The Salvage of m/v Vera Su

MSB Managing Director was awarded the Presidential Barge of Honour by the President of Bulgaria for “outstanding contribution in the refloating and salving of m/v Vera Su” in October 2021.


The vessel presented major environmental threat/catastrophe as it grounded in the rocky area of Kamen Bryag, Bulgarian coast (protected environmental area) with 2,830 mt of fertilizers and significant MGO bunkers. The vessel grounded on four major rocks at least and had 100% of the Ballast Water and MGO double bottom and wing tanks compromised. The cargo hold, the Engine room, the entire forecastle and 30% of the accommodation block were fully flooded


MSB was responsible for the strengthening of the vessel’s structure and the cargo discharge/water pump-out strategy and sequence. Provided advice for the marine operations and arrangement of tugs as there were rocky areas all around. MSB remained on the vessel in charge of the entire discharge/lightening, welding hull reinforcements, refloating operations and tow to the safe harbour of Varna, Bulgaria


Our Engineering Division lead by Evgeniy Dimkin performed the engineering calculations for hull strengthening and refloating operations. This was significant challend as all double bottom and side tanks were ruptured and compromised.


MSB Managing Director was awarded the Presidential Barge of Honour by the President of Bulgaria.
The Minister of Transport awarded the Manager of the Engineering Division Evgeniy Dimkin with Honorary Diploma for the performing the engineering calculations.
