§150.380   Under what circumstances may vessels operate within the safety zone or area to be avoided?

(a) Table 150.380(a) of this section lists both the areas within a safety zone where a vessel may operate and the clearance needed for that location.

Table 150.380(a)—Regulated Activities of Vessels at Deepwater Ports

Key to regulated activities for Table 150.380(a):

C—Movement of the vessel is permitted when cleared by the person in charge of vessel operations.

D—Movement is not restricted, but recommended transit speed not to exceed 10 knots. Communication with the person in charge of vessel operations.

F—Only in an emergency. Anchoring will be avoided in a no anchoring area except in the case of immediate danger to the ship or persons on board.

N—Not permitted.

P—Transit is permitted when the vessel is not in the immediate area of a tanker, and when cleared by the vessel traffic supervisor.

R—Permitted only if determined that operation does not create unacceptable risk to personnel safety and security and operation. For transiting foreign-flag vessels, the requirement for clearance to enter the area to be avoided and no anchoring area is advisory in nature, but mandatory for an anchorage area established within 12 nautical miles.

(b) If the activity is not listed in table 150.380(a) of this section, or otherwise provided for in this subpart, the Sector Commander's, or MSU Commander's, with COTP and OCMI authority permission is required before operating in the safety zone or regulated navigation area.
