Penta-Ocean Construction (President Takuzo Shimizu, hereinafter POC) hereby announces that on December 3, 2024, the company has signed a shipbuilding contract with PaxOcean Group (CEO Tan Thai Yong) on the construction of a self-propelled large-scale cable laying vessel (hereinafter CLV), utilized for offshore wind construction.
The offshore wind power generation in Japan is currently progressing with a focus on the development of bottom-fixed offshore wind power facilities in the port areas. After FY 3/28, we expect the start of full-scale construction in the general sea areas.
As a leading company in marine civil engineering, we have been actively investing in the construction of large-scale work vessels required for offshore wind construction including offshore installation vessels, in an effort to contribute to the expansion of offshore wind power supply in Japan.
In order to expand our business from offshore wind turbine construction to power cable laying, we have decided to build the world’s largest and most advanced CLV, eyeing future offshore wind power construction in the EEZ as well as in the general sea areas.
The CLV is capable of laying and burying not only cables for bottom-fixed offshore wind turbines but also for floating-type offshore wind turbines, as well as submarine direct current power transmission cables.
The new CLV is large and self-propelled, mounted with two 5,000t cable carousels (a total of 10,000t) also known as cable storage, enabling safe and efficient cable laying in the open sea with severe metocean conditions. Equipped with a latest trencher (for burying cables) and work class ROV, the vessel can efficiently perform cable burial work.
The ship design will be contracted to Salt Ship Design (Norway), known for its extensive experience in CLV design, while the shipbuilding will be assigned to PaxOcean (Singapore), the shipbuilder of our offshore installation vessel "CP-16001." Furthermore, the trencher and work class ROV will be equipped with latest equipment from SMD (UK), renowned for its extensive track record of reliability.
Once completed, the main CLV will be jointly owned by our subsidiary (to be established, 50% share) and Fuyo General Lease Co., Ltd. (President, CEO and Representative Director Hiroaki Oda, 50% share). The trencher (a burying machine) and work class ROV for the CLV will be jointly owned by our subsidiary (to be stablished, 65% share) and Kojimagumi Co., Ltd. (President Tokuaki Kojima, 35% share). We will entrust Kojimagumi with the operational management of the vessel.
The construction cost of CLV is approximately JPY 31 bn for the hull, and approximately JPY 5.5 bn for the trencher and work class ROV, a total of approximately JPY 36.5 bn. The vessel is scheduled to be completed in February 2028 and begin operations in the first half of FY 3/29.
We are confident that the CLV will make a significant contribution to further spread and promotion of Japan’s offshore wind power through realization of "safe and efficient construction" and "reasonable construction cost".
