Nippon Yusen Kabushiki Kaisha (NYK) has received approval in principle (AiP) from ship classification society ClassNK for the design concept of a cable-laying vessel.
The vessel’s design is part of NYK’s collaboration within a four-company consortium, which includes Sumitomo Electric, Furukawa Electric, and Mitsui O.S.K. Lines.
This vessel is integral to constructing a long-distance subsea direct current (DC) transmission network in Japan.
The development is crucial as renewable energy sources like wind power, located in regions such as Hokkaido, need to be connected to high-demand areas, according to the company.
The consortium is engaged in the development of construction methods for the installation of cable protecting system and the development of new cable-laying vessels.
This initiative is part of the larger Research and Development of a Multi-purpose and Multi-terminal HIGH Voltage Direct Current Transmission System (RIGHT Project), which is subsidised by Japan’s New Energy and Industrial Technology Development Organisation (NEDO).
NYK was subcontracted by Sumitomo Electric to conduct the initial conceptual design of the vessel in 2022, as part of the RIGHT Project.
In 2023, NYK was selected by NEDO for a public solicitation to further develop construction methods and new cable-laying vessels under the same project.
With the assistance of Furukawa Electric, NYK has now successfully obtained the AiP from ClassNK for the vessel’s design concept.
NYK will advance to the detailed design phase of the vessel and aim to secure basic design approval from ClassNK.
Last month, NYK and tech provider MTI jointly filed a patent for advanced technology aimed at enhancing the safety of reduced iron transport via bulk carriers. The integrated system combines multiple technologies to ensure safer marine transport of reduced iron.
“NYK secures AiP for subsea cable-laying vessel design” was originally created and published by Ship Technology, a GlobalData owned brand.
