Two offshore support vessels (OSV) operated by offshore oil and gas marine support specialists MMA Offshore have undergone engine overhaul programs, diesel power specialist Royston Australia said.
The work scope saw Royston engineers undertake the DG2 M/E and DG3 M/E services on the diesel electric Caterpillar generator engines on board the MMA Plover and its sister vessel MMA Brewster, while they were on passage.
The contract involved preparing, packing and shipping parts to undertake a major overhaul of the MMA Plover’s DG2 and a straight top end on the MMA Brewster’s DG3.
In back-to-back operations, Royston engineers disassembled the diesel generators to renew cylinder heads, liners and seals, inspect and clean water and fuel manifolds, re-seal crankshafts, replace fuel transfer pumps, inspect the generator drive couplings, and replace lube oil pumps.
Engineers also carried out a comprehensive inspection of vibration dampers, electrical sensors and switches, engine wiring systems and valve/injector units before completing load testing.
Royston’s operations manager Matty Burbidge, said, “The work was undertaken while the vessels were at sea. This can often involve working in unfavourable sea conditions, particularly during the cyclone season, and to extremely strict timeframes.
“Royston specializes in this type of work, providing significant savings for vessel operators without compromising on the quality and standard of engineering work.”
