    Overview

    The KRISO-WETS (Korea Research Institute of Ships & Ocean Engineering - Wave Energy Test Site) located in the western water side of Jeju Island, was officially opened in the last September 2020. There are five berths including the existing Yongsoo OWC-type WEC, which is working as the first berth for the OWC-type WECs and also as the offshore substation for the open-sea test site. KRISO led this construction project, and the total budget is about 17.3 million USD. Four more berths, two in shallow water (about 20 meters) and two in deep water (about 40-60 meters), are connected to the offshore substation and grid system, with a total capacity of 5 MW. The fifth berth, 60 meters deep, is expected to be used for floating offshore wind turbines as well.
