Pure gas engines developed for green OSV operations

摘要

There are a growing number of dual-fuel engines that use both diesel and natural gas and a growing requirement to develop main propulsion engines that purely burn gas for applications including OSVs. Rolls-Royce Power Systems has developed gas-fuelled engines and generator sets for offshore support and oceangoing towage vessels. Its main product for these vessels is a new 16-cylinder pure gas engine, based on MTU's proven 16V 4000 M63 diesel engine, with a power output of 1,492 kW. Rolls-Royce Power Systems says it has also produced an eight-cylinder version with an output of 746 kW. These units would be suited to special purpose vessels, smaller OSVs, tugboats, ferries and push boats. "The dynamic acceleration behaviour and the possibility to install direct mechanical propulsion systems with fixed propellers are suitable for various commercial vessels," says Rolls-Royce Power Systems commercial marine applications engineer Cyrill Halbauer.
