ClassNK grants AiP to two MOL cable vessel designs

ClassNK has issued an Approval in Principle (AiP) for the designs of a cable jointing vessel and a cable burial vessel developed by Mitsui O.S.K. Lines Ltd (MOL). The certification demonstrates the designs’ feasibility from regulatory and safety perspectives.

In Japan, 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.

In response to this challenge, long-distance subsea DC transmission using cable jointing and burial vessels is regarded as an effective solution for achieving efficient power transmission.

ClassNK carried out a design review based on part O of its “Rules and Guidance for the Survey and Construction of Steel Ships”, as well as other relevant rules. ClassNK issued the AiP after it was confirmed that the prescribed requirements were met.
