Three main engine overhauls for SCF Swire Pacific Offshore in Russia

Bergen B32:40 L9A main engine overhauls for 3 highly specialized offshore vessels on voyage in Russia

Goltens Singapore was contracted by SCF Swire Pacific Offshore to complete overhauls on 3 state-of-the-art “E- Class” Icebreaking Platform Supply Vessels the Pacific Endeavor, Pacific Endurance and Pacific Enterprise.

The three sister vessels are each powered by four 4,320 kW Bergen B32:40L9A main engines that power the vessels’ main propulsion thrusters. Goltens was asked to perform a planned maintenance overhaul on one of these engines on each vessel.

With the vessels on assignment in Russian waters, Goltens deployed its diesel specialists to the vessels and completed the overhauls while the vessels remained in service.
