HD Hyundai has developed Korea’s first wing sail, a large wind-powered device designed to help ships move more efficiently and reduce harmful emissions. The company successfully tested its prototype on land on June 16 in Changwon, Gyeongsangnam-do.
This wing sail, named “Hi-WING,” was developed by HD Korea Shipbuilding & Offshore Engineering (HD KSOE), an intermediate holding company under HD Hyundai’s shipbuilding division. The company announced the successful land demonstration on June 17.
According to HD KSOE, the demonstration confirmed the sail’s performance and safety. In the second half of 2025, the wing sail will be installed on an MR-class tanker currently operated by HMM to test how it performs at sea.
The wing sail uses the lift force generated by wind, similar to how an airplane wing works, to assist in moving the ship forward. These systems are gaining global attention as wind-assisted propulsion can lower greenhouse gas emissions from ships.
