DNV GL awards AiP for new Oshima composite tween deck design
At Nor-Shipping today, DNV GL and Oshima Shipbuilding launched a new state-of-the-art 65k open-hatch general cargo carrier design. 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. This tween deck solution was also awarded an Approval in Principle (AiP) by DNV GL. The AiP was presented to Sho Minami, the CEO of Oshima Shipbuilding Co., Ltd, by Knut Ørbeck-Nilssen, CEO DNV GL – Maritime.
The new design features a high cubic and deadweight capacity at a shallow draught, enabled by an increased breadth without compromising performance. This allows 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. One of the design’s most prominent features is the use of tween decks to maximizes the vessel concept’s space utilization.
Jointly developed by Oshima, DNV GL, CompOcean and IKNOW Machinery, the tween decks are made of composite material, which also makes them 50 per cent lighter than steel versions, without sacrificing any of the functionality, service or safety. In addition, the design boasts battery assisted crane operations, a propulsion arrangement with a PTO/PTI shaft generator and the possibility to select different fuel and technology options to meet current and future emissions regulations.
