Ekwil is a joint venture specializing in FOWT, formed with SBM Offshore (headquartered in the Netherlands), the world's largest developer and operator of FPSO (Floating Production, Storage and Offloading), and Technip Energies (headquartered in France), has delivered a high number of floating facilities related to oil and gas, including the world's first Floating LNG. Ekwil is benefiting from the execution EPCI of a FOWT pilot farm of 3 floaters (25MW) in France and is participating as a contractor in the construction project of the world's first commercial FOWT planned off the coast of Ulsan, South Korea, making it a top runner in the industry as a technology provider and contractor for

floating design in offshore wind power projects worldwide, particularly in Europe and the Asia-Pacific region.

Chiyoda and Technip Energies had signed a non-exclusive*2 MOU for FOWT projects in Japan*3. Following the establishment of Ekwil as a joint venture between SBM Offshore and Technip Energies on July 6, 2024, discussions have led to the signing of this MOU. It grants Chiyoda and Ekwil the opportunity to collaborate first on floating structures based on Ekwil's technologies.

Chiyoda have a wealth of experience in EPC for renewable energy-related facilities and petrochemical/LNG receiving terminals in Japan. Chiyoda have been accumulated knowledge by bottom-fixed offshore wind turbine project in Japan since 2018 and have successfully completed multiple basic design projects. In the FOWT projects, Chiyoda have also received and are working on several feasibility studies. We are confident that by combining the technologies and know-how of both Chiyoda and Ekwil, we can develop cost-competitive and highly feasible construction plans for FOWT projects in Japan.

Chiyoda will accumulate knowledge in this field through practical experience in the construction, procurement, transportation, and installation of wind turbines, as well as project management. Through the safe and feasible implementation of FOWT, we aim to embody our purpose of 'Enriching Society through Engineering Value' and actively work towards achieving a carbon-neutral society.
