World’s First Wind Sail Fitted VLCC Launched in China


CCS attended the naming ceremony of 307,000-dwt, 333-m VLCC New Aden at Dalian Shipbuilding Industry Co, together with the owner China Merchants Energy Shipping and China Shipbuilding Trading Co, reports Riviera.

Slashing fuel consumption

China Merchants Group chairman Miu Jianmin named the vessel. CCS vice president Fan Qiang represented CCS at the ceremony and said New Aden is “one of the most advanced VLCCs ever built in China”.

New Aden is equipped with two pairs of new-generation rigid wing sails. The rigid wing sails use airflow to change the flow field on the surface of a specific device, thereby generating propulsion using aerodynamic principles.

New Aden’s four sails are made of a carbon fibre composite for the first time, material properties and construction techniques of which need to be verified by practice. CCS proposed optimisation and construction considerations for the new-generation rigid wing sail, working closely with the shipyard and shipowner to ensure high quality and efficient delivery of the shipbuilding project.

CCS believes the sails will slash average fuel consumption by nearly 10% on the Middle East to the Far East route, cutting an estimated 2,900 tonnes of CO2 emissions a year.

Mr Qiang said, New Aden is an outstanding vessel which embraces the very latest design techniques as we work towards meeting the IMO greenhouse gas emissions reduction targets.”

More about the sails

“China Merchants, Dalian Shipbuilding’s R&D team and Guangwei Composite Materials have undertaken great work in developing the ship and this new generation of rigid wing sail. The sails have a combined surface of around 1,200 m3 and are a true innovation.”

Mr Qiang explained the construction of the rigid wing sails, “They are made of a low-weight carbon fibre composite supported by high-strength corrosion resistance and a state-of-the-art autonomous control system. This system maximises efficiency in complex operating conditions. The technology monitors power supply and self-inspects to ensure the hydraulic lifting and electric rotation is optimised to ensure peak performance.”

Mr Qiang added that New Aden sets new standards in VLCC performance. “Together with China Merchants and Dailian Shipbuilding we have looked at every aspect of design to deliver the best possible result in fuel reduction, sailing performance in wind and waves through optimised hull design as well as safety and environmental protection,” he said.

New Aden further meets the requirements of Harmonized Common Structural Rules, the latest oxynitride and oxysulphide emissions standards, the update phase requirements of the Energy Efficiency Design Index and the Energy Efficiency Existing Ship Index. It further meets the EU Inventory of Hazardous Materials and ship recycling rules in line with the latest oil major requirements.”
