§ 165.756 Regulated Navigation Area; Savannah River, Georgia.
(a) Regulated Navigation Area (RNA). The Savannah River between Fort Jackson (32 [degrees] 04.93' N, 081 [degrees] 02.19' W) and the Savannah River Channel Entrance Sea Buoy is a regulated navigation area when an LNG tankship in excess of heel is transiting the area or moored at the LNG facility. All coordinates are North American Datum 1983.
(b) Definitions. The following definitions apply to this section:
Bare Steerage Way means the minimum speed necessary for a ship to maintain control over its heading.
Bollard pull means an industry standard used for rating tug capabilities and is the pulling force imparted by the tug to the towline. It means the power that an escort tug can apply to its working line(s) when operating in a direct mode.
Direct Mode means a towing technique defined as a method of operation by which a towing vessel generates towline forces by thrust alone at an angle equal to or nearly equal to the towline, or thrust forces applied directly to the escorted vessel's hull.
Fire Wire means a length of wire rope or chain hung from the bow and stern of a vessel in port to allow the vessel to be towed away from the pier in case of fire; also called fire warp or emergency towing wire.
Heel means the minimum quantity of liquefied natural gas (LNG) retained in an LNG tankship after unloading at the LNG facility to maintain temperature, pressure, and/or prudent operations. A quantity of LNG less than five percent (5 %) of the LNG tankship's carrying capacity shall be presumed to be heel.
Indirect Mode means a towing technique defined as a method of operation by which an escorting towing vessel generates towline forces by a combination of thrust and hydrodynamic forces resulting from a presentation of the underwater body of the towing vessel at an oblique angle to the towline. This method increases the resultant bollard pull, thereby arresting and controlling the motion of an escorted vessel.
LNG tankship means a vessel as described in 46 CFR 154.
Made-up means physically attached by cable, towline, or other secure means in such a way as to be immediately ready to exert force on a vessel being escorted.
Make-up means the act of, or preparations for becoming made-up.
Operator means the person who owns, operates, or is responsible for the operation of a facility or vessel.
Savannah River Channel Entrance Sea Buoy means the aid to navigation labeled R W "T" Mo (A) WHIS on the National Oceanic and Atmospheric Administration's (NOAA) Nautical Chart 11512.
Standby means readily available at the facility and equipped to provide a ready means of assistance to maintain a safe zone around LNG tankships, provide emergency firefighting assistance, and aid the LNG tankship in the event of an emergency departure.
Underway means that a vessel is not at anchor, not made fast to the shore, or not aground.
(c) Applicability. This section applies to all vessels operating within the RNA, including naval and other public vessels, except vessels that are engaged in the following operations:
(1) Law enforcement, security, or search and rescue;
(2) Servicing aids to navigation;
(3) Surveying, maintenance, or improvement of waters in the RNA; or
(4) Actively engaged in escort, maneuvering, or support duties for an LNG tankship.
