This Chapter deals with communications required between the tanker and the shore,
including pre-arrival communications between the tanker and local authorities and
between the tanker and the terminal. It addresses communication exchanges
between the ship and the terminal before berthing and before and during cargo,
ballast or bunkering operations, including emergency communication procedures.

22.1 Procedures and Precautions

22.1.1 Communications Equipment

Telephone and portable VHF/UHF and radiotelephone systems should
comply with the appropriate safety requirements.

The provision of adequate means of communication, including a backup
system between ship and shore, is the responsibility of the terminal.
ึ
Communication between the Responsible Officer and the Terminal
Representative should be maintained in the most efficient way.

When telephones are used, they should be continuously manned by
persons, on board and ashore, who can immediately contact their
superior. Additionally, it should be possible for that superior to override all
calls.

When VHF/UHF systems are used, units should preferably be portable
and carried by the Responsible Officer on duty and the Terminal
Representative, or by persons who can contact their respective superior
immediately. Where fixed systems are used, they should be continuously
manned.

The selected system of communication, together with the necessary
information on telephone numbers and/or channels to be used, should be
recorded on an appropriate form. This form should be signed by both ship
and shore representatives.

22.1.2 Communications Procedures

To ensure the safe control of operations at all times, it should be the
responsibility of both parties to establish, agree in writing and maintain a
reliable communications system.

Before loading or discharging commences, the system should be tested.
A secondary standby system should also be established and agreed.
Allowance should be made for the time required for action in response to
signals.

Signals should be agreed for:

Identification of ship, berth and cargo.
Stand by.
