ACTIONS
Technical and Management
Loading Arms, Cargo Pipes and Transfer Hoses
Loading arm installations should have a visual indication of the operating envelope (see Figure 10)
and/or be provided with alarms to indicate excessive range and drift.
Loading arms, cargo pipes and transfer hoses should conform to recognised standards and be
used only for substances for which they are suitable with regard to temperature, compatibility of
substances and working pressure or flow rate.
All new and replacement piping must be designed, fabricated, tested and maintained in accordance
with codes of practice developed by a recognised association. Piping must be tested for tightness and
all deficiencies must be eliminated before the piping is placed in service.
All cargo transfer hoses (see Figure 9) and piping must be adequately supported and protected from
physical damage. Piping must be painted or coated according to recognised industrial standards to
prevent corrosion.
For identification purposes, all piping at terminal facilities must be colour-coded.
Transfer piping spill containment to be provided. All oil transfer points of connection must be provided
with a spill containment system designed, constructed and maintained to contain discharges that
may occur from a hose or connection point rupture.
All piping must be tested for tightness. Tightness testing is required for piping 10 years after installation
and every 5 years thereafter.
All terminal facility transfer hoses must be marked with the following information:
• manufacturer’s name or trademark;
• identification with the standard specification of manufacture;
• products for which the hose may be used – or the marking for oil service;
• maximum allowable working pressure;
• month and year of manufacture;
• manufacturer’s serial number; and
• date of last test.
Hose ends must be blanked tightly when hoses are moved into position to be connected and also immediately
after they are disconnected and drained either into the vessel tanks or into suitable shore
receptacles before they are moved away from their connection.
Transfer hoses must be hydrostatically tested annually to 1.5 times the maximum allowable working
pressure to check their integrity. Electrical continuity test should be performed before, during and
after the pressure test.
