DNV GL Service Promises Newbuild Fuel-Efficiency Guarantee
A new service from class society DNV GL promises to ensure that newbuild ships live up to the fuel-efficiency promised by their designers.
"We have compiled data that shows there is a large variation in fuel consumption between ships of the same design," said Michael Aasland, business director for Bulk Carriers at DNV GL - Maritime.
"This has led us to develop a new service, Build2Design, which aims at ensuring that the actual ship delivered is as good as its design."
The service uses computational fluid dynamics (CFD) to identify factors in fuel consumption such as the positioning and alignment of the bilge keel.
"Advanced CFD calculations show that a 0.5% reduction in resistance can be achieved by adjusting the position and angle," Aasland said.
Results of an initial pilot project suggest the service could achieve a savings of 2 percent in efficiency, which would amount to 200 tonnes of fuel, or $120,000, per year for a typical Capesize bulk carrier.
"Today, hull lines are optimised with much greater sophistication than only a few years ago," Aasland said.
"DNV GL's Build2Design service ensures that both yards and shipowners benefit from the latest research and best practices."
Fellow class society ClassNK recently announced that it would buy software firm Napa in an effort to offer more support for efficient design innovations.
