Bergen Engines AS builds medium-speed liquid and gas fuelled reciprocating engines for marine and land-based applications worldwide.

On land and at sea, our engines can be found operating in some of the most demanding and hostile environments on earth.

Established in 1855, we built our first diesel engine in 1946 and by 1991 pioneered the very first natural gas engines. Today we are developing our engines for the next generation of fuels in readiness for the energy transition.

Of the more than 7,000 iconic Bergen engines built to date, around half are still in service today. Such is the quality and reliability of a “Bergen” engine.

Not only do we build the finest medium speed engines available, we also assemble and test complete generator sets, design modular power plants and partner to provide turn-key microgrid power solutions.

Formerly Rolls-Royce Bergen Engines AS since 1999, the company was acquired by the British engineering and industrial group Langley Holdings from Rolls-Royce on 31 December, 2021.
