Oshimas Tween Deck Design Gets DNV GL AiP
zoom Classification society DNV GL has awarded an Approval in Principle (AiP) to Oshima Shipbuilding’s new tween deck solution.The parties presented the 65,000 open-hatch general cargo carrier design at Nor-Shipping conference and exhibition in Oslo, Norway.The design concept was developed by both companies in a joint development project. Intended for a wide range of project cargoes and packaged goods, the design includes composite tween decks to maximize space utilization and save weight.The AiP was presented to Sho Minami, the CEO of Oshima Shipbuilding Co., Ltd, by Knut Ørbeck-Nilssen, CEO DNV GL – Maritime.“We believe this new ship design delivers an excellent combination of characteristics to meet the varying requirements of the open-hatch general cargo segment. Several new technologies for general cargo carriers have been implemented, such as composite tween decks, a PTO/PTI shaft generator and batteries,” Sho Minami, CEO of Oshima Shipbuilding Co, said.Minami added that this results in a design that offers shorter port handling times, reduced maintenance costs and a simple, cost-effective manufacturing process.The new design features a high cubic and deadweight capacity at a shallow draught, enabled by an increased breadth without compromising performance, allowing the ship to enter a large number of ports. It has eight box-shaped cargo holds with full-width hatch openings, including two long holds for larger project cargoes.Featuring a length of 210 meters and a breadth of 35 meters, the ship has a cubic capacity of 77,000 m3.
