The new engines reportedly offer a 20 per cent increase in power per cylinder, while reducing fuel consumption, emissions and through-life operating costs compared to existing engines in the Rolls-Royce Bergen range.
The first engine, the B33:45 powered by diesel, was officially launched in September at the SMM exhibition in Hamburg, the maritime industry’s largest event of the year.
Mikael Makinen, Rolls-Royce President-Marine said: “Shipowners want better performance at a lower price and society wants cleaner oceans.
“We have been developing this engine over the past three years, and part of its future success will be down to the excellent collaboration and sharing of engine technology between our experts in Bergen, Norway and Friedrichshafen, Germany.“
Rolls-Royce said the 20 per cent increase in power per cylinder, compared to the current B32:40- series engines, means the same power demand can be met with fewer cylinders. This will give significantly lower maintenance costs and will be more compact where engine room space is at a premium.
Thor Humerfelt, the company’s programme director for Bergen engines, said: “Our overall design goal was to develop an engine that offers reduced life cycle costs. Engines are one of the large contributors to a ship’s operating and maintenance costs, so we believe that the features of this family of engines will prove popular as we expand the range.”
The B33:45 will follow a modular design for ease of production and maintenance. The in-line engine platform will consist of 6, 7, 8 and 9-cylinder variants spanning a power range from 3,600kW to 5,400kW.
