It's and energy efficient open-hatch bulk carrier

Developed as low fuel consumption eco-friendly ship Mitsui Engineering & Shipbuilding Co., Ltd. (with president Mr. Yasuhiko Katoh) has agreed with a first class shipowner to build 2 units of "neo Supramax 66BC", 66,000 dwt bulk carriers of next generation newly developed as low fuel consumption eco-friendly ship.Keeping the superior usability of MES best selling 56,000 dwt type handymax bulk carrier which achieved over 170 contracts, this new and larger type bulk carrier is expected to establish a new segment in bulk carrier market. Development of the ship's design was preceded by hearings from various owners and operators and investigations on more than 600 ports all over the world. This ship is designed to have over-Panamax beam (36m) and shallow draft in consideration of prevailing trade patterns and the expansion of Panama Canal in 2014.Despite its larger deadweight and cargo capacity than Mitsui 56, neo Supramax 66BC achieves even less fuel consumption by adopting newly developed hull form and other energy saving equipment.At IMO MEPC62 held from 11th to 15th July, 2011 in London, implementation of new energy efficiency design index (EEDI) and actual restrictions on fuel consumption in line therewith have been adopted.

Nano structured surfaces that make organisms fall off when the ships move Organisms, such as , sticking to the lower structure of ships are increasing the required propulsive power. It is estimated that ships' fuel consumption could be reduced by up to forty percent by removing those organisms. Erosive systems containing biocides are mainly used for this purpose.However, the use of eco-friendly alternatives such as silicon based fouling release coatings, nearly all enhanced with an oil additive, have increased lately. Researchers at GE Global Research Center in the U.S. have shown that organisms react differently to the various silicone fouling release coatings, and coating type crossed with oil type is very important when it comes to establishing an organism's attachment strength magnitude.However, there is a need for improved eco-friendly alternatives and researchers are working on solutions. For example, scientists at the University of Gothenburg in Sweden have developed what they call a "low emission" approach where avermectins, a class of antibiotics, are included. Only very small amounts are released, since the substances in the coating are tightly associated with the binding matrix agent.The scientists found that 1mg avermectin/gr coating very effectively hindered adult barnacles from colonization, but a similar coating ...
