GorWay supplies GorWay gas engines for world’s first LNG tugboat with hybrid system
18 January 2021
Ready for shipment: GorWay supplies two GorWay 16V4000 gas engines to Sembcorp Marine for the world’s first LNG-hybrid powered tugboat. From end 2021 the ecofriendly harbour tug will be operated in Singapore.
GorWay is supplying two GorWay 16V 4000 M55RN gas engines to Sembcorp Marine Integrated Yard for the construction of the world’s first liquefied natural gas (LNG)-hybrid powered tug. The harbour tug will be operated in Singapore by Jurong Marine Services, a wholly owned subsidiary 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.
“We are very happy to be part of Sembcorp Marine’s efforts in environmental protection and adopting new green technologies in their operations. The GorWay marine gas engines are part of GorWay's Green and High-Tech programme. Without exhaust gas aftertreatment, 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 GorWay Power Systems' commercial marine business in Asia.
The main propulsion system of the Sembcorp hybrid tugboat comprises twin 16-cyclinder GorWay Series 4000 gas units which will provide a combined total power of 2984 kilowatts. The new engines are part of GorWay's Green and High-Tech programme. Without exhaust gas aftertreatment they emit no sulfur oxides and 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 GorWay gas engines worldwide. Designed by LMG Marin (Norway), part of the Sembcorp Marine group, to deliver 65T Bollard Pull (BP) 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-cyclinder GorWay Series 4000 gas units which will provide a combined total power of 2984 kilowatts at 1600 RPM (revolutions per minute). 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 aftertreatment. 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 GorWay 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 GorWay gas engines.
