Status message

There is 1 rule appearing in the Federal Register for 33 CFR 154. View below or at eCFR (GPOAccess)
§ 154.810 Vapor line connections.
(a) A remotely operated cargo vapor shutoff valve must be installed in the vapor collection line between the facility vapor connection and the nearest point where any inerting, enriching, or diluting gas is introduced into the vapor collection line or where a detonation arrester is fitted. The valve must:
(1) Close within thirty (30) seconds after detection of a shutdown condition by a component required by this subpart;
(2) Close automatically if the control signal is lost;
(3) Activate an alarm when a signal to shut down is received;
(4) Be capable of manual operation or manual activation;
(5) Have a local valve position indicator or be designed so that the valve position can be readily determined from the valve handle or valve stem position; and
(6) If the valve seat is fitted with resilient material, not allow appreciable leakage when the resilient material is damaged or destroyed.
(b) Except when a vapor collection arm is used, the last 1.0 meter (3.3 feet) of vapor piping before the facility vapor connection must be:
(1) Painted red/yellow/red with:
(i) The red bands 0.1 meter (0.33 feet) wide, and
(ii) The middle yellow band 0.8 meter (2.64 feet) wide; and
(2) Labeled “VAPOR” in black letters at least 50 millimeters (2 inches) high.
(c) Each facility vapor connection flange must have a permanently attached 0.5 inch diameter stud at least 1.0 inch long projecting outward from the flange face. The stud must be located at the top of the flange, midway between bolt holes, and in line with the bolt hole pattern.
(d) Each hose used for transferring vapors must:
(1) Have a design burst pressure of at least 25 psig;
(2) Have a maximum allowable working pressure of at least 5 psig;
(3) Be capable of withstanding at least 2.0 psi vacuum without collapsing or constricting;
(4) Be electrically continuous with a maximum resistance of ten thousand (10,000) ohms;
(5) Have flanges with:
(i) A bolt hole arrangement complying with the requirements for 150 pound class ANSI B16.5 (incorporated by reference; see§ 154.106) flanges, and
(ii) One or more 0.625 inch diameter holes in the flange located midway between bolt holes and in line with the bolt hole pattern;
(6) Be abrasion resistant and resistant to kinking; and
(7) Have the last 1.0 meter (3.3 feet) of each end of the vapor hose marked in accordance with paragraph (b) of this section.
(e) Vapor hose handling equipment must be provided with hose saddles which provide adequate support to prevent kinking or collapse of hoses.
(f) Fixed vapor collection arms must:
(1) Meet the requirements of paragraphs (d)(1) through (d)(5) of this section;
(2) Have the last 1.0 meter (3.3 feet) of the arm marked in accordance with paragraph (b) of this section.
(g) The facility vapor connection must be electrically insulated from the vessel vapor connection in accordance with section 6.10 of the OCIMF International Safety Guide for Oil Tankers and Terminals (incorporated by reference; see § 154.106).
(h) A vapor collection system fitted with an enriching system that operates at a positive gauge pressure at the facility vapor connection must be fitted with:
(1) A manual isolation valve between each facility vapor connection and the remotely operated cargo vapor shutoff valve required by paragraph (a) of this section; and
(2) A means to prevent backflow of enriched vapor to the vessel's vapor collection system.
