§150.300   What does this subpart do?

This subpart supplements the International Regulations for Prevention of Collisions at Sea, 1972 (72 COLREGS) described in subchapter D of this chapter, and prescribes requirements that:

(a) Apply to the navigation of all vessels at or near a deepwater port; and

(b) Apply to all vessels while in a safety zone, area to be avoided, or no anchoring area.

§150.305   How does this subpart apply to unmanned deepwater ports?

The master of any tanker calling at an unmanned deepwater port is responsible for the safe navigation of the vessel to and from the deepwater port, and for the required notifications in §150.325 of this part. Once the tanker is connected to the unmanned deepwater port, the master must maintain radar surveillance in compliance with the requirements of §150.310 of this part.

[USCG-2013-0397, 78 FR 39182, July 1, 2013]

§150.310   When is radar surveillance required?

A manned deepwater port's person in charge of vessel operations must maintain radar surveillance of the safety zone or area to be avoided when:

(a) A tanker is proceeding to the safety zone after submitting the report required in §150.325 in this part;

(b) A tanker or support vessel is underway in the safety zone or area to be avoided;

(c) A vessel other than a tanker or support vessel is about to enter or is underway in the safety zone or area to be avoided; or

(d) As described in the deepwater port security plan.

[USCG-1998-3884, 71 FR 57651, Sept. 29, 2006, as amended by USCG-2013-0397, 78 FR 39182, July 1, 2013]

A manned deepwater port's person in charge of vessel operations must advise the master of each tanker underway in the safety zone or area to be avoided of the following:

(a) At intervals not exceeding 10 minutes, the vessel's position by range and bearing from the pumping platform complex; and

(b) The position and the estimated course and speed, if moving, of all other vessels that may interfere with the movement of the tanker within the safety zone or area to be avoided.

§150.325   What is the first notice required before a tanker enters the safety zone or area to be avoided?

(a) The owner, master, agent, or person in charge of a tanker bound for a manned deepwater port must comply with the notice of arrival requirements in subpart C of part 160 of this chapter.

(b) The owner, master, agent, or person in charge of a tanker bound for a manned deepwater port must report the pertinent information required in §150.15(i)(4)(vi) of this part for the vessel, including:

(1) The name, gross tonnage, and draft of the tanker;

(2) The type and amount of cargo in the tanker;

(3) The location of the tanker at the time of the report;

(4) Any conditions on the tanker that may impair its navigation, such as fire, or malfunctioning propulsion, steering, navigational, or radiotelephone equipment. The testing requirements in §164.25 of this chapter are applicable to vessels arriving at a deepwater port;

(5) Any leaks, structural damage, or machinery malfunctions that may impair cargo transfer operations or cause a product discharge; and

(6) The operational condition of the equipment listed under §164.35 of this chapter on the tanker.

(c) If the estimated time of arrival changes by more than 6 hours from the last reported time, the National Vessel Movement Center (NVMC) and the port's person in charge of vessel operations must be notified of the correction as soon as the change is known.

(d) If the information reported in paragraphs (b)(4) or (b)(5) of this section changes at any time before the tanker enters the safety zone or area to be avoided at the deepwater port, or while the tanker is in the safety zone or area to be avoided, the master of the tanker must report the changes to the NVMC and port's person in charge of vessel operations as soon as possible.

[USCG-1998-3884, 71 FR 57651, Sept. 29, 2006, as amended by USCG-2013-0397, 78 FR 39182, July 1, 2013]

§150.330   What is the second notice required before a tanker enters the safety zone or area to be avoided?

When a tanker bound for a manned deepwater port is 20 miles from entering the port's safety zone or area to be avoided, the master of the tanker must notify the port's person in charge of vessel operations of the tanker's name and location.

§150.340   What are the rules of navigation for tankers in the safety zone or area to be avoided?

(a) A tanker must enter or depart the port's safety zone or area to be avoided in accordance with the navigation procedures in the port's approved operations manual as described in §150.15(i) of this part.

(b) A tanker must not anchor in the safety zone or area to be avoided, except in a designated anchorage area.

(c) A tanker may not enter a safety zone or area to be avoided in which another tanker is present, unless it has been cleared by the person in charge of the port and no other tankers are underway.

(d) A tanker must not operate, anchor, or moor in any area of the safety zone or area to be avoided in which the net under keel clearance would be less than 5 feet.

[USCG-1998-3884, 71 FR 57651, Sept. 29, 2006, as amended by USCG-2013-0397, 78 FR 39182, July 1, 2013]

§150.345   How are support vessels cleared to move within the safety zone or area to be avoided?

All movements of support vessels within a manned deepwater port's safety zone or area to be avoided must be cleared in advance by the port's person in charge of vessel operations.

return arrow Back to Top

§150.350   What are the rules of navigation for support vessels in the safety zone or area to be avoided?

A support vessel must not anchor in the safety zone or area to be avoided, except:

(a) In an anchorage area; or

(b) For vessel maintenance, which, in the case of a manned deepwater port, must be cleared by the port's person in charge of vessel operations.

return arrow Back to Top

§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.

§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.

2Not part of Port Installation.

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.

§150.385   What is required in an emergency?

In an emergency, for the protection of life or property, a vessel may deviate from a vessel movement requirement in this subpart without clearance from a manned deepwater port's person in charge of vessel operations if the master advises the port person in charge of the reasons for the deviation at the earliest possible moment.
