MOL Receives Approval in Principle for Submarine Power Cable Vessels

MOL's Innovative Steps in Submarine Power Cable Technology

Mitsui O.S.K. Lines, Ltd. (MOL), led by President Takeshi Hashimoto and headquartered in Minato, Tokyo, has proudly announced that it has received Approval in Principle (AiP) from the ClassNK, a prominent certification body in the maritime industry, for its designs related to submarine power cable connection and burial vessels.

The Importance of Submarine Power Cables

In regions like Hokkaido, where wind power generation thrives, there exists a substantial distance from major power consumption areas, necessitating significant enhancements in power transmission. Long-distance direct current submarine transmission technology has emerged as an effective solution to transport substantial amounts of electricity, not just improving power systems but also significantly benefiting offshore wind power initiatives.

MOL is collaborating with major industry players including Sumitomo Electric Industries, Furukawa Electric, and Nippon Yusen to develop foundational technologies for new cable-laying vessels under a project funded by the New Energy and Industrial Technology Development Organization (NEDO).

Achievements in Vessel Development

As part of this pioneering endeavor, MOL is focused on the technological progression of its connection and burial vessels. Securing the AiP stands as a substantial achievement and a testament to the innovative capabilities of the company.

The Jules Verne-esque concept of connecting and burying submarine cables is crucial due to the challenges inherent in laying long-distance cables. The laying vessels, termed 'connection vessels', are crucial, as they are responsible for joining segments of submarine cables laid progressively. Additionally, to prevent damage to these cables due to anchoring or fishing nets, it's essential to bury them under the seabed. This burial process is primarily executed using Remotely Operated Vehicles (ROVs), with dedicated vessels designed to support ROV operations classified as 'burial vessels'.

The AiP confirms that the preliminary design meets all specified regulations, confirming adherence to crucial technical requirements and safety standards. The approval underscores MOL's commitment to advancing maritime engineering and technology.

Commitment to Renewable Energy

The MOL Group has identified offshore wind energy as a primary focus area in its management strategy dubbed "BLUE ACTION 2035". Through the development of vessels designated for submarine power cable installation, MOL is set to contribute significantly to the proliferation of renewable energy and the transition towards a decarbonized society.

Looking Ahead

As the global landscape shifts towards sustainable energy, MOL's commitment to developing efficient and safe vessels for submarine power cable transmission is more crucial than ever. The company's collaboration with esteemed industry partners positions it as a leader in innovative maritime solutions for renewable energy.

This strategic initiative not only enhances MOL's standing in the shipping industry but also aligns with broader global goals of increasing renewable energy ratios and fostering a sustainable future for generations to come.
