Casualties to Tankers in the Baltic 1960–1975

Data relating to a total of 74 tanker casualties in the Baltic area during 1971–5 have been analysed and compared with the earlier collected data on 268 tanker casualties. The discussion concerns local and seasonal distribution. The statistics also cover the nationality, age and size of ship involved. Emphasis is laid upon the need for a more efficient casualty reporting system and new methods of data collection are presented. The Baltic, Gulf of Bothnia and Gulf of Finland form a limited sea-water basin, where the change of water is small and the evidence of man marked. One of the worst threats to the sea water is the oil leaked from ships. This oil gets into the water in ship casualties or by accidental or deliberate discharge of spill oil into the sea. The oil amounts leaking into the water are very large in ship accidents if the ship or ships in question are tankers in loaded conditions and tanks are damaged.
