The global marine cable market is estimated to reach 18 million dollars in 2030, growing at a CAGR of 5.2%, according to Metastat. While it is not as strong as in other cable markets like renewables, this pace is still an indication of steady, confident growth.

The market can be divided into several segments:

• Vessel and shipboard cables used on boats, yachts, and commercial ships

• Offshore and oil and gas cables used in offshore oil rigs and wind farms

• Submarine subsea cables, including power cables for offshore wind farms and telecom subsea cables. Subsea hybrid power + fiber cables used in observatories and marine research also fall into this category.

• Shore-power cables for dock interfaces (usually flexible, portable, and of a lesser voltage than all other categories, 120–480V).

By installation environment, the marine cable and connector market is segmented into beach joint 1, beach joint 2, burial, and free lay. Beach joints 1 and 2 describe nearshore landing sections where subsea cables transition from land to sea; burial refers to cables installed beneath the seabed, and freelay refers to cables laid directly on the seabed without burial in deeper waters where external risk is lower.

The marine cable market is one of the few where Europe dominates, as it is a leader in offshore wind energy and shipbuilding. Strong investments in the Asia Pacific market will likely place it ahead of competitors in the years to come.

The factors driving market growth include offshore wind expansion, growth in data centre and hyperscaler infrastructure, and subsea power.
