1 Regulation 6 of SOLAS chapter
XI-2 requires ships to be provided with a ship security alert
system. Section A/9 of the International Ship and Port Facility Security (ISPS) Code requires ships to carry a ship security
plan. Performance standards for ship security alert systems are given
in resolution MSC.147(77). This Circular
gives guidance on the design of ship security alert systems provided
to comply with the SOLAS regulation.
2 The intent of the ship security alert system
is to send a covert signal or message from a ship which will not be
obvious to anyone on the ship who is not aware of the alert mechanism.
It is of use therefore in circumstances where a ship wishes to inform
a person ashore of a problem with a minimum number of the persons
onboard aware of the action. The procedures for the security alert
are agreed with the ship's Administration as part of the ship security
plan and ideally should be individual to the ship. It is not intended
that the ship security alert procedures should be to an internationally
agreed standard or conform to any particular format for all ships.
3 Possible methods of achieving the alert are
as follows:
-
.1 a system may employ proprietary tracking equipment
provided by traffic service providers. The ship then carries a concealed
equipment box working over a satellite system on its upper deck which
transmits a position report at, typically, 6-hourly intervals. Interruption
of power to the equipment or arming of the equipment by means of sensors
or manual buttons causes the equipment to transmit a different format
of position report. The tracking service providers monitor the transmission
reports and inform the Company when the transmission format changes;
-
.2 a system may utilise modifications of GMDSS
equipmentfootnote. Some GMDSS equipment
is not very suitable for modification as it is optimised for “all
station” calling and may involve manual setting of frequencies
etc and provides confirmation on the ship of messages sent. In these
types of systems the ship security alert contains identifiers to ensure
that it is not possible to confuse it with a GMDSS distress, urgency
or safety alert; and
-
.3 a system may utilise the exchange of messages
containing key words between a ship and, typically, the Company. These
messages may be by speech or data communications. Ship equipment which
may be used includes cellular phones in coastal areas and satellite
services away from coastal areas. It may be possible to use GMDSS
VHF/MF/HF equipment in areas where there are coastal facilities for
receiving addressed calls.
This list is not intended as exhaustive and is not intended
to inhibit future developments.
4 The ship security alert system requires two
activation points, one of which should be on the bridge. These will
typically be fixed or portable telephone handsets, fixed or portable
keypads or fixed or portable buttons.
5 Measures should be incorporated in the activation
points to avoid their inadvertent operation and the generation of
false alerts.
