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 ...

Qatar Champions LNG as Cleaner Marine Fuel

Qatari shipping company Nakilat and Qatari LNG producers Qatargas and RasGas Company Limited have agreed with engine manufacturer MAN Diesel and Turbo to convert a Q-Max vessel to use LNG as an alternative to heavy fuel oil in the main engines. The proactive initiative reinforces Qatar's commitment toward the environment with plans to convert an existing low-speed diesel LNG carrier to use LNG as fuel thereby reducing the ship's exhaust gas emissions. Shipyard operator Nakilat-Keppel Offshore & Marine (N-KOM) will complete the ship's conversion at its Erhama Bin Jaber Al Jalahma Shipyard facilities in Qatar's Port of Ras Laffan. The modification will utilize MAN Diesel and Turbo's ME-GI (M-Type Electronically Controlled - Gas Injection) systems as an innovative and flexible technology. The Q-Max will be the world's first low-speed marine diesel engine to be converted to use LNG as a fuel. The modification will meet current known and future stated global emissions regulations. The control of greenhouse gas and exhaust gas emissions have a high priority in today's shipping industry. In-step with the emissions regulations, the engine manufacturer, MAN Diesel and Turbo has made technical advancements to the low speed diesel engine to have flexibility to utilize Liquefied Natural Gas ...
