Marine engineering and propulsion specialist Royston has completed engine overhaul work on board one of the world’s most advanced drill ships for Stena Drilling
Work on 228-m Stena DrillMAX saw a 48,000 running hours service on a Wartsila W16V32 engine carried out by a team of engineers in Las Palmas in the Canary Islands within a tight deadline, complicated by travel restrictions due to the pandemic.
The generator, one of six used to power thruster units and provide electricity for operations, heating, power and lighting systems, received new fuel injectors, cylinder heads and liners as part of the service package, which involved the disassemble and rebuild of the power unit in an around-the-clock operation.
The initial programme of works was expanded following a primary inspection and additional Royston engineering resources were brought in to support the original team to complete work on the crankshaft seal replacement. Work on servicing the turbocharger was also completed and saw new cartridges and gaskets fitted to ensure optimum operational performance.
Royston engineers, who also oversaw engine testing in line with the manufacturer’s specification and tolerances, remained on board Stena DrillMAX to utilise planned downtime before it sailed to the coast of Guyana, South America, where it resumed drilling activities for ExxonMobil. Completion of the contract follows other engine service work Royston has carried out on the Stena Drilling fleet.
Stena Drilling superintendent Ian Kelman said “Royston has provided excellent support and performance in difficult circumstances both logistically and technically.”
Royston operations manager Shaun Cairns said “Stena is seeing the value of outsourcing its diesel engine service and repair work to Royston, which as a single source supplier, can deliver added-value engineering resources work on time, quickly and cost effectively.”
Part of a six-strong fleet of vessels, Stena DrillMAX is a harsh environment dynamically positioned drill ship, designed for deepsea operations and capable of drilling in water of 3,000 m.
