DNV has awarded Approval in Principle (AiP) for a rotor sail system developed by Daewoo Shipbuilding & Marine Engineering (DSME). The technology is designed for large oil tankers and LNG carriers.
The virtual AiP ceremony was attended by Hwa-Lyong Lee, DNV Business Development manager, and the head of DSME’s R&D Institute, Dong-Kyu Choi. The approval follows a joint development project and a review of the system against DNV’s recently developed standard for the certification of wind-assisted propulsion systems.
Vidar Dolonen, DNV’s Regional Manager in Korea and Japan, commented: “We are pleased to deliver the AiP, which is a milestone for the development of wind-assisted propulsion systems. DNV has comprehensive expertise in this area, and we look forward to being a partner in enabling the further development of these technologies.”
The Daewoo system is based on the Magnus effect, which uses the forward thrust developed by spinning cylinders, to supplement ship power.
