At Nor-Shipping Confernece, DNV GL and Oshima Shipbuilding launched a new 65k open-hatch general cargo carrier design, 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 solution was also awarded an Approval in Principle (AiP) by DNV GL.
As Sho Minami, CEO of Oshima Shipbuilding Co., explains, several new technologies for general cargo carriers have been implemented, such as composite tween decks, a PTO/PTI shaft generator and batteries, resulting in a design that offers shorter port handling times, reduced maintenance costs and cost-effective manufacturing process.
“The cooperation with DNV GL on developing the overall design and the tween deck solution was very successful and we are very proud to receive the AiP, after seeing the first full-size prototype of the tween decks through testing,” he adds.
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 more feature is the use of tween decks to maximize 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.
“This innovative, open-hatch general cargo carrier design is a good example of how cooperation between industry partners can benefit the maritime industry” says Knut Ørbeck-Nilssen, CEO DNV GL – Maritime. “The jointly developed tween deck demonstrates how composite materials can save weight and bring additional benefits, without compromising on safety” he adds.
