Ship-to-Shore Communication Network
How a ship stays connected: satellite and 4G links, onboard networks separated for navigation, crew and operations, and the fleet operations centre ashore.
Drawing diagram…
What this diagram shows
- Navigation systems are on a separate, protected network
- 4G is used near the coast, satellite at sea
- The fleet centre monitors engines and fuel remotely
Prompt used
Ship network: the ship has a communications gateway that switches between satellite (VSAT or LEO) at sea and 4G near the coast. A firewall separates three onboard networks: bridge and navigation (ECDIS, radar), operations (engine monitoring, fuel sensors) and crew Wi-Fi. Operational data goes to the fleet operations centre ashore.

Port Community System
A port community system that connects shipping lines, terminals, customs, freight forwarders and truckers on one platform, so documents are shared once instead of emailed many times.
Import Container Clearance Sequence
The journey of an import container from unloading to leaving the port: discharge, customs filing, duty payment, delivery order and gate out.
Shipping Container States
The states a shipping container goes through in an export journey, from empty pick-up to delivery at the destination.
Vessel Tracking with AIS
How ships are tracked worldwide: AIS signals picked up by coastal stations and satellites, cleaned, matched to voyages and used for arrival predictions.
Container Terminal Operating System
Where a container terminal's systems run: the terminal operating system in the data centre, equipment control on cranes and yard vehicles, and gates with automation.
Ocean Freight Booking Schema
Tables for an ocean freight booking platform: shippers, bookings, containers, voyages, bills of lading and tracking events.
