New Bulker Design Reduces Wind Resistance to Lower Bunker Costs
Japan's Tsuneishi Shipbuilding Co., Ltd. (Tsuneishi) says it is introducing a new type of bulk carrier with fuel-saving features including a new method of cutting wind resistance.
The TESS64 AEROLINE is a 63,700 deadweight tonne (dwt) vessel, a step up in size from the company's TESS58 bulkers, which were previously the largest in its Tsuneishi Economical Standard Ship (TESS) handymax series.
The new design features the company's AEROLINE technology, which uses cut-corner design and a new streamlined shape for the fore upper bow, cutting wind resistance by 10 percent.
Other fuel-saving features of the TESS64 include optimised propellers for lower vibration and more efficient propulsion and an air intake system that improves the engine's fuel efficiency.
Overall, the shipbuilder says the improvements mean a 20 percent increase in fuel efficiency compared with conventional TESS58 models.
The new design also has a shallow draft to meet port restrictions.
In April, Tsuneishi announced its first order for new ships from a state-owned Chinese company, for four fuel-efficient containerships.
