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 LNG or conventional diesel fuels.

 MAN Diesel & Turbo SE (MAN) announced that it has signed an agreement with Wessels Reederei GmbH & Co. KG (Wessels Reederei) for the conversion of the shipping company's 1,000 TEU container ship Wes Amelie to LNG capable dual-fuel operation.MAN claims that vessel's retrofit of the 8L48/60B main engine is '' the first such retrofit to be performed on a containership in the world.'' MAN also states that through running on LNG, the Wes Amelie will drastically reduce emissions of sulphur oxide by over 99%, nitrogen oxide by approximately 90%, and carbon dioxide by up to 20%.Due to the long delivery time of LNG tanks, the engine retrofit will commence in Q4 2016. Full operational usage of LNG as fuel is planned for early December, 2016.Dr. Thomas Spindler, Head of Upgrades & Retrofits – MAN PrimeServ Four-Stroke – MAN Diesel & Turbo, said: “We are very excited about the signing of this contract and view its potential for broader adoption within the maritime sector as significant. We enjoy an excellent cooperation with Wessels and commend their willingness to adopt our dual-fuel technology.”Wessels has earlier stated that the project will promote the demand for LNG as a fuel within the maritime industry ...

 To convert its vessel Coral Anthelia to dual fuel operation, Anthony Veder worked with Cat dealer Bolier to complete the industry’s first in-hull retrofitThe conversion took place aboard the Coral Anthelia, a carrier vessel that transports ethylene and liquid natural gas (LNG) primarily in northwestern Europe. Today, the Coral Anthelia’s M 46 DF engine can run on LNG, marine diesel oil and heavy fuel oil—reaching industry-leading efficiency in gas mode. Using LNG eliminates the emission of sulfur and particulate matter and reduces emissions of NOx and CO2 by 90% and 20%, respectively.“LNG as a cargo creates a natural boil-off gas,” says Frans Juhrend, customer support project engineer at Bolier. “Anthony Veder wanted to find a solution to consume this gas and not release it into the environment. They decided to adapt the engine in order to consume the boil-off gas—hence the conversion to run on gas as fuel.”Anthony Veder wanted to install a dual fuel engine at the time of the ship’s construction, but the technology was not quite ready. When it did become available, the company conducted an R&D project to compare in-hull and outside-the-hull retrofits, with the in-hull process emerging as the clear winner.Converting the Coral Anthelia’s MaKTM ...

 Teekay announched that  ''Creole Spirit'' has sailed out from the Daewoo Shipbuilding & Marine Engineering (DSME)shipyard for sea trials. What started just as a concept has now become reality. Shortly after keel laying in March, installation of the M-type, Electronically Controlled, Gas Injection (MEGI) twin engines was successfully completed.Creole Spirit is Teekay’s first of nine LNG newbuildings equipped with dual fuel two stroke MEGI engines from MAN Diesel & Turbo.The vessel is expected to enter service in January 2016 on a contract charter with Cheniere.Upon delivery, Creole Spirit will be the most efficient LNG ship on the water with the lowest unit freight cost in the world fleet.Source & Image Credit: TeekayIn the starting, I was explicit with you propecia before and after has changed my life. It has become much more fun, and now I have to run. Just as it is improbable to sit.

The three major South Korean shipyards are supporting the use of this engine for auxiliary applications in the LNG Carrier segment where dual-fuel engines are favoured. South Korea currently has more than 80% of the total order book for LNG tankers, while the Wärtsilä 34DF engine has achieved an auxiliary application market share of approximately 70% in this sector.During the first half of this year Wärtsilä has been awarded contracts for 56 Wärtsilä 34DF dual-fuel auxiliary engines for 14 new LNG Carriers being built for four different owners. This means that Wärtsilä has already received orders for nearly 100 such engines from these three yards since it was re-launched with a higher MCR (maximum continuous rating) in 2013. All these orders were placed by South Korea’s three leading shipyards and the ships are being built for European, American, and Asian owners.“The Wärtsilä 34DF dual-fuel engine is a powerful, versatile, and efficient engine that is helping shipping move into the gas age. The impressive track record of 100 engines sold in a two year period speaks for itself. While the success has been universal, with contracts from yards and owners globally, the fact that the world’s largest shipbuilding nation, South Korea, ...

  A new generation “Antigoon” class dredger, called “Scheldt River”, being built by Royal IHC (IHC) in the Netherlands on behalf of the Belgium based DEME Group, is to be powered by Wärtsilä dual-fuel (DF) engines. This will be the first ever dredger to operate on engines capable of utilising either liquefied natural gas (LNG) or conventional marine fuels. The contract with Wärtsilä was signed in July. The 104 metre long vessel will have a hopper volume capacity of approximately 8,000 cubic metres. The scope of supply includes one 12-cylinder and one 9-cylinder Wärtsilä 34DF engines, two Wärtsilä controllable pitch propellers and two transverse thrusters as well as the company’s patented LNGPac gas supply and storage system. “Wärtsilä’s unmatched experience and extensive reference list in dual-fuel engine applications, plus our complete solutions portfolio, were key considerations in the award of this contract. We congratulate the shipyard and owners for taking the decision to have this new dredger become the first to be capable of using LNG or diesel fuel,” says Lars Anderson, Vice President, Engine Sales, Wärtsilä Marine Solutions. “Environmental considerations are extremely important for every new vessel built today. Operating on LNG allows DEME to set new standards in ...

  Caterpillar Marine is currently underway on another dual fuel engine retrofit conversion onboard the 472 foot Fure West tanker, owned by Furetank Rederi. The diesel engine onboard the tanker will be retrofitted in hull to the 7 cylinder M 46 dual fuel platform, with each cylinder offering 900 kW of rated power. Additionally, Caterpillar is also supplying the complete gas system for the tanker, including bunker stations, 2x LNG tanks measuring 4.15 meters by 24 meters and the vaporizer. This project, backed by the European Union and developed with the Zero Vision Tool, will mark the second MaK engine dual fuel retrofit. In 2014, Caterpillar successfully completed the dual fuel engine retrofit conversion on the Anthony Veder Coral Anthelia LNG carrier. “We’re pleased to continue to build upon our successful track record of dual fual conversions in the commercial marine industry and offer an increased scope of supply to our customers,” Finn Vogler, Caterpillar Marine senior engineer noted. “We have a market-ready technology available that our commercial marine customers can be completely confident in and after our success onboard the Coral Anthelia, we have seen the demand for MaK dual fuel solutions increase substantially.” With a bore of 460 millimeters ...

  Mitsui O.S.K. Lines (MOL) has ordered methanol carriers with the world's first methanol burned dual-fueled low-speed diesel main engine. This engine building has already been completed, and its manufacturer, Mitsui Engineering & Shipbuilding (MES), has test-operated the unit using methanol fuel in Tamano Works, and confirmed that it met expected performance. MOL ordered methanol carriers, which will be equipped with this diesel main engine, from Minaminippon Shipbuilding. The vessels will be delivered in 2016, and serve for Waterfront Shipping Company under a long-term charter contract. By burning methanol with this diesel main engine, emissions of CO2 and NOx are significantly less when burning methanol rather than fuel oil. Thus, methanol is an important fuel that does not include SOx and can replace fuel oil and thereby place fewer burdens on the environment. Besides using methanol to drive the main engine, the new vessel will be one of the first to install the ballast water treatment system and energy saving devices fitted in front and behind the propellers to help improve fuel efficiency. In other words, this new vessel will offer very eco-friendly performance. MOL will expand its methanol transport service by meeting a broad range of customer needs with use ...

  The first Wärtsilä low-speed two-stroke dual-fuel (DF) engine destined for a commercial application has successfully 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. It will power a new “handy-size” LNG carrier, designed by MARIC, in the fleet of Chinese ship-owner and operator Zhejiang Huaxiang Shipping CO., Ltd. The new vessel is under construction at the shipyard of Qidong Fengshun Ship Heavy Industry CO., LTD, also in the People’s Republic of China.
