Royston completes engine overhaul work on drill ship

Marine engineering and propulsion specialist Royston has assisted in the overhaul of diesel power plant on-board one of Europe’s largest drilling ships as it sailed while on passage.

A five-strong team of Royston engineers undertook the 48 000-hour overhaul of a Wartsila W16V16 diesel generator onboard the 228 m length Stena Carron, as part of a planned maintenance programme.

The job was completed as 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 48 000 hour 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.

Fraser Scott, engineering superintendent at Stena Drilling, said: “Royston has completed another quality job for us during these challenging times. It reflects the experience and expertise they bring to their work, going over and above expectations in support of our vessel fleet operations and maintenance.”

Shaun Cairns, Royston’s operations manager on the contract, said: “This latest project for Stena Drilling shows that regardless of a vessel’s location in the world, and the status of its engines, we have the flexibility and resources to respond rapidly with a highly skilled and efficient engineering team.”

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 10 000 ft. It has managed pressure drilling capabilities, a wireless unit tower and enhanced drilling fluid storage.
