducted on ships calling their ports. The report showed that a considerable amount of ships with approved ballast water treatment systems did not meet the required levels of organisms in the treated ballast water. The interviews confirm the report’s description of the treatment systems’ fundamental flaws.
