About Bergen Engines
Bergen Engines AS is a Norwegian manufacturer of medium-speed reciprocating engines based in Bergen. The company traces its origins to 1855 and built its first diesel engine in 1946. It has produced more than 7,000 engines, about half of which are still in operation. Rolls-Royce sold the business to the British industrial group Langley Holdings in December 2021.
The marine range covers liquid-fuel engines (B33:45L/V and C25:33L) and lean-burn natural gas engines (B36:45L/V and C26:33L), spanning roughly 1.4 MW to 9.6 MW. The engines are used for direct mechanical propulsion and as generating sets in cruise ships and ferries, offshore vessels, fishing and aquaculture vessels (nearly 200 engines supplied), tugs and workboats, cargo ships and naval vessels, including the Royal Norwegian Navy. Bergen says its liquid-fuel B33:45 platform can be converted to gas operation through its B3X platform.
The same engine families are sold for land-based power generation, where the B35:40V gas engine is also offered.
