Japanese shipbuilder Mitsubishi Heavy Industries (MHI) has secured a contract from Ocean Breeze LNG Transport (OBLT), a joint venture (JV) between Kawasaki Kisen Kaisha (K Line) and a subsidiary of Inpex, to build a ‘Sayaendo‘ series new-generation liquefied natural gas (LNG) carrier.
Construction of the new 75,000dwt LNG carrier will be carried out at the company’s Nagasaki Shipyard & Machinery Works.
The new vessel will have a length of 288m, a width of 48.94m, draft of 11.55m, and will be capable of carrying up to 155,000m³ of LNG using four Moss-type hemispherical tanks at a service speed of 19.5 knots.
In MHI’s Sayaendo series LNG carriers, the upper half of the tank is covered by a hemispherical dome, while the lower half under the deck is supported by a cylindrical skirt structure that is intended to reduce fuel consumption and offer improved maintainability.
The hemispherical cover will help in reducing size and weight while maintaining overall hull rigidity of the vessel.
MHI said the cover over the tanks is expected to enhance aerodynamics by reducing wind pressure, which acts as a drag on ship propulsion.
Compared to conventional ships, Sayaendo series vessels will consume 20% less fuel due to the reduction in size and weight, along with improvements to the hull line.
The new vessel is scheduled to be delivered to OBLT at the end of 2016, following which it will be used to transport LNG procured by Inpex from the Ichthys project off the coast of Western Australia.
MHI and Imabari Shipbuilding set up a new joint venture (JV) company called ‘MI LNG Company’ in April 2013 to manage the design and marketing of LNG carriers.
MHI also signed an agreement with Mitsui OSK Lines (MOL) in May 2013 for the construction of a ‘Sayaendo’ series new-generation LNG carrier, which will be used to transport LNG produced by the Ichthys project for Osaka and Kyushu from 2020.
