ENGINE OVERHAUL ON DRILL SHIP CONCLUDED AT SEA

A five-strong team of Royston engineers carried out a 48,000-hour overhaul on a Wartsila W16V16 diesel generator onboard the 228m drillship, as part of a planned maintenance programme. The job was completed while the ship sailed from the Caribbean to a position off the Guyana coast, where it is currently carrying out drilling operations.

This saw the replacement of parts where necessary as part of a 48,000hr service. This included inspection and refurbishment work on the crankshaft main and thrust bearings, main bearing jacks, connecting rods, piston rings, crowns and skirts, along with the installation of new big end bearing shells.

Royston engineers also completed the replacement of OEM overhauled turbocharger cartridges and repairs to the turbocharger exhaust manifold, carried out upgrades to intermediate gears, camshaft gears, and the speed governor. Following completion of the work, the generator was fully checked and tested to ensure maximum operational capacity.

Built in 2008, the Stena Carron is one of six vessels in the Stena Drilling fleet and is a sixth-generation harsh environment, multi-purpose dynamically positioned drillship, capable of drilling to depths up to 3,000m. It has managed pressure drilling capabilities, a wireless unit tower and enhanced drilling fluid storage.
