Floating wind and port demand: the basics

How floating offshore wind connects to ports, cables, moorings, vessels, fabrication areas and long-term operations work. With real project examples.
What makes floating wind different
- Floating wind uses floating foundations rather than fixed foundations embedded in the seabed, allowing projects in deeper waters.
- Floating projects require large components, mooring systems, dynamic cables, tow-out activity and specialist port logistics.
- The supply chain often touches oil and gas skills: marine operations, heavy engineering, offshore safety, project controls and vessel coordination.
- Scotland has committed to 40GW of offshore wind by 2040. Much of that will be floating.
Real projects to watch
- Buchan Offshore Wind: 1GW, 75km northeast of Fraserburgh, onshore consent granted May 2026, cable to Peterhead substation.
- Caledonia (Ocean Winds): 2GW fixed-bottom, onshore consent granted same day as Buchan.
- Salamander: stepping-stone project to ScotWind developments, focused on Scottish supply chain development.
- Hywind Scotland: the world's first commercial-scale floating wind farm, off Peterhead, operational since 2017.
Why ports matter
- Ports may support component storage, assembly, marshalling, mobilisation, crew transfer, service vessels and operations-and-maintenance activity.
- Quayside depth, load capacity, laydown area, road access and local supplier depth all affect how useful a port is to offshore wind work.
- Aberdeen South Harbour (8km quayside, 300m vessels, 15m depth) is explicitly designed for this market.
- Peterhead, Fraserburgh and other North East Scotland ports all have potential roles in the floating wind supply chain.
