Wilhelminahaven is one of four harbor basins within the Eemshaven port complex, situated adjacent to Julianahaven in the Netherlands.

The basin is purpose-built for energy-related cargo handling, measuring approximately 1,200 meters long, 275 to 300 meters wide, and 14. 0 meters deep.

Its quays serve distinct functions: the northern quay (525 m) is dedicated to handling and converting liquefied natural gas, the southern quay (450 m) is used for unloading coal carriers, and the eastern quay handles gypsum, biomass, and fly ash.

The harbor has also served as a base for offshore wind installation vessels, supporting major North Sea wind projects.

Eemshaven as a whole is a significant energy hub, with an installed capacity of 8,000 MW and accounting for roughly one-third of the Netherlands' total energy production.
