  By 2016, 24 of the largest ships in Hapag-Lloyd’s fleet will get a new bulbous bow, and some will also be fitted with optimised propellers. This will enable the vessels to consume less fuel and produce fewer emissions. It’s as high as a truck, weighs about 250 tonnes and is a prominent feature at the very tip of the bow of modern container ships. This has little to do with aesthetics and much more to do with fuel efficiency. The bulbous bow – the nose of the ship – displaces water in a manner that mini-mizes or even completely eliminates a bow wave. The lower the water resistance on the hull, the less fuel a ship needs in order to travel at the same speed. If a ship’s fuel consumption decreases, its emissions also drop. “For this reason, we continuously analyse how to make our ships even more efficient,” explains Richard von Berlepsch, Managing Director Ship Management. As a result, this distinctive part of the vessel is now being retrofitted in four of Hapag-Lloyd’s biggest ship classes. One by one, the 13,200 TEU ships in the “Hamburg Express” class and the 8,750 TEU vessels in the “Colombo Express,” “Prague ...

  Researchers from the Norwegian University of Science and Technology (NTNU) are testing a model "whale's tail" that can be attached to ships to improve fuel efficiency. NTNU is conducting these tests in the Marintek Towing Tank in cooperation with Rolls-Royce and the British companies Seaspeed and MOST. A 1:16.57 scale model ship is attached to the back of the platform that sails the man-made waves of the Towing Tank. It only takes a few seconds to cross the 200-metre-long tank, but valuable information is still being collected. Cameras and advanced measuring equipment show how the model moves, the resistance against it, and how changes affect it. The person responsible for testing this invention is Eirik Bøckmann, a postdoctoral fellow at the Department of Marine Technology at NTNU. He has been working on this idea for several years. Using wave energy The main goal of the whale's tail is to help reduce fuel use by using wave energy to help the ship move forward. A whale's tail may not be the first thing that you think of when you see this invention— it looks like two wings, or fins that are attached to the front of the ship. But the ...

  Wärtsilä is launching a series of four new container feeder vessel designs at this year’s Nor-Shipping exhibition being held in Oslo from June 2 to 5. The innovative designs are based upon achieving optimal fuel efficiency, while being compliant with all known current and future environmental regulations.  The four ship designs, namely the WSD80-1500, WSD80-2400, WSD80-4000 and WSD84-2400, feature exceptionally low and best-in-class fuel consumption. Each design is available in three versions; ‘conventional’ using HFO as fuel, ‘environmental’ using HFO with exhaust cleaning scrubber systems, and ‘clean’ with dual-fuel capability and running mainly on liquefied natural gas (LNG). Wärtsilä’s technology and experience in the development of dual-fuel marine engines and LNG fuel supply systems is a key enabler of ship designs that efficiently anticipate the global adoption of LNG as a marine fuel. Fuel flexibility is, therefore, a main feature of these latest Wärtsilä designs along with fuel efficiency, cargo capacity, systems redundancy and the lowest possible levels of exhaust emissions. Since container feeder vessels operate largely within existing or anticipated ECA (Emissions Control Areas) or SECA (Sulphur Emissions Control Areas), environmentally compliant designs are extremely relevant. “Wärtsilä is a global supplier of efficient, reliable, and environmentally sustainable ship ...
