Gas Engines News

The main propulsion system of the Sembcorp hybrid tug comprises twin 16-cyclinder mtu Series 4000 gas units which will provide a combined total power of 2984 kilowatts. The new engines are part of Rolls-Royce's Green and High-Tech program. 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. (Photo: Rolls-Royce)

World's First LNG-hybrid Tug Will Run mtu Gas Engines

A new liquefied natural gas (LNG)-hybrid tug—said to be the world's first—will be equipped with two mtu 16V 4000 M55RN gas engines from manufacturer Rolls-Royce.The harbor tug will be built by Sembcorp Marine Integrated Yard and 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.LNG as a fuel virtually eliminates sulphur oxide emissions…

Energy Storage Systems Continue to Expand in North American Maritime Markets

North America is increasingly adopting energy storage systems (ESS) to use in combination with combustion engines or as the sole energy carrier in fully electric-powered systems.We clearly see a transition from ‘consideration’ to ‘execution’ of hybrid and all-electric maritime projects. Stakeholders want to explore how to make vessels more energy efficient and less polluting. Corvus Energy has deployed over half of the ESSs aboard vessels globally, totaling over 300 megawatt hours (MWh).In North America, Corvus has deployed 24 MWh of energy storage capacity, and there are 13 vessels under U.S.

Alfa Laval, WinGD Partner Up to Improve Engine Efficiency on Gas-run Ships

Swedish marine equipment provider Alfa Laval and Swiss engine developer WinGD, have developed a cascade exhaust gas cooling system that promises to improve the engine efficiency on ships that run on gas.The new Alfa Laval CEC-S system (cascade exhaust gas cooling system) will be incorporated into WinGD’s gas engines where it will be used for cooling and recycling purposes. "It will contribute to significantly lowering the methane slip into the atmosphere, while also improving engine efficiency thus decreasing a ship’s carbon footprint…

The Voith Schneider Propeller is ideal for autonomous and remote-controlled vessels because on the one hand the forces can be managed very logically (according to X/Y logic) and on the other hand it can allocate desired forces so quickly. Any sensor errors or errors in data processing can therefore best be compensated by the VSP. Together with partners, we have advanced the technology development to such an extent that remote-controlled tractors with VSP can be realized. Dr. Dirk Jürgens, Manage

Interview: Dr. Dirk Jürgens, Heads of R&D, Voith Turbo Marine

Dr. Dirk Jürgens heads R&D at Voith Turbo Marine, a part of the family owned Voith conglomerate which employs more than 19,000 people in 60 countries. Voith Rudderpropellers were chosen as the propulsion system for the three new Staten Island Ferry vessels, and Dr. Jürgens discusses the evolution of the system.The ‘Voith’ name is a well-known one in the maritime industry, but to start please provide an overview of the product and service you offer to the maritime industry.The…

ClassNK Grants AIP on LPG Reformer for Marine Engines

Classification Society ClassNK granted an Approval in Principle (AIP) to Osaka Gas for their joint project with Daihatsu Diesel on an LPG Reformer for marine engines. This was the first AIP granted in Japan for such equipment.The LPG Reformer is designed to convert LPG into synthetic methane gas equivalent to the kind found in LNG. Due to being mainly composed of propane and butane, LPG is susceptible to knocking (abnormal combustion), making it difficult to use as a fuel for lean burn gas engines and dual fuel engines.

Wärtsilä Rolls-out Pure Gas Marine Engine

Finnish corporation Wärtsilä has launched the 31SG pure gas engine for marine market applications.The 31SG is based on the successful Wärtsilä 31 product platform; the diesel version of the engine has been recognized by Guinness World Records as being the world’s most efficient 4-stroke diesel engine.The Wärtsilä 31SG engine further reduces the total cost of ownership and the environmental footprint for vessels operating in regions where there is a developed gas infrastructure.
