Sir Bedivere

A & P Falmouth Ltd had won the contract to overhaul RFA Sir Bedivere, before the ship was sold to the Brazilian Navy. M & A Engineering Ltd were tasked with repairing the port & starboard prop shaft bearings, with the shafts remaining in the ship.

 

 

Sir Bedivere

 

Both Port and Starboard prop shafts each have two, aluminium bronze bearing areas. Each bearing was circa Ø330 x 1.5m long. Wear had occurred in the bearing surfaces, so the machining repair was to re-establish true and concentric diameters on each shaft. To remove the shafts from the ship would of required cutting through the hull in order to extricate the shafts; M & A Engineering undertook the repair, in-situ.

The in-situ repair not only saved considerable expense to the yard, by virtue of the shafts remaining onboard the ship, but also ensured the refit programme remained on schedule.
