Toyo Construction Co., Ltd. announce that we have decided to construct a self-propelled cable-laying vessel as follows at the board meeting held December 8, 2023. Projects of offshore wind power generation are progressing well mainly in the area of bottom-fixed type, and together with technology development of floating type and consideration of EEZ expansion, it is steadily advancing towards the realization of carbon neutrality by 2050 in line with the government target. Will construct one of the largest self-propelled cable-laying vessels for offshore construction works including offshore wind power generation in which the market is expected to grow.

The cable-laying vessel to be constructed is designed to fit the requirements of environmental conditions and construction conditions in Japan, which allows construction at a high utilization rate in a vast marine area, from shallow area to very deep area where floating wind power generation or DC power transmission projects are conducted. Also, the vessel can be used not only as a self-propelled cable-laying vessel, but also, with a high-performance crane and wide deck, can be used for various purposes including bottom-fixed type foundation works, floating offshore wind power mooring works as well as marine resource development. Primary specification: Gross tonnage: approx.

11,500 t, Thrust power: approx. 13,000kw, DPS Class2. Ship's classification: Class NK; Accommodation capacity: 90 persons (all private rooms, fully equipped with shower & restroom); Dimensions of vessel: 150 m long x 28 m wide x 12 m deep max.

draft: 7.0 m. Cable tank: Capacity: 9,000 t (including portable-type). Main/Sub crane: Lifting capacity of 250 t /100 t (with active heave compensation). Other equipment: Helideck, 4-point mooring device (for works in shallow sea area), 2xROV system, Storage battery system.

Investment value Approx. 30 billion yen. Financing: Own funds and bank loan (Green Loan scheduled).

Construction schedule: Contract conclusion: Mid-December 2023 and Completion and delivery: First half of 2026. The impact of this investment on consolidated performance for this term is expected to be slight. This investment has been also reflected in the mid-term business plan released on March 23, 2023, and the impact on consolidated performance is slight.
