During the construction phase, the Danish Maritime Authority will establish a protective zone of 200 metres on both sides of the cable and/or pipeline lay-out, which applies from its publication in Notices to Mariners. In the protective zone, anchoring, dredging, boulder fishing and using dragging gear are prohibited. The permanent protective zone is established by drawing the submarine cable or the pipeline in the chart.
The protective zone is established in pursuance of order no. 939 of 27 November 1992 on protection of submarine cables and submarine pipelines (the cable order), which does however not apply within the territorial waters of a port. The main purpose of the protective zone is to protect the interests of the submarine cable or the pipeline owner.
Submarine works or activities must not be made within the protective zones of submarine cables or pipelines without previous agreement with the submarine cable or pipeline owner. Details about submarine cables and pipelines in the area can be sought from the register of pipelines www.ler.dk or from the pipeline owner. Submarine cables can also be seen on www.dkcpc.dk (Danish Cable Protection Committee)
