Japanese classification society Nippon Kaiji Kyokai (ClassNK) has given its approval in principle (AiP) to Nippon Yusen Kabushiki Kaisha (NYK Line) for a design concept of a cable-laying vessel envisioned to handle the construction of a long-distance subsea direct current (DC) transmission network in Japan.
NYK was subcontracted in 2022 by Sumitomo Electric to conduct an initial conceptual design of a self-propelled cable-laying vessel suitable for Japan’s conditions regarding ‘ Research and Development of a Multi-purpose and Multi-terminal HIGH Voltage Direct Current Transmission System (RIGHT Project) ,’ subsidized by New Energy and Industrial Technology Development Organization (NEDO).
