Bergen B

Components suitable for* Rolls Royce Bergen B diesel and gas engines

We supply spare parts suitable for* the following Bergen B engines: BRM, BRG, B 32:36, B 32:40, B 35:40

The Bergen B series of diesel engines was first manufactured in 1986 as an in-line version (six, eight and nine in-line configurations), before Bergen was taken over by Rolls Royce. Ten years later a V design was also manufactured. In 2005 a V12 cylinder configuration was added. In 2008 a V16 version was added to the diesel fueled engines. There is a V20 for the gas engines.

Bergen B valves, bearings










The Bergen B engines are particularly popular in the offshore industry. Access for maintenance work is straightforward. Large crankcase doors provide good access to the connecting rods and main bearings. Components are more or less consistent within this engine series.

The rigid one-piece cylinder block and crankcase is a nodular iron casting with underslung crankshaft design. Supply ducts for oil and water are cast into the block. Lubrication oil consumption is kept to 0.8g/kWh due to a specially developed piston ring pack.

The gas variant Bergen B35:40 have proven very popular with land based power generation sites.
