DSME Win Marine Gas Engine Patent Case

Daewoo Shipbuilding & Marine Engineering Co. has won a patent suit against Cryostar SAS, a French ship parts maker, at the European Patent Office (EPO), according to Yonhap News. Yonhap explains that the HiVAR-FGSS is a device used to inject natural gas stored in a tank to a ship's engine after compressing it using high pressure. Daewoo Shipbuilding obtained the patent for the device from the EPO in May 2011, but French firm Cryostar SAS claimed that the South Korean shipbuilders' patent for HiVAR-FGSS should be nullified because it was neither worthy of a patent nor has improved features.

MHI to License KU Gas Engine Technologies to ZGPT of China

Mitsubishi Heavy Industries, Ltd. (MHI) concluded an agreement with ZGPT Diesel Heavy Industry Co., Ltd. (ZGPT), a Chinese manufacturer of stationary and marine engines, under which MHI will license its KU gas engine technologies to ZGPT. The move is targeted in the near term at seeking further penetration of the KU gas engines in the Chinese market as that market continues to mark robust growth, and beyond the near term at entering the local market for gas-fired distributed power generation system, a niche that is expected to greet sharp expansion in demand going forward.

First 2-Stroke Gas Engine Taking Quantum 1-Stroke

London: By introducing a new solution for LNG-fuelled ships, DNV and MAN Diesel & Turbo are taking the Quantum concept ship one stroke further. Both the machinery and the hull design and arrangement have been improved. A year ago, DNV launched its container ship concept – Quantum. This concept ship was designed to stir up a debate about shipping innovation. MAN Diesel & Turbo responded very positively, and over the past few months the engine manufacturer and the class society have worked closely together to move the concept one step nearer to becoming an actual ship.

Sovcomflot Pushes for LNG-fuelled Vessels

SCF Group's Sovcomflot sees bright future for LNG-fuelled vessels in the tanker industry. "LNG is a promising fuel for large-capacity vessels, which will significantly increase their environmental compatibility and efficiency," says the company. As the world’s leader in the Aframax tanker segment, Sovcomflot is pioneering the conversion of this class of vessel to LNG as a fuel. SCF Group signed a bunkering agreement with Shell for the supply of gas engine fuel for SCF’s Aframax tankers that are specially designed to run on LNG.

New MTU Engines Make Their Debut

At the international maritime exhibition Nor-Shipping in Oslo from May 30 to June 2 2017, MTU, part of Rolls-Royce Power Systems, presented its propulsion and systems portfolio, primarily for offshore supply vessels, workboats and ferries. This included Series 2000, 4000 and 8000 propulsion engines in an output range from 400 to 10,000 kW, hybrid propulsion solutions and diesel electric propulsion systems and diesel gensets for the supply of on-board power. Rolls-Royce showcased MTU’s Series 4000 diesel engine meeting IMO III and EPA Tier 4 emission regulations.

Wärtsilä Tests New Two-Stroke Dual-Fuel Gas Engine

Wärtsilä has tested its new low-speed gas engine technology in trials conducted at the company's facilities in Trieste, Italy. The tests were carried out on September 19 in conjunction with Wärtsilä's Licensees Conference in Trieste. Wärtsilä successfully demonstrated that the engine performance fully complies with the upcoming IMO Tier III nitrogen oxide (NOx) limits, thereby setting a new benchmark for low-speed engines running on gas. The new RTX5 2-stroke test engine is part of Wärtsilä's 2-stroke dual-fuel gas engine technology development programme.

CMR Debuts Gas Engine Pressure Regulator

A range of gas engine pressure regulators, which provide control of pressure levels within the fuel train on dual fuel or natural gas engines, is new for control and instrumentation specialists CMR Group. CMR’s regulators enable high-pressure gas fuel from lines and tanks to be reduced to safe and/or usable pressures for the secure and reliable operation of high horsepower engine technology used in a wide range of harsh and challenging environments including the onshore/offshore oil and gas industry.

Lake Constance Ferry to Test MTU Gas Engine

From 2019, Rolls-Royce Power Systems and the City of Constance public utility are to begin testing the marine propulsion technology of the future on Lake Constance. This takes the form of a gas engine carrying the MTU brand. The public utility's new car ferry is to be equipped with twin eight-cylinder Series 4000 gas engines from MTU, each delivering 746 kW. This makes it the first inland waterway passenger vessel in Europe to be propelled by straightforward high-speed gas engines. The fuel will be liquefied natural gas.

Diesel Gas Engine Prototypes to be Built in Asia

The partnership is to carry out full-scale demonstrations of the ME-GI principle based on the temporary conversion of existing production engines to ME-GI units. Accordingly, Hyundai intends to convert an 8S70ME-GI unit later this year, while Mitsui will convert a 6S70ME-GI unit mid-2013. The ME-GI engine is a gas-injection, dual-fuel, low-speed diesel engine that, when acting as main propulsion in LNG carriers or any other type of merchant marine vessel, can burn gas or fuel-oil at any ratio, depending on the energy source available on board and dictated by relative cost and owner preference.
