Rolls-Royce Launches New Medium-Speed Marine Engines

On Tuesday, Rolls-Royce unveiled the first of a new family of medium-speed engines for the marine market that will include versions powered by natural gas and diesel. The new engines offer a 20 percent 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 at the SMM exhibition in Hamburg. 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. The engines are suited to numerous types of offshore vessels including anchor handlers, seismic, subsea construction vessels, semi submersibles and drill ships. The design will also suit commercial vessels such as ropax ferries, cruise, cargo ships and fishing vessels. The first B33:45 will be delivered to Norwegian customer Prestfjord Havfiske AS, for a new Rolls-Royce designed fishing vessel, in June 2015.
