Inmarsat-C, FleetBroadband & SSAS / LRIT Conformance Survey & Battery Capacity Certification

In compliance with SOLAS Chapter IV (GMDSS), SOLAS Chapter V (Regulation 19-1: LRIT), and SOLAS Chapter XI-2 (Regulation 6: SSAS), shipboard satellite communication terminals must undergo periodic conformance testing, annual radio survey endorsements, and battery capacity verifications. These satellite systems provide non-duplicative global distress alerting, secure maritime security messaging, and continuous flag administration tracking.

1. Regulatory Framework: SOLAS Chapters IV, V & XI-2 Mandates

Satellite communication forms the backbone of ship safety communications in Sea Areas A3 and A4. Under International Maritime Organization mandates, Inmarsat-C terminals provide dual functions: standard commercial store-and-forward telex/email messaging and life-critical GMDSS distress alerting via dedicated distress push-buttons. Seanav delivers certified Inmarsat-C Supply, Inmarsat-C Installation, SSAS Supply, and LRIT Conformance Testing across Sailor / Cobham (TT-3000 / TT-6110), Furuno (Felcom 18 / Felcom 19), and JRC (JUE-87) suites.

2. Inmarsat-C Performance Verification (PV) Tests & Antenna Domes

During the annual safety radio survey, our radio engineers verify the link integrity of the Inmarsat-C installation:

3. Ship Security Alert System (SSAS) Covert Buttons & Test Routines

SOLAS XI-2/6 requires an approved security alert system capable of initiating a covert transmission to competent authorities (Flag State and Company Security Officer) in the event of a pirate boarding or hostile takeover, without raising an alarm on the ship:

• Covert Activation Buttons: Testing at least two hidden panic buttons (one on the navigation bridge and at least one other remote location, such as Master cabin or engine room control room).
• Dedicated Covert Test Mode: Ensuring that tests are transmitted using specific TEST message tags to prevent triggering armed naval coast guard responses.
• Power Supply Isolation: Confirming that the SSAS unit operates on uninterrupted emergency battery power and cannot be silenced from bridge consoles once activated.

4. LRIT Conformance Testing & Conformance Test Report (CTR) Issuance

SOLAS Chapter V Regulation 19-1 requires commercial vessels to automatically transmit their position, course, and speed to the national LRIT Data Centre at 6-hour intervals (or polled on-demand down to 15-minute intervals). Seanav coordinates official LRIT Conformance Testing through authorized Application Service Providers (ASP), including Pole Star, Fulcrum Maritime, and Transas, issuing the statutory Conformance Test Report (CTR) required by Flag State administrations.

5. FleetBroadband Terminals: Voice, High-Speed IP & Emergency Fallback

FleetBroadband (FB150, FB250, FB500) terminals provide continuous satellite voice communications, background IP internet, and emergency 505 safety calling. Our technicians inspect 3-axis gyro-stabilized antenna tracking pedestals, update modem firmware, and calibrate RF power outputs.

6. Statutory Class Certification & SBM Services Across UAE Ports

Seanav provides complete Shore-Based Maintenance (SBM) certification, Inmarsat terminal repairs, and radio surveys across all major UAE ports, including Kandla, Mundra, Mumbai, JNPT, Cochin, Tuticorin, Chennai, and Visakhapatnam.
