ship or shore cargo systems, for example a jumper hose at the
end of a ramp serving a pontoon berth.
A tanker should attest that any hoses that it provides are certified,
fit for purpose, in good physical condition and have been pressure
tested.
Details of the various inspections and tests are given in the
following sections.
Visual Examination
A visual examination should consist of:
Examining the hose assembly for irregularities in the outside
diameter, e.g. kinking.
Examining the hose cover for damaged or exposed
reinforcement or permanent deformation.
Examining the end fittings for signs of damage, slippage or
misalignment.
A hose assembly exhibiting any of the above defects should be
removed from service for more detailed inspection. When a hose
assembly is withdrawn from service following a visual inspection,
Pressure Test (Integrity Check) ึ
the reason for withdrawal and the date should be recorded.
Hose assemblies should be hydrostatically tested to check their
integrity. The intervals between tests should be determined in
accordance with service experience, but in any case should not
be more than twelve months. Testing intervals should be
shortened for hoses handling particularly aggressive products or
products at elevated temperatures.
Hoses for which the rated pressure has been exceeded must be
removed and re-tested before further use.
A record should be kept of the service history of each hose
assembly.
The recommended method of testing is as follows:
(i) Lay out the hose assembly straight on level supports which
allow free movement of the hose when the test pressure is
applied. Conduct an electrical continuity test.
(ii) Seal the hose by bolting blanking-off plates to both ends,
one plate to be fitted with a connection to the water pump
and the other to be fitted with a hand operated valve to
release air through a vent. Fill the hose assembly with
water until a constant stream of water is delivered through
the vent.
(iii) Connect the test pump at one end.
(iv) Measure and record the overall length of the hose
assembly. Slowly increase the pressure up to the Rated
Working Pressure.
