A new AHTS vessel design has been launched by Wärtsilä at this year’s Sea Asia exhibition. The focus of the new design is on simplicity, efficiency, low fuel consumption and a reduced environmental impact.
The equipment solutions are suitable for a medium to large size AHTS vessel, where one of the key components is a 2-speed gearbox system selected to meet the design targets of reduced costs and less complexity without compromising operational safety. Wärtsilä estimates that the new design provides a reduction of 20 to 25 percent in fuel consumption compared to conventional diesel mechanical four engine solutions. The exhaust emissions are reduced accordingly.
