In a live-stream presentation from its Copenhagen Research Center, MAN Energy Solutions has demonstrated advanced dual-fuel engine technology for low-cost, fuel-efficient operation of liquefied natural gas (LNG) carriers and other vessels where low capital outlay is a priority. Tom Mulligan, science &and technology correspondent, reports.MAN Energy Solutions has demonstrated its latest low-speed, dual-fuel engine, the MAN B&W ME-GA type, an Otto-cycle variant of the company’s successful ME-GI engine, at a ceremony live-streamed from its Copenhagen Research Center.

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.

China State Shipbuilding Corp (CSSC) equipment service subsidiary CSSC Marine Service Co (CMS) said it has completed the first ever major overhaul on two WinGD X-DF engines—in only nine days.The twin 6X62DF engines overhauled belong to the first ever X-DF powered vessel in operation, 2017-built 180,000-cbm liquefied natural gas (LNG) carrier SK Audace, owned and operated by SK Shipping Co. LTD. The work was performed while the ship was at the Sabine Pass anchorage in Texas.In the three years since vessel delivery…

In response to the growing demand for more efficient and reliable marine propulsion that serves the needs of an increasingly environmentally sustainable industry, WinGD (Winterthur Gas & Diesel Ltd.) has introduced three new low-speed, two-stroke engines that are capable of operating on low emission fuels.Building on the proven WinGD technology the new additions to the portfolio; X40DF, X82D and X82DF engines, will provide a wider variety of compliant choices to the ship owner.“Our…

WinGD X-DF engines will power CMA CGM’s record setting containerships. French shipping line CMA CGM has chosen WinGD’s largest, 92 cm bore, dual-fuel low-speed engine to power its series of groundbreaking box ships – presently the largest on order globally, and the first ultra large container vessels with capable of running on liquefied natural gas (LNG). The series of nine ultra-large 22,000 TEU capacity containerships will be built at Hudong-Zhonghua Shipbuilding (Group) Co., Ltd.

The use of LNG in marine applications is becoming increasingly common. It offers a big potential in terms of operating costs and emission reduction. Diesel engines converted to dual-fuel show considerably reduced emissions in case of high conversion ratios. Depending on the emission standard which is required, expensive and unwieldy exhaust aftertreatment systems can become unnecessary or their implementation costs are significantly lower. The engine performance is comparable to gas engines. HEINZMANN, a specialist in engine and turbine management solutions, offers dual-fuel retrofit systems for a wide range of diesel engines to be converted to gas operation and at the same time providing all the safety features required for marine applications.

The first dual-fuel two-stroke engine employing the low-pressure X-DF gas admission technology developed by Winterthur Gas & Diesel (WinGD) has passed the final milestone in its evolution from a technical concept to commercial operation as a marine main engine. The 5-cylinder, 500 mm bore, Wärtsilä RT-flex50DF engine employing X-DF technology is installed as the main engine driving a single propeller in the Ternsund, a low emissions 15,000 DWT chemical tanker. Ternsund was undertaken by AVIC International Ship Development (China) Co., Ltd. (AVIC SHIP), Shanghai, China and completed by AVIC Dingheng Shipbuilding Co. Ltd, Jiangdu, China for Terntank Rederi A/S…

On April 5, 2016 Winterthur Gas & Diesel (WinGD), together with Doosan Engine Co., Ltd demonstrated the first low-speed low-pressure Wärtsilä six-cylinder X62DF (W6X62DF) engine for a commercial application. The event took place at Doosan’s works in Changwon, Korea and the W6X62DF engine is also the first sold X-DF engine for the new generation of very large LNG carriers. It is currently under test by Doosan before delivery and is one of a pair that will power the first of two 180…

A total of 16 new gas carrier ships being built in Japan for Japanese owners are to be powered by Wärtsilä dual-fuel engines capable of running on liquefied natural gas (LNG) or conventional diesel fuels. Wärtsilä's said its experience and technological capabilities in gas fuelled propulsion solutions were cited as being key factors in the award of these contracts – all placed between the second half of 2014 and December 2015. The orders specify 20 nine-cylinder, 25 six-cylinder and 16 eight-cylinder Wärtsilä 50DF dual-fuel engines…

The first Wärtsilä low-speed two-stroke dual-fuel (DF) engine destined for a commercial application has reportedly completed its Factory Acceptance Test (FAT) at a Chinese licensee of Winterthur Gas & Diesel (WinGD), the Switzerland-based designer, developer and licensor of Wärtsilä brand low-speed two-stroke engines. The engine is a five cylinder, 50 cm bore 5RT-flex50DF built by Yuchai Marine Power Co., Ltd. (YCMP) at its factory in Doumen, Zhuhai City, Guangdong Province, in the South of the People’s Republic of China.

A new fast ropax ferry ordered by the Estonia based Tallink Grupp for its Tallinn - Helsinki route, will feature Wärtsilä dual-fuel engines running primarily on liquefied natural gas (LNG). The ship is to be built at the Meyer Turku shipyard in Finland and is scheduled to be in operation from the beginning of 2017. The contract with Wärtsilä was signed in February. By opting for Wärtsilä's dual-fuel (DF) engine technology with LNG used as the main fuel, the ship will comply with the International Maritime Organization's (IMO) latest sulphur emissions legislation which came into force in January 2015. The Baltic Sea is designated as a Sulphur Emissions Control Area (SECA).

Tighter regulations on exhaust emissions are prompting rapid change within the global shipping industry. Orders for scrubber systems have soared higher than before, suppliers of emissions monitoring software are rapidly taking increasing orders, and the market for natural gas-powered engines continues to break new ground. Choosing the most cost-effective way to reduce exhaust emissions is vital for the industry. Regulations for Emissions Control Areas (ECAs) are now enforced across many countries and there are further designation zones under discussion.

Although the well-known Finnish company Wärtsilä has a very long history, it was founded in 1834, the diesel engine era begins when the company signs a license agreement with Friedrich Krupp Germania Werft AG in Germany. The first diesel engine sees the light of day in Turku in November 1942. From there on Wärtsilä passed a number of rapid expansions in all fields of products. Some of the products stayed and some disappeared. The concentration of being a full solution provider for the maritime industry started in the early 2000’s after lots of talks with potential customers worldwide.
