China Merchants Group has recently signed a contract with China Shipbuilding for two Very Large Crude Carriers (VLCCs) that will sail, powered, in part, by the wind while gliding on a cushion of air bubbles.
The two 300,000 DWT tankers will feature four rigid wing sails to provide wind-assisted propulsion. These ships will not be the first VLCCs with wing sails. In November 2018, China Merchants took delivery of New Vitality, a 300,000 DWT tanker with two rigid wing sails. The sail-assist provided on the New Vitality must have been successful, as the new ships will have double the number of wing sails of their near sister vessel.
