German m/s Europa spewed waste oil, hitting both the ground and sea, at the Katajanokka terminal on Sunday.
The accident occurred when a hose channelling bilge water to a container tank came undone. As a result, waste oil erupted from the unfastened hose at high pressure, causing oil to land both on the asphalt as well as in the sea. The ship was docked at the time of the accident.
Between 50 and 60 litres of oil gushed from the ship, ten litres of which shot into the sea, estimates Petri Strandberg of the Erottaja Rescue Station.
The m/s Europa departed for St. Petersburg on Sunday afternoon, however, half an hour behind schedule due to clean-up work.
