<\/p>\nRolls-Royce is supplying two 16V 4000 M55RN mtu gas engines to Sembcorp Marine Integrated Yard for the construction of the world's first LNG (liquefied natural gas) hybrid-powered tugboat. The harbour tug will be operated in Singapore. The new LNG hybrid tug is the first of 12 tugs that Sembcorp Marine plans to build to replace the existing diesel-powered tugs in the years leading up to 2025.<\/p>\n

This is the world's first LNG hybrid tug powered by mtu gas engines. The LNG hybrid tug was designed by LMG Marin (Norway), part of the Sembcorp Marine Group, for the delivery of 65 tonnes of ABS-class bollard pull and is expected to be completed later in 2021. The tug's main propulsion system consists of two 16-cylinder mtu Series 4000 gas engines, which together will deliver a total power output of 2,984 kilowatts at 1,600 revolutions per minute (rpm). The new gas engines are capable of delivering comparable performance to a high-speed diesel engine. Equipped with multi-point fuel injection, dynamic engine control and improved turbocharging, the engines ensure dynamic acceleration, high performance and reduced emissions that are well below the current IMO III limits without the need for exhaust gas aftertreatment. The LNG hybrid propulsion system will be able to respond flexibly to different operating modes and switch between low-emission LNG engines and emission-free battery power.<\/p>\n
The new mtu gas engines are already powering ferries operated by Dutch shipping company Doeksen in the specially protected Wadden Sea. A Lake Constance ferry operated by Stadtwerke Konstanz will also start operating with the new mtu gas engines in 2021.<\/p>\n
