PRECAUTIONS ON SHIP AND TERMINAL DURING CARGO HANDLING

24.7.5 Ship and Shore Cargo and Bunker Pipelines not in Use
24.9.1ื่อการศึกษาเท่านั้น---
The tightness of valves should not be relied upon to prevent the escape
or seepage of oil. All shore pipelines, loading arms and hoses not in use
at a berth must be securely blanked.

All ship’s cargo and bunker pipelines not in use must be securely blanked
at the manifold. The stern cargo pipelines should be isolated from the
tanker’s main pipeline system forward of the aft accommodation by
blanking or by the removal of a spool piece.

24.8 Fire-Fighting Equipment

When a tanker is alongside a berth, fire-fighting equipment is to be ready for
immediate use.

On board the ship, this is normally achieved by having fire hoses with spray/jet
nozzles connected run out forward and aft of, and adjacent to, the manifold in use.
Having a portable dry chemical powder extinguisher available near the manifold
provides additional protection against small flash fires.

On the jetty, fire-fighting equipment should be ready for immediate use. While this
may not involve the rigging of fire hoses, the preparations for emergency operation of
ึ
the fire-fighting equipment should be apparent and communicated to the tanker.
Consideration should be given to having portable extinguishers available for use
adjacent to the jetty manifold area.

24.9 Proximity to Other Vessels

Tankers at Adjacent Berths
Flammable concentrations of petroleum gas may be encountered if
another tanker at an adjacent berth is conducting cargo or ballast
handling, purging, tank cleaning or gas freeing operations. In such
circumstances, appropriate precautions should be taken as described in
Section 24.1.

24.9.2 General Cargo Ships at Adjacent Berths

It is unlikely that general cargo ships will be able to comply as fully as
tankers with the safety requirements relating to possible sources of
ignition, such as smoking, naked lights, cooking and electrical equipment.

Accordingly, when a general cargo ship is at a berth in the vicinity of a
tanker that is loading or discharging volatile petroleum, loading
non-volatile petroleum into tanks containing hydrocarbon vapour,
ballasting tanks containing hydrocarbon vapour, or purging or gas freeing
after the discharge of volatile petroleum, it will be necessary for the
terminal to evaluate any consequential safety hazards and to take
precautions additional to those set out in this Chapter. Such precautions
should include inspecting the general cargo ship involved and clearly
defining the precautions to be taken on board that ship.
