OYO Corporation Selected as Implementer for Seabed Ground Investigation Work Offshore Asahi City, Chiba Prefecture, for Promoting Offshore Wind Power Generation, Publicly Solicited by JOGMEC

OYO Corporation (Headquarters: Chiyoda-ku, Tokyo; Representative Director and President: Hirofumi Amano; hereinafter "our company") applied for "Phase 1 of the Basic Survey for Promoting the Introduction of Offshore Wind Power Generation (Seabed Ground Investigation Offshore Asahi City, Chiba Prefecture)" publicly solicited by the Japan Organization for Metals and Energy Security (hereinafter, JOGMEC) and has been selected as a prospective implementer.

Background

JOGMEC is promoting the introduction of bottom-fixed offshore wind power generation using the central method* for sea areas where the feasibility of offshore wind power generation projects is expected. Specifically, it is necessary to conduct various site surveys to acquire seabed ground data required for the basic design of offshore wind power generation facilities, and JOGMEC publicly solicited contractors for this survey.

*Central method:

A system in which the government takes the lead from the initial stage of project formation to conduct surveys and other activities more quickly and efficiently.

Outline of the Survey

The outline of the survey in the public solicitation documents is shown below.

Project Name

Basic Survey for Promoting the Introduction of Offshore Wind Power Generation

(Seabed Ground Investigation Offshore Asahi City, Chiba Prefecture) Phase 1

Project Period

(End) October 31, Reiwa 9 (2027)

Budget Scale

4.5 billion yen

In this survey, geophysical exploration and boring investigations will be conducted to obtain seabed ground data necessary for the basic design of bottom-fixed offshore wind power generation facilities (wind turbine arrangement, installation spacing, etc.).

The government aims to form projects for 30 million KW to 45 million KW of offshore wind power generation by 2040, which is expected to have great potential. To achieve this, seabed ground investigations for bottom-fixed structures, as well as efforts for seabed ground investigations for the mass introduction of floating offshore wind power generation, are becoming increasingly important. Our company aims to acquire the largest market share by developing new technologies such as 3D acoustic exploration using underwater speakers and large-diameter PS logging, as well as deep-water seabed microtremor array exploration and deep-water surface wave exploration, which are useful for seabed ground investigations in floating areas.

Future Development

Our company will continue to position offshore wind power generation seabed ground investigation as one of the important growth opportunities for the OYO Corporation Group, and will further promote capital investment and technological development to contribute to the realization of a sustainable society.
