The Rolls-Royce brand MTU is showing its concepts at the current SMM, Hamburg, in response to the IMO Tier III emission standard which is due to come into force in 2016. “MTU is well-prepared for IMO Tier III, be it with SCR exhaust aftertreatment systems for diesel engines or with gas engines,” explains Dr. Michael Haidinger, Chief Sales Officer at Rolls-Royce Power Systems. In an animated presentation, MTU is demonstrating the latest high-speed Series 4000 gas engine based on its trusted 4000 M63 diesel engine which is widely used in working vessels. The first field-trial engine is scheduled to go into service in 2016 in a new environmentally-compatible tugboat. MTU's natural-gas marine engine is due to be launched on the market in 2018.
