Engineers undertook the DG1 and DG3 24 000 and DG4 36 000 running hours service on the generator engines on-board the 113 m long vessel at A&P Tyne’s facilities in the North East of England, as part of a comprehensive refurbishment and maintenance programme of critical power units.
The 1999-built Polaris is part of Rever Offshore’s fleet consisting of specialist OSVs, which provide dive support, light construction, subsea maintenance among other critical offshore services in the North Sea sector.
The work by Royston covered the disassembly of the Wartsila W9L26 No.1 and No.3 diesel generators to fully refurbish cylinder heads, renew cylinder liner seals and overhaul pistons and connecting rods. Engineers completed deflection and bearing checks on the engines, while the fuel injection pumps were serviced, leak checked and dynamically tested and calibrated to specification.
The overhaul of Napier turbo chargers was also completed as part of the scheduled maintenance programme.
Following completion of the work, load testing in line with customer requirements and the engine manufacturer’s specification was completed by the Royston team alongside at A&P shipyard.
Royston’s service manager, Shawn Doering, said: “We’re pleased to support Rever Offshore with this significant engine overhaul programme. We applied all of our engineering skills and experience to completing the contract on time, securing cost efficiencies within a tight timescale in the process.
“Significant savings can be achieved by using independent service providers like Royston, without compromising on the quality and standard of engineering work provided.”
Based in Aberdeen since 2003, Rever Offshore, recently re-branded from Bibby Offshore Ltd, provides subsea construction/IRM and offshore operational and maintenance support and services to the UK oil and gas industry.
