Harvest-Frost

Mitsubishi Heavy Industries has announced the delivery of the first of three post-panamax bulk carriers to achieve energy efficient operations through the use of an air bubble lubrication system. The recently delivered bulk carrier, MV Harvest Frost, is the first vessel of its size to use MHI’s proprietary Mitsubishi Air Lubrication System (MALS), which reduces the drag between the vessel hull and seawater by blowing air bubbles produced at the vessel bottom. MHI says that use of the system has been proven to help Harvest Frost achieve a 27% reduction in CO2 emissions compared to conventional bulk carriers, exceeding the target figure of 25%. Harvest Frost was delivered to the U.S. company ADM Harvest Shipping, part of the Archer Daniels Midland Company, following its completion at MHI licensing partner Oshima Shipbuilding Co., Ltd.’s shipyard in Nagasaki, Japan. The vessel was constructed with MHI providing the conceptual design and various green technologies, including the MALS. The new vessel also features a new bow shape designed to reduce resistance, while shallow draught facilities help the MALS achieve its target energy savings. For propulsion, an innovative system is adopted that effectively converts the main engine power into propulsion power by positioning fins forward of the propellers and placing special grooves in the propeller boss cap, according to MHI.
