MOL orders methanol- fueled carriers

  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 ...

Anthony Veder to introduce Innovation in short-sea LNG shipping

  Anthony Veder’s 6,500 cbm LPG/LEG/LNG carrier Coral Anthelia has been retrofitted with a dual-fuel (DF) engine that enables it to run on boil-off gas when transporting LNG. Having successfully completed its sea trials, the vessel operates in the North Sea and Baltic Sea and regularly loads LNG at the Rotterdam Gate Terminal. “This great result was achieved by committed partners working effectively together in a trusting and safe way. Not only was this project completed ahead of time and within budget, it was also executed without any safety incidents. This breakthrough innovation in the use of LNG for short sea shipping shows that retrofitting a tanker to run on LNG is both technically and financially viable”, says Anthony Veder CEO Jan Valkier. The vessel was delivered to Anthony Veder in 2013 with a conventional six-cylinder MaK M43C diesel engine. With the vessel’s design already optimised for ethylene trading, a new target was set: consumption of the boil-off gas as fuel when carrying LNG and without completely replacing the one-and-a-half year old engine. The solution was found by retrofitting the engine to make it a MaK M46 dual-fuel engine. This was achieved making use of a dedicated package that recently ...
