Bergen Engines has been a trusted supplier of engines and generating sets to the offshore market since the early seventies. The engines’ robustness and high reliability have made them a preferred choice for the harsh environments surrounding offshore installations across the globe.

Bergen Engines has an impressive track record within offshore deliveries, supplying engines and generating sets to Platform Supply Vessels (PSV), Anchor Handling Tug Supply vessels (AHTS), drilling rigs, accommodation rigs and seismic vessels.

As the world is transitioning towards renewable alternatives to fossil fuels, we are bringing our extensive offshore experience with us to the wind turbine segment, powering offshore wind turbine installation vessels.

Reference Projects

The first offshore vessel to run on biofuel

Island Crusader is the first offshore vessel on the Norwegian shelf running on biofuel, resulting in immediate and significant reductions in CO2 emissions. This pilot, run by Lundin Energy Norway, also proves that biogas can be used on Bergen gas engines without any modifications at all. The vessel is equipped with two Bergen C25:33L6A MDO and two Bergen C26:33L9A gas engines.

Engines for wind turbine installation vessel built at Keppel AmFELS

Six Bergen B33:34L8A diesel engines will be powering the new wind turbine installation vessel to be built at the Keppel AmFELS yard for the U.S.-based energy provider Dominion Energy. The vessel is destined to be among the largest of its type, capable of transporting and installing current- and future-generation wind turbines and foundations.

Medium speed marine gas engines

Our natural gas fuelled marine engines offer exceptionally low emissions of NOx, CO2, SOx and particulates. Innovative technologies like variable valve timing, individual cylinder pressure monitoring and variable turbo geometry ensure optimized and efficient operation.
