Section 127.1102 - Transfer hoses and loading arms(a) Each hose within the marine transfer area for LHG used for the transfer of LHG or its vapors to or from a vessel must-(1) Be made of materials resistant to each LHG transferred, in both the liquid and vapor state (if wire braid is used for reinforcement, the wire must be of corrosion-resistant material, such as stainless steel);(2) Be constructed to withstand the temperature and pressure foreseeable during transfer, with a MAWP not less than the maximum pressure to which it may be subjected and at least 1030 kPa gauge (149.4 psig);(3) Be designed for a minimum bursting pressure of a least five times the MAWP;(4) Have- (i) Full-threaded connections;(ii) Flanges that meet ASME B16.5-2020 (incorporated by reference, see § 127.003 ); or(iii) Quick connect couplings that are acceptable to the Commandant;(5) Be adequately supported against the weight of its constituent parts, the LHG, and any ice formed on it;(6) Have no kinks, bulges, soft spots, or other defects that will let it leak or burst under normal working pressure; and(7) Have a permanently attached nameplate that indicates, or otherwise be permanently marked to indicate- (i) Each LHG for which it is suitable;(ii) Its MAWP at the corresponding service temperature; and(iii) If used for service at other than ambient temperature, its minimum service temperature.(b) Each loading arm used for the transfer of LHG or its vapor must- (1) Be made of materials resistant to each LHG transferred, in both the liquid and vapor state;(2) Be constructed to withstand the temperature and pressure foreseeable during transfer;(3) Be adequately supported against the weight of its constituent parts, the LHG, and any ice formed on it;(4) Be provided with an alarm to indicate when it is approaching the limits of its extension, unless the examined Operations Manual requires a person to perform the same function; and(5) Have a permanently attached nameplate that indicates, or otherwise be permanently marked to indicate- (i) Each LHG it may handle;(ii) Its MAWP at the corresponding service temperature; and,(iii) If it is used for service at other than ambient temperature, its minimum service temperature.CGD 88-049, 60 FR 39796, Aug. 3, 1995, as amended by USCG-2019-0444, 87 FR 5691, Feb. 2, 2022
