Swiss marine power company WinGD will realise the first commercial instalments of its new variable compression ratio (VCR) technology on two new dual-fuel LNG powered vessels being built for NYK Line.A 95,000 DWT bulk carrier being built at Oshima Shipbuilding and a 7,000 CEU pure car and truck carrier (PCTC) being built at Shin Kurushima Dockyard will be the first two-stroke powered vessels that can dynamically optimise combustion depending on the fuel being used – delivering improved emissions…

MAN Energy Solutions has has demonstrated its latest low-speed, dual-fuel engine—an MAN B&W ME-GA type designed for liquefied natural gas (LNG)/fuel-oil running—at a ceremony live-streamed from its Copenhagen Research Center on Thursday. The new engine is an Otto-cycle variant of the company’s ME-GI engine.As its pre-mixed combustion results in low NOx emissions, the ME-GA engine is inherently Tier II and Tier III compliant in gas-operation mode. To fully utilize its dual-fuel potential in Tier III areas…

MAN Energy Solutions announced that it will offer its proprietary EGR (Exhaust Gas Recirculation) system as an emissions solution for its new, low-speed ME-GA engine, the Otto-cycle variant of its established ME-GI dual-fuel engine. EGR is a NOx-emissions-reduction technique that ensures IMO Tier III-compliance in both diesel and gas mode.The company has long experience with the emission-reduction technology and reported the first order for an EGR system in 2011 when it was fully integrated within the MAN B&W 6S80ME-C9 main engine of a 4,500 teu containership newbuilding.Thomas S.

A snap poll recently conducted by ABS found that as many two-thirds of global shipowners had yet to select a technical pathway to meet the International Maritime Organization’s (IMO) mandatory decarbonization targets for 2030 and 2050.With the technologies supporting a myriad of new low-carbon fuels evolving at vastly different speeds, any tendencies to wait for information to mature before making significant long-term capital commitments are understandable, and pragmatic.With…

MAN Diesel & Turbo has signed a contract with Sembcorp Marine in Singapore to supply the dual-fuel propulsion system – including exhaust-gas after-treatment – for a New Semi-submersible Crane Vessel (NSCV) for Heerema Offshore Services. The scope of the contract – signed on 30 October, 2015 – provides for 12 × MAN 8L51/60DF four-stroke engines + 12 × MAN SCR (Selective Catalytic Reduction) systems. MAN Diesel & Turbo states that the total power output of the engines is some 96 MW and believes it – with the exception of power barges – to be one of the largest engine installations the world has ever seen aboard a single ship. Certainly, it is the first vessel of this size to feature dualfuel technology and, upon completion, will be the largest vessel of its kind globally.

Caterpillar Marine Power Systems announced the EPA Tier 2 Certification of all MaK engine platforms with cylinder volumes of above thirty liters. Included in the certification are the M 32 C, M 43 C, M 46 DF as well as the recently announced M 34 DF engine platform. The certification of the MaK range provides customers operating in the American market, specifically in the commercial and offshore marine markets, a spectrum of power nodes to meet emissions regulations on U.S. flagged vessels.

Caterpillar, Wärtsilä and Volvo Penta introduce new, efficient and environmentally compliant engines. A crowded market becomes even more competitive. Forget all the worries about how industry would be able to comply with the coming changes to the regulatory scheme that affects marine propulsion and related emissions. Demand has met supply and it has done so robustly and in impressive form. And, if the past month is any indication, the innovation in the market is more than keeping up. This month, we provide just a sampling of the impressive developments in marine propulsion. Clearly, workboat operators now have a cornucopia of options for the repower and newbuild market, alike.

Caterpillar Marine Power Systems announce the development of the MaK M 34 DF, a new marine dual fuel engine platform for the commercial marine industry. The M 34 DF dual fuel engine boasts a power rating of 500 kW per cylinder at 720 and 750 rpm in diesel and gas modes, and will share the same footprint as the highly successful M 32 C engine series. The M 34 DF will be capable of running on natural gas as an alternative to marine diesel oil or large and complex scrubber installations for Emission Control Areas (ECA) operation as of 2015. First engine deliveries are foreseen for October 2014.
