Subpart 147.01-Purpose and Delegation

§ 147.01-1 Purpose of safety zones.

Safety zones may be established around artificial islands and fixed structures being constructed, maintained, or operated on the Outer Continental Shelf to promote the safety of life and property on the islands and structures, their appurtenances and attending vessels, and on the adjacent waters within the safety zones. Regulations adopted for safety zones may extend to the prevention or control of specific activities and access by vessels or persons, and include measures to protect the living resources of the sea from harmful agents. The regulations do not encompass the operating equipment or procedures used in the drilling for and production of oil, gas, or other minerals, or the transportation of oil, gas, or other minerals by pipeline except as they relate to the safety of life and property on the islands and structures and on the waters adjacent

to the artificial islands and fixed structures or to the protection of the living resources of the sea within a safety zone from harmful agents.

§ 147.01-3 Delegation of authority.

The authority to establish safety zones and to issue and enforce safety zone regulations in accordance with the provisions of this part is delegated to district commanders. This authority may not be redelegated.

Subpart 147.03-Establishment of Safety Zones

§ 147.03-1 Initial action by the district

commander.

Whenever it comes to the attention of the district commander that a safety zone and regulations may be required concerning an artificial island or fixed structure being constructed, maintained, or operated on the Outer Continental Shelf or its appurtenances and attending vessels, or the adjacent waters, he may initiate appropriate inquiry to determine whether a safety zone and regulations should be established. In making this determination, the district commander considers all relevant safety factors, including existing or reasonably foreseeable congestion of vessels, the presence of unusually harmful or hazardous substances, and any obstructions within 500 meters of an artificial island or fixed structure. If the district commander determines that the circumstances warrant the establishment of a safety zone and regulations he takes action as he deems necessary consistent with the provisions of this part.
