Bergen Engines

What Bergen Engines does

Bergen Engines AS is a Norwegian manufacturer of medium-speed reciprocating engines and generator sets for marine and land-based power generation, headquartered in Bergen, Norway, with production facilities in Norway, Italy, and Germany. Its core product portfolio spans the B33:45, B35:40, B36:45, C25:33, and C26:33 engine families, sold as bare engines, complete gensets paired with Marelli Motori alternators, and modular power plants; the company pioneered the world's first lean-burn natural gas engine in 1991, with the same design still in operation over 30 years later, and is now commercializing variants for AI data center behind-the-meter power. Revenue is generated through three streams: (i) hardware sales of engines and gensets under custom unit pricing tied to configuration and capacity, (ii) recurring aftermarket services including Long-Term Service Agreements (LTSAs), the Worldwide Exchange Pool (WEP), spare parts logistics, operator training, and upgrades, and (iii) turn-key microgrid and modular power plant solutions delivered in partnership with sister companies Marelli Motori and Piller Power Systems under the Langley Holdings Power Solutions Division.

The company sells to enterprise customers across three primary segments: marine commercial and naval (cruise, ferries, offshore, naval, tugs, workboats), land-based power generation (utilities, mining, CHP, hybrid microgrids), and rapidly emerging AI data center infrastructure — the latter anchored by a 750MW agreement with Crusoe in June 2026 and over 3GW of BTM power deals signed within the first year of market entry. Distribution is direct and global, with regional sales managers and field sales coverage across the Americas, Europe, Asia, Africa, the Middle East, and Oceania, supplemented by service centers in key regions such as Querétaro, Mexico. The company is privately held by UK-based Langley Holdings plc following the December 2021 acquisition from Rolls-Royce and is ISO 9001/14001/45001 certified with DNV-certified compliance to Poland's grid code for synchronous power generating modules.
