LNG-Fuelled Bulk Carrier Concept Vessel Reaches 1st Milestone

The Open Hatch Bulk Carrier concept utilising 4 stroke dual-fuel LNG engines.

Oshima Shipbuilding Co., Ltd. and DNV have completed the first milestone of a joint programme to develop the ECO-Ship 2020, a concept design for an open hatch bulk carrier (OHBC) developed to significantly lower fuel costs, meet or exceed regulatory standards and improve commercial performance. The LNG-fuelled open hatch bulk carrier concept features lean-burn four stroke medium speed natural gas engines and has been specifically designed to be fully compliant with future IMO, ECA and Tier III emmission requirements, emitting about 50% less CO2 than typical existing OHBCs. A significant part of the reduction is due to the highly efficient propulsion system running on LNG.

Oshima’s president Hiroshi Minami says that the company is committed to helping customers improve environmental and commercial performance. “Our objective is to be the first shipyard to deliver an LNG-powered bulk carrier,” he says. “To achieve our goal, we worked closely with DNV and other suppliers to develop a viable design concept. We are confident the results will exceed expectations.”

According to Adam Larsson, project manager for DNV, the project involved valuable input from Rolls-Royce Marine on LNG, machinery and propulsion solutions, while Kockums and FiReCo helped develop composite GRP solutions. “ECO-Ship is an innovative concept, but every feature is based on existing or emerging technologies,” he says. “And as one of the world’s leading yards for bulk carriers, Oshima’s commitment to more environmental-friendly shipping represents a clear sign that the industry is getting serious about LNG-fuelled shipping.”

Larsson notes that the ECO-Ship’s design is not only innovative but practical –  saving on fuel costs, reducing emissions and staying ahead of new regulations. “Rising demand for more fuel efficient ships combined with new technologies and Oshima’s shipbuilding expertise, will help to turn the ECO-Ship from a concept to a reality,” he says.
