The framework regulations § 47a

§ 47a Anchoring that can damage vulnerable resource values

Upon deployment of anchors and anchor lines that can cause mechanical damage to vulnerable environmental values, anchoring shall be carried out in a way that minimizes damage. Upon deployment of anchors the possibility of the facility shifting berth, shall be taken into account.
In the individual case, the operator shall assess what is the sufficient distance between vulnerable environmental values of significance and anchors and anchor lines, and implement risk-reducing measures to prevent damage to the environmental values.
Anchoring operations shall be monitored to ensure that anchoring causes the least possible damage to vulnerable environmental values.

Vulnerable environmental values mean, for example, corals and sponges.
Environmental values of significance mean, for example, coral reefs and/or coral forests of high quality and areas with a high density of sponges.
Examples of risk reducing measures are ROV assisted pre-deployment and retrieval of anchors, use of fiber lines in combination with buoyance buoys.
