# §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](/cfr/33/127.003.md)); 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.
