ClassNK issues General Design Approval (GDA) for Subsea Cable-Laying Vessel developed by NYK Line in International Shipping News 04/03/2026 ClassNK has issued a General Design Approval (GDA) for Subsea Cable-Laying Vessel developed by Nippon Yusen Kabushiki Kaisha (NYK Line). This approval verifies the vessel’s compliance with relevant rules at the detailed design level*1. The expansion of wind power generation utilizing offshore areas and surrounding islands with favorable wind conditions and relatively limited site constraints is expected as part of efforts to increase the share of renewable energy. However, regions suitable for wind power generation are often located far from major electricity demand centers, making the development and reinforcement of power transmission infrastructure a key challenge in delivering generated electricity to demand areas.

ClassNK carried out a design review of the vessel based on part O of its `Rules and Guidance for the Survey and Construction of Steel Ships,’ as well as other relevant rules, and issued a GDA after confirming compliance with the prescribed requirements. ClassNK will continue to contribute to the widespread adoption of offshore wind power generation by supporting new technology development and social implementation, including through safety assessments.
