emissions by about 21% on a tonne-mile emissions will
be achieved by applying optional software and hardware to vessel operations taking the overall savings to 30%.

Bulk Carriers Mitsui launches
green bulker Mitsui Engineering & Shipbuilding Co., Ltd. (MES) has developed a new green generation of bulk carriers with the launch of the 66,000dwt ship which it calls the ‘neo Supramax 66BC’. MES said the new design will reduce CO2
emissions by
30%. Although the 66BC is effectively an enlarged
version of the 56,000dwt handymax bulk carrier, the new vessel has seen some major develop- ment work with a wide beam (36m) and a shallow draft which is taking into consideration the trade patterns of the 56BCs and the expansion of the Panama Canal, which is expected by 2014. The neo Supramax 66BC newly developed
energy-saving hull form and is larger than 56BC, but even so the new ship is far more fuel efficient than its earlier cousin. MES said that it has two types of specification of the 66BC, a premium and a standard model.
10 The Naval Architect January 2011
of the Portsmouth based subsidiary of Houlder Limited, explains that the Aura incorporates vertically positioned LNG- bunker tanks with one duct leading directly from the engine room to the atmosphere. In the bulk of the LNG cargo-fuel-system designs produced to date, the cargo tanks are positioned horizontally often under accommodation or passenger areas. This has flagged up concerns as it goes against existing practice and is not allowed within the International Gas Code (IGC), which governs the construction and equipment of ships carrying liquefied gases. Mr Alderson, who has considerable LNG experi-
ence and has been involved in the development of the new International Gas Fuelled (IGF) Code for the past three years, confirms a patent has been applied for and explains the company is in talks with a Classification Society and several shipyards about the design, adding talks are “fairly advanced with one of them”. He goes on: “We have also incorporated the arrangement into other Hart, Fenton & Company designs – predominantly offshore support vessels, ro-ros and ferries as we think this is where the demand will start.” The company is also investigat- ing bunker and storage solutions.
