MTU GAS ENGINES SUPPLIED FOR HYBRID SINGAPORE TUG

MTU GAS ENGINES SUPPLIED FOR HYBRID SINGAPORE TUG

Monday, January 18, 2021 

Rolls-Royce is supplying two MTU 16V 4000 M55RN gas engines to Sembcorp Marine for installation in what is said to be the worlds first LNG-hybrid powered tug, to be operated in Singapore by Jurong Marine Services, a wholly owned subsidiary of Sembcorp Marine.

The new tug, scheduled for completion later in 2021 is the first of 12 that Sembcorp Marine plans to design and build to replace the existing diesel-powered fleet between now and 2025.

Chew Xiang Yu, Head of Rolls-Royce Power Systems' commercial marine business in Asia, said: “We are very happy to be part of Sembcorp Marine’s efforts in environmental protection and adopting new green technologies in their operations. The MTU marine gas engines are part of Rolls-Royce's Green and High-Tech programme. Without exhaust gas aftertreatment, they emit no sulphur oxides only very small quantities of nitrogen oxide, and particulate mass is below the verification limit.”

This is the first LNG-hybrid tug to be powered by MTU gas engines worldwide. Designed to ABS class by LMG Marin (Norway), part of the Sembcorp Marine group, to deliver 65t bollard pull, its main propulsion system comprises twin 16-cylinder Series 4000 gas units which will provide a combined total power of 2984kW at 1600 rpm. The new gas engines are able to deliver performance comparable to a high-speed diesel engine. Equipped with multipoint fuel injection, dynamic engine control and enhanced turbocharging, the engines cater for dynamic acceleration capabilities, high power output and reduced emissions considerably below the current IMO III limits without the need for exhaust after-treatment. The LNG-hybrid propulsion system will be able to provide flexibility to cater for various operational modes and is able to switch between low emission liquefied natural gas (LNG) engines and zero-emission battery power.

Similar MTU gas engines are powering ferries operated by the Dutch shipping company Doeksen, and have been specified for a newbuild Lake Constance ferry.
