The government invests SEK 25 million a year for ten years, a total of SEK 250 million, to reduce environmental hazards from shipwrecks along the coasts of Sweden. According to the government, between one and three environmentally hazardous shipwrecks can be remediated each year. SwAM is responsible for carrying out this investment in the environment by prioritizing which shipwrecks that will be subject to detailed investigation and subsequent recovery of oil and ghost nets. The prioritization and the risk assessment is carried out with the risk assessment tool, VRAKA, developed by Chalmers University of Technology. See the location of the 30 most environmentally hazardous shipwrecks on our webpage. During 2017 and 2018, recovery operations were performed on the shipwreck Thetis, near Smögen on the Swedish west coast, and oil and a ghost net (purse seine) were recovered. Oil recovery operations were also performed on the shipwrecks of Sandön and Hoheneichen near Ystad. Furthermore, during 2018, SwAM in collaboration with the Swedish Navy, also performed a large diving operation and detailed examination of the shipwreck Skytteren, near Lysekil on the Swedish west coast.
