On February 13, NYK completed the basic design of a cable-laying vessel being developed for the construction of a long-distance subsea direct current transmission network off Japan and obtained General Design Approval from ClassNK for the vessel’s basic design.
NYK is participating in a four-company consortium with Sumitomo Electric Industries, Furukawa Electric, and Mitsui O.S.K. Lines as part of a NEDO-sponsored project to develop advanced cable protection methods and specialized cable-laying vessels.
This is part of NEDO’s RIGHT project, which aims to develop high-voltage direct current (HVDC) transmission technologies by multiplexing direct current transmission lines from wind power generation, by ensuring proper protection control and power flow control for reliable and efficient transmission . Together with Sumitomo Electric and with the cooperation of Furukawa Electric, NYK has been responsible for developing the cable-laying vessel.
With the completion of the vessel’s basic design and the acquisition of GDA from ClassNK, NYK has achieved its initial objectives within this NEDO-supported project. Moving forward, NYK will continue contributing to the realization of a decarbonized society through the advancement of technologies essential for subsea DC transmission.
