ECO-Ship 2020
Oshima Eco-Ship at sea
The ECO-Ship 2020 is an energy-efficient and cost-effective concept design developed to help owners and operators improve commercial performance while lowering fuel costs. The LNG-fuelled open hatch bulk carrier concept features a number of innovative solutions, including a wide twin skeg hull, Oshima’s Seaworthy bow, air lubrication system, lean-burn four stroke medium speed gas engines and a flexible propulsion and power generation system with shaft generator/motor (PTO/PTI).
The concept also features a waste-heat recovery system that can feed electric power into the PTI to be used as a supplement to ship propulsion power, representing about 5% fuel savings at normal cruising speeds, according to DNV. The ECO-Ship is outfitted with four large capacity electric jib cranes and hatch covers made of a composite material that weighs about 50% less than traditional steel covers. The vessel has been specifically designed to be fully compliant with future IMO, ECA and Tier III emission requirements.
