The DEFRA/DfT Clean Maritime Plan includes grant funding for zero-emission vessel demonstrators - including electric and hydrogen CTVs.

The UK Offshore Support Vessel Finance Market
The UK offshore support vessel sector is undergoing its largest expansion in a generation, driven by the accelerating build-out of offshore wind capacity across the North Sea, Irish Sea, and English Channel. The UK's offshore wind fleet - already the world's largest - is set to more than double in installed capacity by 2030, creating extraordinary demand for crew transfer vessels (CTVs), service operation vessels (SOVs), and platform supply vessels (PSVs) to support construction, commissioning, and long-term operations and maintenance (O&M) activity.
Crew transfer vessels are the fastest-growing vessel category. With over 1,000 CTVs expected in UK waters by 2030 and typical new-build values ranging from £1m to £4m for aluminium-hulled 24m vessels, the financing requirement for the sector runs into billions of pounds. At Doulton Bridging Finance, we are active in this market daily - placing CTV and OSV finance with lenders ranging from the clearing banks (HSBC, NatWest, Lombard) through to specialist challenger banks (Hampshire Trust, Shawbrook) and large-ticket asset lenders (Siemens Financial Services for SOVs and PSVs above £1m).

High-speed aluminium or composite catamarans, typically 20–27m, serving offshore wind turbine maintenance crews. The most active segment of the OSV finance market. Lenders understand long-term O&M contracts with tier-one wind operators as quality security. CTV Finance Guide →
