 It has been suggested that Rolls-Royce Bergen K series and Rolls-Royce Bergen B series be merged into this article or section. (Discuss)

Rolls-Royce Marine Diesel Engines are manufactured by Rolls-Royce plc and cover five ranges of diesel engines for the marine sector. There are three "Bergen" and two Crossley Pielstick ranges with power outputs in the range 1.2MW to 15MW.

[edit] Bergen Range

The Bergen marine diesel ranges are denoted by the letters C,B and K and are broadly divided by the power output as follows:

  • Bergen K,
  • Bergen C and;
  • Bergen B32:40

for powers from 1200 – 8,000kW,

  • Bergen KG 4.2 and;
  • Bergen B35:40

for powers of 1190kW – 8750kW.

These engines can all burn Marine Diesel Oil (MDO) and Heavy Fuel Oil (HFO).

They achieve specific fuel consumptions of between 183 and 196g/kWh. Specific lubricant oil consumptions are of the order of 0.8g/kWh.

Two of the Bergen marine engine variants may be fuelled by natural gas.

[edit] Bergen K-G4

Also available as a gas engine for powers from 1190 – 3970kW the Bergen K-G4 lean burn gas engine is the result of development based on the K type diesel and heavy fuel oil engine parent.

[edit] Bergen B35:40

The Bergen B35:40 gas engine has high power and efficiency in the 720-750 rpm class and, is designed for low emissions of NOx, CO, and UHC combined. It builds on the latest B diesel hardware, specifically redesigned and modified for this gas variant.

[edit] Crossley Pielstick range.

Pielstick PA6 STC and PA6B STC

Manufactured under licence by Rolls-Royce plc, these engines are designed and developed specifically to burn heavy residual fuels. the Pielstick PA range of diesels offers cylinder configurations ranging from 6 to 20 and a power range of 1950 to 8910kW.

S.E.M.T Pielstick PC2.6 & PC2.6B These models are rated for Naval applications to run at 520/600 rpm respectively with power outputs in the 6 to 15 MW range.
