Royston completes OSV overhaul

Royston engineers undertook the 18,000 running hours service of a Scania DI12 harbour generator, which is onboard the 80m length Highland Chieftain, while the vessel was moored in Aberdeen.

“Royston always provide a good quality service using experienced engineers, who are knowledgeable on the engine type they are working on,” commented Gary Bartlett, operations superintendent at Tidewater Marine.

The work involved the generator being disassembled with manifolds, turbo, rocker gear, critical pumps, pistons, liners, oil cooler, fan and belt guards stripped out along with the camshaft for inspection and where necessary, either repaired or replaced.

All parts including the engine block were cleaned while the aftercooler was also stripped down at Royston’s test and repair centre in Newcastle upon Tyne, UK before being cleaned and rebuilt. New turbo, water pump and thermostat units were also fitted before the whole power plant was reassembled and tested for operational performance.

“The work on Highland Chieftain shows that we have the adaptability along with the inhouse resources to respond extremely rapidly to customers’ needs with a highly skilled and efficient engineering team,” said Shaun Cairns, Royston’s operations manager, said.

The Highland Chieftain is a purpose-built support vessel and is part of one of the largest fleets of OSVs in the industry.
