INTERNATIONAL SAFETY GUIDE FOR OIL TANKERS AND TERMINALS

Hose assemblies should be visually inspected on a regular basis.
When hose assemblies are in constant or frequent use, the assembly

should be inspected before each loading/unloading operation. Hose
assemblies subject to infrequent use should be inspected each time
they are brought into use.

18.2.11 Handling, Lifting and Suspending
Hoses should always be handled with care and should not be dragged
over a surface or rolled in a manner that twists the body of the hose.
Hoses should not be allowed to come into contact with a hot surface such
as a steam pipe. Protection should be provided at any point where
chafing or rubbing can occur.

Lifting bridles and saddles should be provided. The use of steel wires in

not be lifted at a single point with ends hanging down, but should be
supported at a number of places so that they are not bent to a radius less
than that recommended by the manufacturer.

Excessive weight on the ship’s manifold should be avoided. If there is an
excessive overhang, or the ship’s valve is outside the stool support,
additional support should be given to the manifold. A horizontal curved
plate or pipe section should be fitted at the ship’s side to protect the hose

from sharp edges and obstructions. Adequate support for the hose when
connected to the manifold should be provided. Where this support is via a
single lifting point, such as a derrick, the hose string should be supported
by bridles or webbing straps. Some hoses are specifically designed to be
unsupported.

18.2.12 Adjustment During Cargo Handling Operations
As the tanker rises or falls as a result of tide or cargo operations, the
hose strings should be adjusted so as to avoid undue strain on the hoses,

connections and ship’s manifold and to ensure that the radius of
curvature of the hose remains within the limits recommended by the

18.2.13 Submarine and Floating Hose Strings
Hoses in service at offshore mooring installations should be inspected
periodically.

Particular attention should be paid to kinked or damaged sections, oil
seepage from the hose flange areas, heavy marine growth and scuffing
on the seabed. Where hose strings are lowered and raised repeatedly
from the seabed, care should be taken to avoid damage caused by chains
and lifting plates.

Particular care should be taken when lowering hose strings to avoid them
coiling down. Dragging of hoses over the seabed should be minimised.

Before attempting to lift a hose string on board, the Responsible Officer
should check that the total weight involved does not exceed the safe
working load of the ship’s derrick or crane. The terminal should advise
the total weight of the hose string to be lifted in relation to the height of
the lift, which could be as much as 8 metres above deck level for a
