Jiangnan Shipyard launched its self-designed “Jiangnan Smart Sail”, a wind-assisted propulsion system, according to the China Association of the National Shipbuilding Industry on Monday (15 August).
The design is based on sails used on sand-proof flat-bottomed wooden boats (sand boats) first used in the area of Chongming, Shanghai. These boats used multiple masts and multiple sails and used ropes to change direction of the wind-receiving surface of the sails.
This type of sail has a disadvantage that it can only accept tailwinds but it cannot run against headwinds, according to the shipyard.
“Jiangnan Smart Sail” is based on a high-performance computing platform to evaluate sail aerodynamic characteristics and select airfoil parameters. Depending on the direction of the wind, the sails will produce the best boosting effect with the best position of the sails being selected, saving up to 4% of energy of the ships.
In rough sea conditions, the sails can be quickly retracted and stored to ensure the safety of the ship. The sail surface material of the sail is made of polymer composite materials, and the lightweight design of the whole sail is carried out under the requirement of ensuring structural strength under wind pressure.
The installation of “Jiangnan Smart Sail” is convenient as it does not need to be installed in a dock and can be installed anytime and anywhere according to the needs of the shipowner.
Jiangnan Shipyard is looking to form a modular design of the sail system to suit different sizes and types of vessels.
