The company was subcontracted in 2022 by Sumitomo Electric to conduct an initial conceptual design of a self-propelled CLV 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).
The following year, NEDO selected the Japanese shipping player as part of a four-company consortium with Sumitomo Electric Industries, Furukawa Electric, and Mitsui O.S.K. Lines (MOL) for a public solicitation regarding the development of construction methods for the installation of a cable protecting system, and the development of new cable-laying vessels for the same project.
As a result, NYK began designing the self-propelled cable-laying vessel in cooperation with Sumitomo Electric.
In 2024, ClassNK gave its approval in principle (AiP) for the design concept of the cable layer.
With the completion of the basic design and receipt of ClassNK’s GDA, NYK said it had achieved its initial objectives within the NEDO-supported project.
