Generating set, Bergen B33:45
Based on a top modern, modularised design the B33:45 range sets a new industry standard in terms of fuel efficiency, low emission and low life cycle cost.
Defined by our customers
The Bergen B33:45 diesel range carries forward the Rolls-Royce Bergen engine family into a new era. The engine platform offers 600 kW per cylinder in a compact, modularized engine design. The new engine portfolio offers industry leading energy consumption and emission figures.
The Bergen B33:45 liquid fuel engine shares many of the design features to the B36:45 gas engine series, and commonality on many engine components such as the engine block and crankshaft. This allows the flexibility to convert from diesel to gas, or vice versa, depending on our customers need.
In-line engines are offered in 6, 8 and 9 cylinder configurations, spanning a power range from 3,600 kW to 5,400 kW. The V-engine is available as 12, 16 and 20 cylinder configurations with a power range from 7,200 kW to 12,000 kW.

Engine ratings are according to ISO 3046/1. The above figures are based on conditions at maximum 45°C ambient air temperature and maximum 32°C sea water temperature. SFOC is based on MDO with a net calorific value of 42.7 MJ/kg and no engine driven pumps, at 85% engine load. At 100% engine load the SFOC will be 177 g/kWh. If engine driven pumps are attached, please add 1 g/kwh for each engine driven pump.
