Cost-effective operation
The Bergen B-series is based on a modular design, which gives a flexible platform and at the same time carries forward the Bergen traditional values as a robust and reliable engine.

The selection of technology was done after consulting a broad range of operators, designers and shipbuilders, to establish the qualities they prize in an engine. This engine series was first introduced to the market in 2014 as a diesel engine, and the gas version followed in 2018. It is available in several in-line or Vee cylinder variants for both diesel and gas, and is equally suitable for mechanical transmission or as a marine generating set.

Main benefits for ship owners:

  • Reliable power with proven low life cycle costs
  • IMO Tier II compliant without use of SCR & IMO Tier III compliant with use of SCR
  • Dynamic service intervals with 25.000 hours between main services when operating within a defined load window
    Fast load response
  • Low vibration/structural noise level
  • Full equipment health monitoring and 24/7 support by global service network
  • Compact and modular design with a low weight construction
  • Possible conversion from diesel to gas and vice versa
  • New flexible mounts without welded brackets
  • Aligned piping at pump end for ease of connection
  • Flexible exhaust routing – 15 degree rotation of connections to turbocharger
  • Full power can be taken from either end of crankshaft up to and including V12 version

Main benefits for shipyards:


  • – Easy installation
  • – New resilient mounting (no need of welding brackets)
  • – Aligned piping at pump-end for easy connection
  • – Flexible exhaust routing (and air ducting if applicable): 15 degree rotation of connection points to turbocharger available
