C3/1997M Dredger KUOKKA PEKKA 5, Capsizing off Olkiluoto on 19.4.1997

Tug NICO was towing a barge and dredger, KUOKKA PEKKA 5 from Kotka to Mäntyluoto 19th of April 1997. During the last part of the voyage, from Rauma to Mäntyluoto, the dredger capsized off Olkiluoto at 17.02. The tug was able to continue the tow the dredger being upside down. In-vestigation showed that the reason of this accident was a hatch left partly unlocked. During the voyage after Rauma on open sea, waves gradually filled the left winch room through this hatch. Finally the dredger lost its stability and capsized.
