Russian company was first put on hold because of security reasons, as the company is a supplier for the Norwegian navy. On March 26 The Norwegian government finalized its decision to block the sale "to ensure that the interest of national security are not threatened". Rolls-Royce subsequently re-started the sale process and on 3 August 2021, entered into an Agreement to sell the business to the British engineering and industrial group, Langley Holdings plc. The deal is scheduled to complete on 31 December 2021. Engine range The Bergen engine ranges are denoted by the letters C, B and K and are broadly divided by the power output as follows: Bergen K (discontinued) Bergen C25:33 (liquid fueled), C26:33 (gas fueled) Bergen B32:40 (liquid fueled), B35:40 (gas fueled) Bergen B33:45 (liquid fueled), B36:45 (gas fueled) for powers from 1,400 – 12,000 kW brake power. These engines can all burn Marine Diesel Oil (MDO) and heavy fuel oil (HFO) and natural gas in gas configuration. Bergen Engines AS do not have any dual fuel engines. They achieve specific fuel consumptions for liquid fuel between 183 and 196 g/kWh. Specific lubricant oil consumptions are of the order of 0.8 g/kWh for liquid fueled engine and 0.4 g/kWh for gas fueled engines. Bergen K series (discontinued) The Bergen K marine diesel and gas engines are a range of marine internal combustion engines manufactured by Rolls-Royce plc. Mechanical configuration The Bergen K lean burn marine engines with 250mm bore and 300mm stroke is available as a diesel in 6, 8 and 9 cylinder in-line configurations for propulsion and auxiliary duties. Features: Rigid crankcase minimises deformations and ensures good main bearing alignment BMEP 20-22 bar (gas engine 18bar) Power Outputs The diesel power range is from 1215-2005 kW. Also available as a gas engine for powers from 1190 – 3970 kW the Bergen K-G4 lean burn gas engine is the result of careful development based on the Bergen K. Fuels and Consumption Lub oil consumption approx 0.8g/kWh Specific fuel consumption 193-196 g/kWh (8060kJ/kWh gas) due to turbocharger design and modern fuel injection technology The lean burn principle of the K-G4 gas engines operation combines high power and high efficiency coupled with reduced exhaust emissions, and delivers a specific fuel consumption of 7990-8060kJ/kWh. Engines in service burn natural gas and also other fuels such as gas derived from landfill and from fermentation of effluents. Development Bergen lean burn
