DNV GL reduces the impact of variations in ship construction

Ensuring that the actual ship delivered is as good as its design DNV GL has launched a new service named Build2Design to help shipyards and shipowners improve the fuel economy of their ships by reducing variations in their building process.Significant improvements have been achieved in the design of more fuel-efficient ships in recent years. The performance of these Eco-Ship designs has been documented by both Computational Fluid Dynamics (CFD) and tank testing and some designs have also proven their performance in operation. However, questions have been raised about variations in performance and research has now 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. 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," says Michael Aasland, Business Director for Bulk Carriers at DNV GL.Dr Olav Rognebakke, Head of Hydrodynamics at DNV GL, adds: "Build2Design is based on a solid theoretical foundation combined with the latest technology and uses advanced CFD calculations to identify the parameters that affect fuel consumption and the effect of ...
