In order to ensure the availability of the maintenance requirements specified in SOLAS Reg. IV/15.7, combination of at least
two of the following methods should be taken as may be approved by the flag administrations, while taking into account the
recommendation specified in IMO A.702(17):
• duplication of equipment;
• shore-based maintenance; or
• at-sea electronic maintenance capability.
All ships irrespective of the methods used should make all manufacturers’ installation manuals and maintenance manuals
for all the equipment installed available. Adequate tools, spare parts and test equipment appropriate to the methods used
by the ship, as specified by the flag administration should be provided and readily available onboard.

VHF radiotelephone with built-in
DSC/DSC Watch Receiver
FM-8900S
MF/HF radiotelephone with
built-in

Carriage/functional requirements for GMDSS
Additional equipment to be installed on ships operating in the Sea Areas:
Maintenance requirement for ships operating in Sea Area and
Functional requirements to be fulfilled by FS-xx75* plus IB-585:
Other functional requirements:
◆ Distress and safety communications on all distress and safety frequencies
on MF and HF bands
•
using DSC
•
using radiotelephony
•
using direct printing telegraphy
◆ Continuous DSC watch on 2,187.5 kHz, 8,814.5 kHz, and on at least
one of the distress and safety frequencies:
4,207.5 kHz, 6,312 kHz, 12,577 kHz or 16,804.5 kHz
◆ Trasnsmission and reception of general radio communications using
radiotelephony or direct-printing telegraphy by MF/HF radio installation
1. VHF radio installation capable of
transmitting/receiving DSC on CH 70 as
well as radiotelephony on CH 6, 13 and
16 as well as contionuous DSC watch
on CH 70, and
An arrangement acceptable to
the flag administration should be
established to ensure adequate
support of the ship for the
maintenance and repair of the
radio installations, i.e., service
agreement with a capable service
provider covering the trading area
of the ship.
For ships operating in the sea area A4 only
occasionally but mostly operating in A3,
Inmarsat C MES may be installed for duplication in
lieu of MF/HF radiotelephone with built-in DSC plus
NBDP terminal, provided that the ship has originally
MF/HF radio installation.
Adequate additional technical documentations, tools, spare parts and test equipment
consistent with radio installation and as approved by the flag administration should be
provided onboard so that the maintainer can perform tests and localize and repair faults
in the radio equipment while at sea.
The person who is to conduct at-sea electronic maintenance should either hold an
appropriate certificate as specified by the Radio Regulations or have equivalent at-sea
electronic maintenance qualifications as may be approved by the flag administration,
taking into account the recommendation specified in Annex 5 of IMO A.703(17).
2. MF/HF radio installation for distress and
safety communications on the frequency
bands between 1,605 kHz and 4,000
kHz and between 4,000 kHz and 27,500
kHz, using DSC, radiotelephony and
direct-printing telegraphy. Continuous
DSC watch on 2,187.5 kHz, 8,814.5 kHz
and on at least one of the distress and
safety frequencies: 4,207.5 kHz, 6,312
kHz, 12,577 kHz or 16,804.5 kHz is also
required.
◆ Initiation of the transmission of ship-to-shore distress alert by radio services other than HF**
**Inmarsat C MES cannot satisfy the requirement, and this shall lead to the assumption that 406 MHz
Satellite EPIRB is the only option available to satisfy the functional requirement.
