The 15MW floating offshore wind power model developed jointly by Daewoo Engineering & Construction (CEO Jeong-wan Baek) with Monobasewind (MBW), a Dutch offshore wind power company, has received basic conceptual design approval from the Norwegian Register (DNV 1), an international certification body.

It was announced on the 14th that approval (AiP 2) was obtained.

DNV (Det Norske Verias, Norwegian Register): The world's No. 1 international certification body in the offshore wind power sector

AiP (Approval in Principle): Basic approval for the conceptual design of new technology

After signing a business agreement with MBW in November 2021 for the joint development of a floating offshore wind power model, Daewoo E&C completed the hydraulic model test in March 2022 and acquired an international patent in September 2023.

Unlike fixed offshore wind power, floating offshore wind power has the advantage of being able to be transported and installed after manufacturing the superstructure on land, and because the load acting on the system is small, existing fixed offshore wind power generators can be used as is. In particular, the newly developed elevating spar-type floating body MSPAR 3) was designed to ensure the stability of the floating body even under extreme environmental conditions in the East Sea such as typhoons (maximum wind speed 61 m/s, maximum wave height 11.5 m).

MSPAR: Movable SPAR (Single Point Anchor Reservoir)

MSPAR improved economy and efficiency by using a hybrid material that mixes concrete and steel. MSPAR takes different forms at each stage. During the assembly and transportation stages, it is a semi-submersible type with raised ballast 4) 5) and during the installation and operation stage, it is a stable spar with lowered ballast. 6) It takes shape and produces electricity.

Ballast: A device that maintains the balance of a floating body, such as ballast water on a ship.

Semi-submersible: Applicable to water depths of 50m or more, and has a low draft, making it advantageous for assembly/transportation on quay walls.

Spar: Applicable to water depths of 120m or more, a structure that ensures stability by lowering the center of gravity

An official from Daewoo Engineering & Construction said, 'With the AiP approval of Korea's largest 15MW floating offshore wind power model developed by our company, we have secured bid qualification for the Ulsan floating wind power project,' adding, 'Technology development in the field of new and renewable energy, which is becoming increasingly important. 'We will actively participate in projects.'
