For centuries shipping depended on wind, but the industrial revolution changed that. No longer vessels were stuck in the doldrums. Today, with the Paris Climate Agreement in mind, shipping companies are looking at wind again for efficiency reasons. Recently C-Job Naval Architects has delivered the design for a wind-assisted general cargo vessel to Dutch shipping company Switijnk Shipping. The 8,500 DWT vessel will be equipped with two Norsepower Rotor Sails that will supplement the main engines and is expected to achieve fuel savings of approximately 14 per cent.
