Notes
(1) LRIT guidance
· LRIT functionality via Inmarsat: Inm-C, mini-C or IsatM2M
· LRIT functionality in Sea Areas A1+A2+A3+A4 via Iridium
· A valid LRIT Conformance Test Report (CTR) to be available on board
Contact us for LRIT Testing
(2) SSAS can be met by satellite or terrestrial communication system
(3) Sea Areas A1+A2: LRIT arranged with Inmarsat-C or GMDSS mini-C is equivalent for duplicated MF SSB+DSC
(4) SBM of EPIRB required at every battery change or at least once every 5 years. Alternative method: Replace: the EPIRB with a new one VDR floating recording medium of new VDRs placed after 1 July 2014 includes EPIRB functionality and may fulfil the EPIRB requirement
(5) 2 pieces for passenger ships and cargo ships ≥ 500 gt and 1 piece for cargo ships < 500 gt
(6) At-Sea Maintenance as alternative for SBM is not in use
(7) Contact us for your annual Radio & AIS survey (Approved by the major Classification Societies)
(8) Contact us for all available service & maintenance agreements
(9) A) 2-way VHF radiotelephones, as follows:
· 3 pieces for passenger ships and cargo ships ≥ 500 gt
· 2 pieces for cargo ships < 500 gt
AND
B) Explosion proof or intrinsically safe 2-way portable radiotelephone
equipment: 2 pieces per fire party on board
· All ships built on or after 1 July 2014
· All ships built before 1 July 2014, not later than 1st survey after 1 July 2018
GMDSS is currently under review; first implementation of changes estimated in 2024
