EQUIPMENT

equipment within a terminal is described in Section 4.4.2.พาณิชย

This Chapter describes equipment that is provided by the terminal at the ship/shore

Considerable emphasis is placed on ensuring that ship and shore remain
electrically isolated, and on the means of achieving isolation.

17.1 Electrical Equipment

The classification of hazardous zones for the installation or use of electrical
ึ

Terminals should ensure that any electrical equipment is provided in accordance with
a site specific area electrical classification drawing, which shows hazardous zones at
the berths in plan and elevation.

Terminals should identify the zones and establish the type of equipment that is to be
installed within each zone. National legislation, international standards and company
specific guidelines, where available, are all to be complied with. A planned
maintenance system should address the continued integrity of the equipment
installed, and ensure it remains able to meet zone requirements.

Personnel carrying out maintenance on equipment within hazardous zones should be
trained and certified as competent to carry out the work. Certification may be by
internal process or as required by regulatory bodies. All electrical maintenance
should be carried out under the control of a Permit to Work system (see
Section 19.1.3).

17.2 Fendering

Fendering systems at each berth should be engineered to suit the range of ship
sizes and types that use the berth and should be capable of withstanding expected
loads without causing damage to the ship. The design should take account of the
method of operating the berth, with particular reference to the use or non-use of
tugs.

In calculating the berthing energy to be absorbed by the fendering system, the speed
at which a ship closes with the berth is the most significant of all factors. Energy is

calculated as a function of mass and the square of the speed (E= / mV ). (See

Section 15.6.2.)
The spacing of the fenders should allow the ship to lie alongside, with the fenders on
the parallel sides of the ship, at all freeboards and all expected heights of the tide.
