Rolls-Royce engines picked for world’s first LNG-hybrid tug

Rolls-Royce has been contracted to supply two mtu 16V 4000 M55RN gas engines for the world’s first LNG-hybrid powered tugboat.

The engines will be supplied to Sembcorp Marine Integrated yard, Rolls Royce said in its statement.

The harbor tug will be operated in Singapore by Jurong Marine Services, a unit of Sembcorp Marine. The new LNG-hybrid tug is the first of 12 tugs that Sembcorp Marine plans to design and build to replace the existing diesel-powered ones between now and 2025.

“The mtu marine gas engines are part of Rolls-Royce’s Green and High-Tech program. Without exhaust gas after treatment, they emit no sulfur oxides only very small quantities of nitrogen oxide, and particulate mass is below the verification limit”, says Chew Xiang Yu, head of Rolls-Royce Power Systems’ commercial marine business in Asia.

This is the first LNG-hybrid tug to be powered by mtu gas engines worldwide. Designed by LMG Marin, part of the Sembcorp Marine group, to deliver 65T Bollard Pul with ABS Class, the LNG-hybrid tug is estimated to be completed in the later part of 2021.

The main propulsion system of the tug comprises twin 16-cylinder mtu Series 4000 gas units which will provide a combined total power of 2984 kilowatts at 1600 RPM.

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.

The new mtu gas engines are already powering ferries operated by the Dutch shipping company Doeksen in the specially protected Wadden Sea.

A Lake Constance ferry operated by Stadtwerke Konstanz will also start operating in 2021 with the new mtu gas engines., Rolls-Royce said.
