The transition to Low Earth Orbit (LEO) satellite communications has transformed ship-to-shore connectivity. Deploying Starlink Maritime delivers broadband speeds exceeding 220 Mbps with sub-50 ms latency. However, achieving enterprise-grade maritime reliability requires rigorous RF mast design, multi-WAN bonding via Peplink SD-WAN routers, network segregation, and adherence to IMO MSC.428(98) Maritime Cyber Risk Management guidelines.

1. Starlink Maritime Hardware: Flat High Performance & Mast Placement
Unlike traditional stabilized VSAT parabolic dishes that rely on motorized mechanical gimbals, Starlink Maritime utilizes dual Flat High Performance phased-array antennas. With an electronic field-of-view of 140°, antenna placement on the ship’s monkey island or radar mast requires precise engineering:
Antenna Installation Engineering Guidelines:
- Radar Beam Clearance: Ensuring antennas are installed outside the main vertical beam lobe (±10°) of high-power X-Band and S-Band radar scanners to prevent LNA microwave burnout.
- Structural Wedge Mounts: Fabricating heavy-duty 8° stainless steel tilt wedges to shed rain and compensate for ship trim.
- Cable Penetration & Transit Frames: Routing ruggedized UV-stabilized Cat6A STP cables through Roxtec transit frames into bridge equipment racks.
- Power Supply & UPS Backup: Powering high-draw proprietary PoE injectors through dedicated online marine UPS units (230VAC / 24VDC).
2. Peplink SD-WAN SpeedFusion Bonding & Multi-WAN Failover
Standalone LEO terminals are susceptible to localized blockage from ship cranes or superstructure during vessel maneuvers. To achieve 99.99% uptime, Seanav engineers deploy enterprise Peplink Balance and MAX series multi-WAN routers:
- SpeedFusion Bandwidth Bonding: Combining dual Starlink terminals, coastal 5G/4G maritime SIMs, and legacy Inmarsat FleetBroadband or VSAT into a single bonded IP pipe.
- Hot Failover & WAN Smoothing: Zero packet loss failover for critical cloud telemetry, ECDIS ENC updates, and VoIP bridge calls without session dropouts.
- Dynamic Path Selection (DPS): Automatically routing high-priority corporate data over the fastest link while offloading bulk crew traffic to lower-cost paths.
3. Maritime Airtime Plans: Mobile Priority Data & Fleet Management
Seanav provides complete Maritime Airtime Account Opening, Monthly Maritime Airtime Contracts, and Maritime Airtime Billing Services. We manage Starlink Mobile Priority tiers (50GB, 1TB, 5TB, and pooled fleet subscriptions), delivering real-time bandwidth consumption analytics and remote terminal health telemetry.
4. IMO MSC.428(98) Cyber Risk & Vessel Network Segregation
Connecting a vessel to broadband internet exposes operational technology (OT) to cyber vulnerabilities. In strict compliance with IMO Resolution MSC.428(98) and IACS UR E26/E27, Seanav configures robust hardware network segregation:
| Network Domain (VLAN) | Connected Equipment | Security Architecture |
|---|---|---|
| VLAN 10: Critical Navigation / OT | ECDIS, VDR remote telemetry, Engine Alarm Monitoring | Strict stateful firewall rules; inbound WAN traffic blocked; outbound traffic limited to authenticated OEM VPN tunnels. |
| VLAN 20: Corporate Admin | Captain PC, Chief Engineer PC, Ship Management ERP | Encrypted corporate VPN tunneling, endpoint antivirus, and URL category filtering. |
| VLAN 30: Crew Welfare Wi-Fi | Crew smartphones, personal laptops, mess room Wi-Fi | Complete isolation from ship OT/IT; captive portal authentication; individual daily bandwidth quotas. |
5. Crew Internet Optimization, Captive Portals & Traffic Shaping
High crew data consumption can saturate satellite links if unmanaged. Seanav integrates Peplink captive portals with PIN-voucher systems, speed throttling per user, video-streaming compression, and automated peer-to-peer / torrent blocking to maintain predictable airtime expenses.
6. Turnkey Installation & Maintenance Across Indian Ports
Seanav delivers turnkey Maritime Starlink Installation and Configuration across all major Indian ports. Our team manages bracket fabrication, crane lift logistics, antenna alignment, network cabling, firewall configuration, and commissioning within a standard 12-to-24 hour port stay.
