The Bergen C25:33 family, launched in 2002, is one of the most compact and powerful 250mm bore engines in the world, delivering 330kW per cylinder.
The engine exploits more than 60 years experience in the 250mm bore segment, and is based on modular design to deliver a truly modern engine that is compliant with IMO Tier 2 emissions regulations.
It has a track record of very low life cycle costs and is designed for long service intervals. The engine is also simple to maintain. The liner, piston, (Inc upper con rod) and cylinder head can be replaced as a single unit, without disturbing the big end bearing, saving users a lot of time and money.
The C25:33 has been very successful in all marine applications operating on Marine Diesel Oil (MDO) and Heavy Fuel Oil (HFO). 6, 8 and 9 cylinder versions are available with powers from 1,440 to 3,000kW.
The Bergen C25:33 engine has been further developed to produce the Bergen C26:33 Gas and is now available in powers from 1,460 to 2,430kW.
