B36:45V

Natural Gas | Medium Speed Propulsion Engine and Generating Set
7 200 - 9 600 kW

Marine natural gas engine designed for cost-effective operation.

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.

About the data 

Remote monitoring

A single Bergen medium-speed engine can have more than 200 sensors transmitting a vast amount of data that measures all aspects of an engine’s health and performance at any given moment.

Data analytics, A.I and deep learning combine to give you real-time insights into your equipment using our Equipment Health Monitoring system (EHM).
