Emerald Ace World?s First Hybrid Car Carrier Mitsui O.S.K. Lines (MOL) announced the completion of the hybrid car carrier Emerald Ace at the Mitsubishi Heavy Industries, Ltd. (MHI) Kobe shipyard, an in- novative ship which is designed to generate zero emissions while berthed. Emerald Ace was built as world?s first newly built hybrid car carrier, and is equipped with a hybrid electric power supply system that combines a 160kW solar generation system ? a system jointly developed by MHI, Energy Company of Panasonic Group, and MOL ? with lithium-ion batteries that can store some 2.2MWh of electricity. Conventional power generation systems use diesel-powered generators to supply on- board electricity while berthed. On the Emerald Ace, electricity is generated by the solar power generation system while the vessel is under way and stored in the lithium- ion batteries. The diesel-powered generator is completely shut down when the ship is in berth, and the batteries provide all the electricity it needs, resulting in zero emis- sions at the pier. The vessel's hybrid system represents a significant step forward in realizing ISHIN-I, the concept for the next-generation car carrier that MOL an- nounced in September 2009. MOL continues to take a proactive stance in technolog- ical development with the aim of reducing the environmental burden of its vessels and operations.MHI Receives Order for LNG Carrier Mitsubishi Heavy Industries, Ltd. (MHI) signed an agreement with Mitsui O.S.K. Lines to build Sayaendo, a series new-generation liquefied natural gas (LNG) carrier. The ship offers improved fuel consumption and maintainability through various fea- tures including enhanced ship structure efficiency. The ship will be used mainly for transportation of LNG for the Kansai Electric Power Co. The LNG carrier measures 288m in length overall, and is 48.94m wide with a 11.5m draft. The 138,000 gt (75,000 dwt) ship is capable of carrying up to 153,000 cu. m. of LNG (cargo tank total volume: 155,000 cu. m.) using four Moss-type tanks. Sayaendo features a peapod- shaped continuous cover for the Moss spherical tanks integrated with the ship's hull, in lieu of a conventional hemispherical cover. This configuration enables greater structural efficiency together with size and weight re- ductions, maintaining the ship's overall strength. The continuous cover over the tanks also improves aerody- namics by substantially reducing wind pressure, whichserves as drag on ship propulsion. For its main power plant, the Sayaendo adopts MHI's "Ultra Steam Tur- bine Plant" (UST), a new turbine plant which achieves higher thermal efficiency through effective use of ther- mal energy by reheating steam. The new unit, in com- bination with downsizing, weight reduction and hull line improvement, enables the Sayaendo to achieve a substantial 25% reduction in fuel consumption compared to conventional ships. In conventional carriers, pipes, wires and catwalks atop the tanks have been supported by complex structures. By covering the tanks with an integrated cover and making those supporting structures unnecessary, the new design improves maintainability. CO2 emissions are also re- duced as a result of lower fuel consumption.
