MarineShaft has recently carried out a complete renovation of the propeller equipment from cargo vessel MV Karina Danica.
MV Karina Danica is now back in operation after a planned drydocking stay at the shipyard NAUTA in Gdansk/Gdynia, Poland.
During the docking, it showed a leak somewhere in the stern tube system. Oil was found in the hub and pitch propeller blades, and seawater had run into the system and caused cavitation.
The owner of MV Karina Danica H. Folmer & Co. decided to send the propeller equipment to our workshops in Denmark.
The equipment was disassembled, cleaned, and thoroughly measure/tested.
