ClassNK has granted an Approval in Principle (AiP) for the designs of a cable jointing vessel and a cable burial vessel created by Mitsui O.S.K. Lines, Ltd. This certification confirms the designs meet regulatory and safety standards, highlighting their feasibility for practical application.
In Japan, there is an increasing focus on boosting wind power generation by using offshore locations and nearby islands with optimal wind conditions and minimal site restrictions. This move is part of broader efforts to enhance the renewable energy share in the nation's energy portfolio.
Reinforcement of power transmission infrastructure
The challenge of connecting regions with ideal wind power conditions to major electricity demand centres remains significant.
These areas are frequently distant from the main hubs of electricity consumption, making the development and strengthening of power transmission infrastructure crucial for effectively delivering generated electricity.
Long-distance subsea DC transmission
AiP was granted following confirmation that all specified requirements were fulfilled
To tackle this challenge, the adoption of long-distance subsea DC transmission, facilitated by cable jointing and burial vessels, is seen as a particularly effective solution for ensuring efficient power transfer.
ClassNK conducted a design review of these vessels, adhering to part O of its "Rules and Guidance for the Survey and Construction of Steel Ships" along with other pertinent guidelines. The AiP was granted following confirmation that all specified requirements were fulfilled.
Supporting offshore wind power generation
ClassNK intends to continue supporting the advancement and societal integration of offshore wind power generation technologies. This includes undertaking rigorous safety assessments to ensure the adaptation of innovative solutions within the sector.
By doing so, ClassNK aims to facilitate the broader adoption of offshore wind energy, contributing to a sustainable energy future.
