Repairs to Bow Thruster Drive Shaft Bearing Housing on Stena Europe

The Stena Europe was found to have excessive wear in the lower housing bore for the bow thruster drive shaft during a dry dock inspection. The best solution would be to bore out the existing housing to accept a sleeve which, in turn, would have to be machined out to return the housing to its original dimensions - exactly.

The ships engineers also wished to check the angularity between the Drive Shaft and Bow Thruster Shaft, where the pinion gears mesh. M & A utilised one of its range of heavy duty line boring bars to replicate the position of the Bow Thruster Shaft. When the vertical bar had been set in the drive shaft housing bores, a sweep reading was taken across the horizontal bar. No error was found.
