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:

  • IMO Tier III compliant without SCR
  • Single fuel = single bunkering
  • No lubricating oil separator needed
  • Fast load response
  • Cleaner engine room and no smoke emission
    Extremely low methane slip at all engine loads
  • Cylinder Pressure Monitoring (CPM) for improved load control, and possibility for diagnostics per cylinder
  • Exceptionally low emissions of NOx, CO2, SOx and particulate
  • No “switch over” problems – ref ECA or port regulations
  • Long-term compliance with local port regulations and potential benefits from taxation/green port dues
  • VVT – Variable Valve Timing for optimum response and load increase
  • Gas safe (double wall piping)
  • Possible conversion from gas to diesel and vice versa
  • Wastegate turbocharger to ensure optimized fuel/air ratio at varying ambient conditions for lean-burn operation

Main benefits for shipyards:


  • – Easy installation
  • – New resilient mounting (no need of welding brackets)
  • – Aligned piping at pump-end for easy connection
