DNV GL has launched a new service called Build2Design to help shipyards and shipowners improve the fuel economy of their ships by reducing variations in the shipbuilding process.

The classification society has developed the service because although significant improvements have been achieved in the design of more fuel-efficient ships in recent years, performance and research has shown a wide variation in different ships of the same design.

“We have compiled data that shows there is a large variation in fuel consumption between ships of the same design. Build2Design aims to ensure that the actual ship delivered is as good as its design,” said Michael Aasland, business director for bulk carriers at DNV GL - Maritime.

He said that Build2Design is based on a solid theoretical foundation combined with the latest technology and uses advanced CFD calculations to identify the different parameters that affect fuel consumption. When developing the new service, DNV GL undertook a sensitivity analysis of over twenty parameters and considered the fuel impact of each.

From the first pilot project carried out on the Green Dolphin 38 design, a conservative estimate has shown that a saving of 2% can be achieved, which equates to 80 tonnes of fuel and a saving of US$50,000 per year.

DNV GL said that corresponding figures for a typical Capesize bulk carrier are 200 tonnes of fuel and a subsequent saving of US$120,000 per year.

The new service is being rolled out this spring, both through the Green Dolphin 38 pilot project for Goldenport at CSI Jiangsu and the first commercial project based on a Seahorse 35 design for Graig Shipping at Jiangdong SY.
