Bow thruster leak
After our inspection in the dock, our engineers discovered a leak in the underwater housing of a Schottel STT170. Cavitation (formation and abrupt collapse of vapor-filled bubbles) had created a hole in the house. We have therefore disassembled the bow thruster and brought it to our workplace. The underwater housing has been replaced for a new Ni-Resist underwater housing. We sent the bow thruster back to the yard, so that they can install it and use it for many years to come.
