Floating offshore wind is moving from concept to deployment, but the UK still lacks the port infrastructure needed to turn that pipeline into actual capacity, according to a new infrastructure report from financial services firm Heligan, as reported by Splash247.
According to Heligan, floating projects, forecast to exceed 10GW-15GW, could account for about one-third of UK offshore wind capacity by 2050 and deliver 175TWh a year. The report also points to the government-industry Floating Offshore Wind Taskforce, which has mapped a £47bn ($63.3bn) opportunity and up to 97,000 jobs.
Port Infrastructure Lags Policy Ambition
Heligan stated that supply and logistics are not keeping pace with policy ambition. The company said no UK port is currently ready for commercial floating wind deployment, creating a bottleneck just as auctions and lease awards begin to translate into project pipelines. The industry has already secured up to 4.5GW through awards including the Celtic Sea leasing round completed in 2025.
"Delivering this future will require industrial-scale infrastructure. Yet, the UK is at risk of falling behind without the infrastructure to deliver at scale. No UK port is currently equipped to support commercial floating wind deployment, creating a critical bottleneck," said Andrew Dickinson, head of infrastructure services at Heligan.
Investment Commitments and Upgrades Needed
Investments are starting to move. The Port of Cromarty Firth is receiving £55m ($74m) for floating wind manufacturing, while ABP has committed more than £500m ($673m) to turn Port Talbot into a Celtic Sea hub. Heligan said as many as 11 ports may need to be upgraded by 2030, with about £3.5bn ($4.7bn) required in total.
| Key Metric | Value |
|---|---|
| Forecast UK floating capacity by 2050 | 10GW–15GW |
| Share of UK offshore wind capacity by 2050 | ~one-third |
| Annual generation by 2050 | 175TWh |
| Taskforce-mapped opportunity | £47bn ($63.3bn) |
| Jobs mapped by taskforce | up to 97,000 |
| Capacity already secured | up to 4.5GW |
| Ports needing upgrade by 2030 | as many as 11 |
| Total upgrade cost | ~£3.5bn ($4.7bn) |
| Cromarty Firth funding | £55m ($74m) |
| ABP Port Talbot commitment | >£500m ($673m) |
European Competition for Port Capacity
The pressure is not limited to the UK. EU-backed Green Deal Industrial Plan reforms and national support schemes are accelerating port investment across Europe, setting up competition for assembly space, modular fabrication, and export capacity. This creates a competitive landscape for UK ports seeking to handle floating wind components.
Changing Deal Market
Heligan noted that the shift is already changing the deal market. Dickinson added that floating wind is entering a phase that will attract consolidators from marine engineering, offshore energy, and modular construction, while permitting and biodiversity expertise will become more valuable as compliance becomes a gatekeeper for project delivery. For commodity traders and procurement teams, these infrastructure commitments signal sustained demand for steel, marine construction materials, and specialised fabrication capacity tied to UK and European offshore wind build-out.
