Most of the hazardous shipwrecks that SwAM works with have no owner. The company that once owned the ship may have been dissolved, gone bankrupt or does not exist any longer for any other reason. So there is no owner to claim responsibility from. If the vessel wrecked before 1969, liability under Chapter 10 of the Swedish Environmental Code cannot be demanded either, since the Code is not applied to activities before -69. The statutory limitation period according to the Swedish maritime code (Chapter 10) for oil or bunker oil damage of three years from the date on which the damage occurred, or at the latest within six years from the date of the accident. In many cases this period has already expired.
