Royston completes new engine overhaul work for Tidewater Marine fleet

Marine engineering and propulsion specialist Royston has completed the rapid overhaul of a diesel power plant system onboard a Tidewater Marine operated platform support vessel.

Drawing on its extensive capabilities and resources, 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.

The work involved the generator being disassembled with manifolds, turbo, rocker gear, critical pumps, pistons, liners, oil cooler, fan and belt guards all being 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 specialist test and repair centre in Newcastle upon Tyne before being cleaned and rebuilt. New turbo, water pump and thermostat units were also fitted as part of a comprehensive package of engineering work and support before the whole power plant was reassembled and tested for operational performance.

Gary Bartlett, operations superintendent at Tidewater Marine, said:

Royston always provide a good quality service using experienced engineers, who are knowledgeable on the engine type they are working on. Having used Royston on multiple occasions previously, I will certainly continue to use their services for any future works.

Shaun Cairns, Royston’s operations manager, said:

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.

The Highland Chieftain is a purpose-built support vessel and is part of one of the largest fleets of OSVs in the industry. Tidewater Marine has over 60 years of experience supporting offshore energy exploration and production activities worldwide.
