The 2250 dwt freighter Celina in the Baltic Sea off the Swedish coast reported that it had damage to a wing tank. The damage resulted in a 10 to 15 degree list causing the vessel to heel. The damage allowed water ingress from the wing tank into the cargo hold. The crew of 4 on board stated that the list is undercontrol with bilge pumps. Reports state the vessel will need further inspection of damage before it can proceed.
