7 engine overhaul keeps drill ship operational with no down time

HiMSEN 9L 32/40 & 18V 32/40 8,000 hour engine overhauls in the Gulf of Mexico

A major offshore drilling operator contracted Goltens Houston , to provide complete service maintenance and supervision for the 8,000-hour overhauls on 7 of the Mobile Offshore Drilling Unit’s Hyundai HiMSEN engines. Six inline 9L32/40 engines and two 18V 32/40 engines power the drill ship.

As minimizing downtime is critical for any offshore drilling vessel, Goltens mobilized its offshore-certified diesel technicians to work in 12-hour shifts. Goltens’ service engineers worked efficiently, with the support of the ship’s crew, to complete the maintenance on each engine and restore it to operation before moving on to the next engine to provide maximum power availability to the vessel and allow it to operate without interruption.
