新加坡首艘LNG混动拖船使用劳斯莱斯发动机

    中国石化新闻网讯 据1月19日Natural Gas World报道，1月18日，劳斯莱斯（Rolls-Royce）公司表示，该公司将向胜科海事公司(Sembcorp Marine)提供了两台燃气发动机，用于建造新加坡首个液化天然气混合动力拖船。该船只将由胜科海事的全资子公司裕廊海事服务公司在新加坡运营。

    劳斯莱斯表示，胜科海事计划设计和建造12艘液化天然气混动拖船，以取代现有的柴油动力拖船，这第一艘新型的LNG混动拖船预计将于今年年末完工。

    劳斯莱斯动力系统亚洲商用船舶业务主管Chew Xiang Yu表示，MTU船用燃气发动机是劳斯莱斯绿色高科技项目的一部分。该发动机排出的废弃，即便没有经过处理，也只会排放极少量氮氧化物，且不会排放二氧化硫，固体颗粒物也满足排放规定。”

    据劳斯莱斯介绍，这是世界上第一艘由MTU燃气发动机驱动的LNG混动拖船。拖船的主推进系统由一对16缸MTU4000系列装置组成，在1600转/分钟时，总功率达2984千瓦。

    劳斯莱斯表示，新型MTU燃气发动机已经为荷兰Doeksen航运公司在受特别保护的瓦登海运营的渡轮提供动力。Stadtwerke Konstanz运营的康士坦茨湖渡轮也将于2021年开始运营，使用的是新型MTU燃气发动机。

    ROLLS ROYCE ENGINES TO POWER SINGAPORE'S 1ST LNG-HYBRID TUG

    Rolls-Royce will supply two gas engines to Sembcorp Marine Integrated Yard for the construction of Singapore’s first LNG-hybrid powered tug, the company said on January 18.

    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, Rolls Royce said. The tug is expected to be completed later this year.

    “The mtu marine gas engines are part of Rolls-Royce's green and high-tech programme. Without exhaust gas after-treatment, they emit no sulphur oxides only very small quantities of nitrogen oxide, and particulate mass is below the verification limit,” said Chew Xiang Yu, head of Rolls-Royce Power Systems' commercial marine business in Asia.

    According to Rolls Royce, this is the first LNG-hybrid tug to be powered by mtu gas engines worldwide. The main propulsion system of the tug comprises twin 16-cyclinder mtu Series 4000 gas units providing a combined total power of 2,984 kw at 1600 rpm.

    The new mtu gas engines are already powering ferries operated by the Dutch shipping company Doeksen in the specially protected Wadden Sea, Rolls Royce said. A Lake Constance ferry operated by Stadtwerke Konstanz will also start operating in 2021 with the new mtu gas engines.
