Emergency procedures must be drawn up for closing electricity producing systems in case a ship is on collision course with the system. Defence Command Denmark (the Naval Staff) must have direct contact with the operational centre of the system.
Base and wings:
The Danish Maritime Authority demands that the base for offshore wind turbines is designed in a collision-friendly manner so that as little damage as possible occurs in case of a collision.
The distance between the surface of the sea and the lower tip of the wing must be at least 20 metres in relation to the HAT (highest astronomical tide).
Distinction is made between navigation in and around offshore wind farms during the construction and the operational phase, respectively. During the construction phase, a work area will be established in which all unauthorised navigation, fishing, etc. are prohibited. In general, offshore wind farms in Denmark are open for free navigation during the operational phase. Please observe that this is not always the case with other countries' offshore wind farms.
