This subpart provides requirements for pollution equipment on deepwater ports.

(a) Each deepwater port must have a facility response plan that meets the requirements outlined in part 154, subpart F, of this chapter, and be approved by the cognizant Sector Commander, or MSU Commander with COTP and OCMI authority.

(b) The facility response plan must identify adequate spill containment and removal equipment for deepwater port-specific spill scenarios.

(c) Response equipment and material must be pre-positioned for ready access and use on board the deepwater port.

(a) Each oil and natural gas transfer system (OTS/NGTS) must include a relief valve that, when activated, prevents pressure on any component of the OTS/NGTS from exceeding its maximum rated pressure.

(b) The transfer system overflow or relief valve must not allow a discharge into the sea.

Each pipeline end manifold must have a shutoff valve capable of operating both manually and from the pumping platform complex.

Each floating hose string must have a blank flange and a shutoff valve at the vessel's manifold end.

Each oil and natural gas transfer line passing through a single point mooring buoy system must have a manual shutoff valve.

(a) Each oil and natural gas system, between a pumping platform complex and the shore, must have a system that can detect and locate leaks and other malfunctions, particularly in high-risk areas.

(b) The marine transfer area on an oil deepwater port must be equipped with a monitoring system in accordance with § 154.525 of this chapter.

(c) A natural gas deepwater port must be equipped with gas detection equipment adequate for the type of transfer system, including storage and regasification, used. The Commandant (CG-5P) will evaluate proposed leak-detection systems for natural gas on an individual basis.

(a) Each cargo transfer system must have an alarm to signal a malfunction or failure in the system.

(b) The alarm must sound automatically in the control room and:

(1) Be capable of being activated at the pumping platform complex;

(2) Have a signal audible in all areas of the pumping platform complex, except in areas under paragraph (b)(3) of this section;

(3) Have a high intensity flashing light in areas of high ambient noise levels where hearing protection is required under § 150.615 of this chapter; and

(4) Be distinguishable from the general alarm.

(c) Tankers calling on unmanned deepwater ports must be equipped with a transfer system alarm described in this section.

Each switch for activating an alarm, and each audio or visual device for signaling an alarm, must be identified by the words “Oil Transfer Alarm” or “Natural Gas Transfer Alarm” in red letters at least 1 inch high on a yellow background.

(a) Each deepwater port must have the following communications equipment:

(1) A system for continuous two-way voice communication among the deepwater port, the tankers, the support vessels, and other vessels operating at the deepwater port. The system must be usable and effective in all phases of a transfer and in all conditions of weather at the deepwater port;

(2) A means to indicate the need to use the communication system required by this section, even if the means is the communication system itself; and

(3) Equipment that, for each portable means of communication used to meet the requirements of this section, is:

(i) Certified under 46 CFR 111.105-11 to be operated in Group D, Class 1, Division 1 Atmosphere; and,

(ii) Permanently marked with the certification required in paragraph (a)(3)(i) of this section. As an alternative to this marking requirement, a document certifying that the portable radio devices in use are in compliance with this section may be kept at the deepwater port.

(b) The communication system of the tank ship mooring at an unmanned deepwater port will be deemed the primary means of communicating with support vessels, shore side, etc.

Each pumping platform complex must have enough curbs, gutters, drains, and reservoirs to collect, in the reservoirs, all oil and contaminants not authorized for discharge into the ocean according to the deepwater port's National Pollution Discharge Elimination System permit.
