Major Overhauls Completed for Ireland's Mainport

Work to overhaul main propulsion diesel engines on a seismic support vessel operated by Irish Mainport Holdings has been completed by marine engineering and propulsion specialist Royston.

The work saw engineers from Royston carry out a major overhaul of the port and starboard Cummins QSK60 MCRS main engines onboard the 55m length MV Mainport Pine, as part of a scheduled maintenance programme of critical power systems while the vessel was docked in the Port of Sunderland.

This involved the removal of fuel injectors, turbochargers, cylinder heads, powerpack assemblies and camshafts. The engine was rebuilt utilising service exchange components, new bearings, seals and gaskets before extensive sea trails consisting of incremental load testing and alarm shut downs.

Shaun Cairns, Royston’s operations manager, said:

We’re delighted to continue to develop our relationship with Mainport, who recognise our experience with the engines and vessel types. Our commitment to delivering the highest standards of work and service ensures that vessels can return to sea going operations as swiftly and effectively as possible.

Brendan Courtney, technical superintendent at Irish Mainport Holdings, said:

As an independent service operator, Royston continues to impress with its capabilities, drawing on its professionalism, extensive experience and resourcefulness to complete the work on time and to the highest quality standards.

MV Mainport Pine is part of a current fleet of survey and research ships, seismic support vessels and tugboats owned and operated by Cork-based Irish Mainport Holdings, which is a provider of marine services to ship-owners, exporters, importers, oil companies, survey companies and offshore wind companies.
