Royston engine overhaul for OSV

A change in operating schedules for the E.R. Georgina required a fast four day turnaround of 24 sets of cylinder heads, piston and connector rod assemblies and bottom end bearing blocks that had been removed from the vessel as part of the maintenance of its Rolls Royce Bergen engines.

Simon Richardson, operations manager, Royston, said: “Platform supply vessels are specialised high tech ships and command valuable day rates. In the event we were able to complete all the work in four days and return the fully renewed parts to enable the vessel so that it was ready to resume operations.”

The on-board engine service work was carried out by the ship’s crew alongside Rolls Royce and Babcock engineers. The parts requiring maintenance and repair were delivered to the specialist Royston diesel engineering workshops in Newcastle, where the engineering team carried out the comprehensive inspection, service and maintenance of all the components.

The work specifically involved the inspection and pressure testing of 18 cylinder heads and the complete overhaul, cleaning, measurement and re-building of a further six.

Full cleaning, inspection and crack detection was carried out on the piston and con rod assemblies, and the bottom end blocks, before all parts were fully re-calibrated to the required specifications.
