12.1 Paragraph 4.4.1 of the Revised performance
standards provides that when a ship is undergoing repairs, modifications
or conversions in dry-dock or in port or is laid up for a long period,
the master or the Administration may reduce the frequency of the transmission
LRIT information to one transmission every 24-hour period, or may
temporarily stop the transmission of such information.
12.2 Administrations should issue instructions
to masters of ships entitled to fly their flag in relation whether
they are authorized, and if so under what circumstances
and on how they are able, to reduce, pursuant to the provisions
of paragraph 4.4.1 of the Revised performance standards, the frequency
of the transmission LRIT information or to temporarily stop the
transmission of such information when a ship is undergoing repairs,
modifications or conversions in dry-dock or in port or is laid up
for a long period.
12.3 It should be noted that, depending on the
duration of the suspension of the transmission of LRIT information,
the apparent savings to be realized may be less than the
cost and charges incurred as a result of consequence in terms
of communication services.
12.4 It is highly advisable that, instead of suspending
the transmission of LRIT information, to reduce the transmission
rate to one every 24 hours and thus also leave the ship integrated
in the LRIT system.
