Selected as Contractor for JOGMEC's Public Tender: Seabed Ground Surveys for Floating Offshore Wind Power Promotion in Hokkaido (Iwanai-Kyowa/Minami-Shiribeshi and Shimamaki Areas)

OYO Corporation (Headquarters: Chiyoda-ku, Tokyo; President: Hirofumi Amano; hereinafter "the Company") is pleased to announce that it has been selected as the contractor for the "Basic Survey Work for the Promotion of Offshore Wind Power Generation (Offshore Iwanai-Kyowa/Minami-Shiribeshi and Offshore Shimamaki (Floating): Seabed Ground Survey) Phase 2," following a public tender by the Japan Organization for Metals and Energy Security (JOGMEC).

Background

JOGMEC is working to promote the introduction of offshore wind power generation through the "Centralized System*" in sea areas where offshore wind power projects are deemed feasible. Specifically, various site surveys must be conducted to acquire seabed ground survey data necessary for the basic design of offshore wind power facilities, and JOGMEC issued a public tender for these services.

*Centralized System: A mechanism in which the government takes a leading role from the initial stages of project formation to conduct surveys and other activities more quickly and efficiently.

Survey Overview

The overview of the survey as stated in the public tender documents is as follows:

Subject

Basic Survey Work for the Promotion of Offshore Wind Power Generation (Offshore Iwanai-Kyowa/Minami-Shiribeshi and Offshore Shimamaki (Floating): Seabed Ground Survey) Phase 2

Project Period

(End date) March 20, 2027

Budget Scale

4.1 billion yen

In this survey, in addition to physical exploration, boring surveys will be conducted to obtain seabed ground data necessary for the basic design (wind turbine layout, installation spacing, etc.) of floating offshore wind power facilities.

The government is aiming to form projects totaling 30 to 45 million kW by 2040 for offshore wind power, which is expected to have significant potential. To achieve this, it is becoming increasingly important to engage in seabed ground surveys not only for fixed-bottom types but also for the mass introduction of floating offshore wind power.

The Company aims to capture the largest market share by developing new technologies such as 3D acoustic surveys using underwater speakers and large-diameter PS logging, as well as deep-sea microtremor array exploration and deep-sea surface wave exploration, which are useful for seabed ground surveys in floating offshore wind areas.

Future Outlook

The Company will continue to position seabed ground surveys for offshore wind power as one of the OYO Group's key growth opportunities, and will continue to advance capital investment and technological development to contribute to the realization of a sustainable society.
