Cable installation demand becomes over-concentrated around 2030

With the wind sector driving the subsea power cable market, a peak is anticipated in 2030 along with a supply crunch. Meanwhile, net zero targets are pushing the rise in interconnector demand.

‍

43 active CLVs and 29 cable facilities by 2030

The active cable-layer fleet is expanding to meet installation demand, with 12 new units to enter the market by 2028. At the same time, cable manufacturers are also adapting, with an additional nine production units by 2030.

‍

42% of array cable demand could be unmet

Almost 18,000km of array cable is likely to be laid by 2030, this could even reach 21,000km with adequate vessel supply. Yet, with a cumulative pipeline of 36,000km, this leaves a demand deficit of 42% that cannot be covered by the incumbent fleet.
