The framework regulations § 58

§ 58 Warning and notification in connection with entry into safety zones

The operator shall alert a vessel that is in the process of entering a safety zone when it is not authorised to enter such area. The operator shall also alert vessels outside a safety zone if the vessels could constitute a safety risk to the petroleum activities.
If an object could constitute a safety risk to the petroleum activities, the operator shall alert the party responsible for the object, if possible.
The operator shall alert the Joint Rescue Coordination Centre and the Norwegian Ocean Industry Authority in the event of situations as mentioned in the first and second subsections, and which can result in a serious safety risk for the petroleum activities. The Ministry of Labour and Social Inclusion can stipulate warning procedures.
The operator shall also report violation of safety zones to the appropriate police authority and the Norwegian Ocean Industry Authority according to procedures stipulated by the Ministry of Labour and Social Inclusion.

The provision's intent is to prevent accidents and harmful effects, and protect facilities. The notification can take place in different manners, e.g. via radio, audio or light, and shall be included in the operator's emergency response scheme.
The intention of the second subsection is to have the party responsible for the object personally take necessary action. If the operator cannot notify the responsible party, and the object enters a safety zone or in some other manner constitutes a risk to the petroleum activities, Section 9-5 of the Petroleum Act is used.
The purpose of the third subsection is that public institutions shall have as much time as possible to implement necessary measures, which can contribute to reducing the risk.
As regards the fourth subsection, reference is made to the Regulations relating to police districts (in Norwegian only), which states what is the correct police authority. See also the Guidelines regarding Section 29 in the supplementary Management Regulations, which states what is the correct police authority.
