OYO Corporation Selected as Implementer for JOGMEC's Offshore Wind Power Seabed Geological Survey Project in Iwanai-Minamishiribeshi Offshore (Floating) and Shimamaki Offshore (Floating), Hokkaido, Aimed at Promoting Offshore Wind Power Introduction

OYO Corporation (Head office: Chiyoda-ku, Tokyo; President: Hirofumi Amano; hereinafter referred to as "the Company") is pleased to announce that it has been selected as the prospective implementer for the "Basic Survey for Promoting the Introduction of Offshore Wind Power Generation (Hokkaido Iwanai-Minamishiribeshi Offshore (Floating) and Hokkaido Shimamaki Offshore (Floating): Seabed Geological Survey) Phase 2" project, publicly solicited by the Japan Organization for Metals and Energy Security (JOGMEC).

Background

JOGMEC is promoting the introduction of offshore wind power generation using the Central Method* for sea areas where offshore wind power generation projects are deemed feasible. Specifically, it is necessary to conduct various site surveys to acquire seabed geological survey data required for the basic design of offshore wind power generation facilities, and JOGMEC publicly solicited contractors for this survey.

*Central Method: A mechanism in which the government takes the lead from the initial stages of project formation to conduct surveys and other activities more quickly and efficiently.

Survey Outline

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

Project Title	Basic Survey for Promoting the Introduction of Offshore Wind Power Generation (Hokkaido Iwanai-Minamishiribeshi Offshore (Floating) and Hokkaido Shimamaki Offshore (Floating): Seabed Geological Survey) Phase 2
Project Period	(End) March 20, Reiwa 9 (2027)
Budget Scale	4.1 billion yen

This survey will involve geophysical exploration in addition to boring surveys to obtain seabed geological data necessary for the basic design of floating offshore wind power generation facilities (e.g., wind turbine layout, spacing).

The government aims to form offshore wind power projects totaling 30 million KW to 45 million KW by 2040, as offshore wind power generation is expected to have great potential. To achieve this, not only seabed geological surveys for bottom-fixed types but also efforts for seabed geological surveys for the mass introduction of floating offshore wind power generation are becoming increasingly important.

The Company aims to acquire the largest market share by developing new technologies such as 3D acoustic surveys using underwater speakers, large-diameter PS logging, and deep-water microtremor array surveys and deep-water surface wave surveys useful for seabed geological surveys in floating areas.

Future Developments

The Company will continue to position offshore wind power seabed geological surveys as one of the important growth opportunities for the OYO Group, further promoting capital investment and technological development, and contributing to the realization of a sustainable society.
