Denmark has established a Coastal Radar Surveillance System (in the following referred to as “KYRA”) for Maritime Surface Surveillance. As Denmark is implementing a number of windmill projects at sea it is necessary to supplement KYRA with a number of “gap-filler” radars to compensate for the influence from the windmills. This means that the gap-filler radars must be able to detect the same objects as the radars in service in KYRA. The gap-filler radars must be able to operate uninterrupted under severe weather conditions offered at the locations of the windmill installations at sea within the Danish waters, including but not limited to the North Sea, Kattegat and the Baltic Sea. DALO intends to use the Products, Spare Parts and Services of the Agreement to compensate for the negative influence that the current and future windmill projects will have on KYRA. This means that the Agreement will be used individually for each windmill project. Previous modification: Offshore installation and training for offshore installationswas not included in the originalt tender, hence the need to include in order to install gap-filler radars at wind farms located offshore. New modification: in order for the gap-filler radars to fit to a specific wind farm, different sprareparts and works has turned out to be needed including an on-site installation visit.
