Bergen B36:45V generating set

Choose Rolls-Royce Bergen engines for 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.

MARINE GAS 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 yards:

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

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 optimised fuel/air ratio at varying ambient conditions for lean-burn operationg ambient conditions for lean-burn operation

  • The performance data is based on: Marine gas engine ratings are according to ISO 3046-1, at maximum 45°C ambient air temperature and maximum 32°C sea water temperature. Specific fuel gas consumption given at 100% load and no engine driven pumps, running on natural gas with Methane number above 70 and net calorific value of 36 MJ/nm3. To include 3 engine driven pumps, add 1.3% for each pump. Gas feed temperature is 20-40°C. Minimum gas feed pressure to Gas Regulating Unit to be 5,5 barg.
  • Waste heat recovery: Necessary data for arranging waste heat recovery plants (exhaust gas and cooling water) are available upon request.
  • Note: Due to continuous development, some data may be changed without notice.
