# 150.355 How are other vessels cleared to move within the safety zone?

(a) Clearance by a manned deepwater port's person in charge of vessel operations is required before a vessel, other than a tanker or support vessel, enters the safety zone.

(b) The port's person in charge of vessel operations may clear a vessel under paragraph (a) of this section only if its entry into the safety zone would not:

(1) Interfere with the purpose of the deepwater port;

(2) Endanger the safety of life, property, or environment; or

(3) Be prohibited by regulation.

(c) At an unmanned deepwater port, such as a submerged turret landing (STL) system, paragraphs (a) and (b) of this section apply once a tanker connects to the STL buoy.
