Pure Gas Engine News

Wärtsilä introduced its new Wärtsilä 25 medium-speed four-stroke engine based on its modular technology platform and designed to accelerate and support the maritime sector’s efforts in achieving decarbonized operations.The engine is already capable of operating on diesel, liquefied natural gas (LNG), or on either gas or liquid carbon-neutral biofuels, and can easily be upgraded to operate with future carbon-free fuels as they become available. The flexibility of having different valve timing options is a key enabler for future fuels and emissions optimization…

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. The commercial launch of the Wärtsilä 31SG takes place in September at the Gastech 2019 conference and exhibition being held in Houston, Texas, as well as at the Neva St.

The first two preproduction units of the new mobile MTU gas engine from Rolls-Royce have completed performance tests and were accepted by the customer at the beginning of December. MTU delivered the first two of a total of four 16-cylinder Series 4000 gas engines, each with an output of 1,492 kW, for two new catamarans. From 2018, the two aluminum vessels will operate ferry services on the Dutch Wadden Sea. They are currently being built by Strategic Marine’s shipyard in Vietnam for the Dutch shipping company Doeksen.

MTU’s new gas engine for commercial marine applications – the first from Rolls-Royce – has undergone some 3,000 hours on the test bench and is now ready to enter series production as the first high-speed pure-gas marine engine. “We can now confirm that the engine meets both our requirements and those of our customers: its performance and its acceleration behavior are similar to the excellent characteristics of a diesel engine,” said Dr. Ulrich Dohle, CEO of Rolls-Royce Power Systems AG.

Bergen Tankers’ 95-meter-long chemical and product tanker Bergen Viking has returned to service following its conversion from diesel-electric to liquefied natural gas (LNG)-electric propulsion. Delivered in 2007, the Rolls-Royce powered vessel supplies diesel and petrol along the Norwegian coastline in trade for Statoil as part of a fleet of six vessels owned by Bergen Tankers AS. Bergen Viking’s retrofit saw four of the ship’s original six diesel generating sets replaced with two Rolls-Royce Bergen C6 generating sets.

Rolls-Royce has signed a collaboration agreement with Spanish energy company Gas Natural Fenosa to develop and install a pure-gas Bergen engine aboard the Baleària-operated ferry Abel Matutes. According to Rolls-Royce , the contract gives the company its first reference for a pure-gas engine installation on a European-flagged ferry operating outside of Norwegian waters. The 29,670 metric ton ROPAX ferry, delivered in 2010 from the Hijos de J Barreras shipyard in Vigo, Spain, will use an LNG-fuelled Rolls-Royce Bergen C26:33 L6 AG auxiliary engine to generate 1…

Three leading companies have teamed up to bring the first ever Reverse Stern Drive (RSD) Compressed Natural Gas (CNG) tug to the market. Damen Shipyards of the Netherlands, German engine manufacturer MTU Friedrichshafen, a subsidiary of Rolls-Royce Power Systems, and Denmark’s SVITZER have embarked on the pioneering project with the official launch of the new eco-friendly tug planned for 2016. The new RSD CNG tug combines high power with lower fuel costs and a substantial reduction in emissions. Martijn Smit, Damen Sales Manager Europe, says: “Damen is proud to be building the prototype. With the MTU 4000 engine, this vessel is excellent for ship handling, with very quick acceleration.

Dutch-based Peters Shipyards introduces revolutionary Inland Shipping concept. Planned, developed and built by Dutch Peters Shipyards, located in Kampen, a unique inland tanker is now the world’s first river vessel driven by combustion engines consuming purely natural gas. In April, the innovative new vessel was handed over to its time charterer, Shell Netherlands, who will operate the “MTS Greenstream,” via Interstream Barging, between the Netherlands and Germany; primarily on the river Rhine.
