Bulk Carrier to Ride on Bubbles to Reduce CO2 25%

Mitsubishi Heavy Industries, Ltd. (MHI) has developed a new bulk carrier which it repotes will enable reductions in CO2 emissions by about 25% compared with conventional averaged bulk carriers. As the first commercial application of the new design, MHI will provide its conceptual design and green technologies to three grain carriers to be built for Archer Daniels Midland Company (ADM) of the U.S. MHI's new bulk carrier design adopts the company's proprietary Mitsubishi Air Lubrication System (MALS), which reduces frictional resistance between the vessel hull and seawater using air bubbles produced at the vessel bottom, along with high-efficiency hull form and enhanced propulsion system. Sumitomo Corporation of Japan has received the order for the ship construction from ADM, and Oshima Shipbuilding Co., Ltd. of Nagasaki was selected to build the ships.
Besides the MALS, which uses blowers to create air bubbles under the vessel bottom, the three grain carriers will also feature a newly designed bow shape that will reduce wave-making resistances. For propulsion, the ship adopts a system to effectively convert the main engine power into propulsion power by positioning fins forward of the propellers and placing particular grooves in the propeller boss cap. MHI developed the MALS as a key measure to reduce CO2 emissions from ships. ADM's ships will be the first case in which MHI provides the system to another shipbuilder.
The three grain carriers will be 95,000 dwt vessels: 237m in length, 40m in width, and 12.5m in designed draft. The shallow draft of the ships facilitates the pursuit of energy savings and CO2 emission reduction efficiency by MALS. Oshima Shipbuilding will perform from the basic design work through construction based on the conceptual design and green technologies provided by MHI. Delivery of equipment related to MALS system from MHI is slated for 2014.
The talks to build the three dry bulk carriers began between ADM and MHI. MHI's Shipbuilding & Ocean Development segment has been implementing a policy to promote engineering business, including technological support to other shipbuilders. Under this policy, the company decided to collaborate for this time with Oshima Shipbuilding, a firm that has earned a solid reputation in bulk carrier design and construction through delivery/order receipt of about 60 post-Panamax* class ships. The collaboration has enabled the two companies to provide enhanced cost effectiveness to the customer.
ADM is one of the U.S.'s top-ranking grain companies. The three bulk carriers, which mark the first new shipbuilding order placed by ADM, are designed to accommodate new post-Panamax* needs.
The new bulk carriers are designed to make an important contribution to international efforts to fight global warming, a demand that is especially strong in the case of oceangoing vessels. Going forward MHI will continue to accord priority to the development of vessels addressing CO2 reduction needs by focusing on development of its "Eco-ship" and sales expansion of related systems and equipment.
