The Port of Esbjerg in Denmark is considered the world's largest offshore wind port.
Types
Small oceanic ports
These are small port facilities to launch survey vessels used in an early stage of an offshore wind farm development.
Manufacturing ports
Large offshore wind turbine components are difficult to transport over land. Locating a manufacturing facility at a port is more desirable. Subcomponents and materials may be brought through roads or railways. After components are built, they are typically shipped to a marshaling port for the final assembly.
Marshaling ports
Marshaling ports (also known as staging ports) are used to collect and store wind turbine components prior to loading them onto wind turbine installation vessels. They are preferably located where there is unrestricted air draft to the wind farm site.
Operating and maintenance ports
Operating and maintenance ports house facilities and vessels that are required for ongoing operating and maintenance of offshore wind farms. This may include part warehouse, offices, and training facilities.

Europe
The six leading offshore wind ports in Europe service wind farms in the North Sea. Their respective countries signed the Ejsberg Declaration in 2022 in which they agreed to coordinate supply chain activities to optimize the manufacture and delivery of wind turbine components.

United States
As of 2021, offshore wind power in the United States was described as a "burgeoning" industry. At that time, a number of ports were proposing to build or convert facilities to handle the large components needed to build potential offshore wind farms.
On the East Coast, from north to south, there are operating or potential ports. In August 2025 the Trump administration's Department of Transportation withdrew or cancelled funding for many pro jects.
