Replace Legacy Ship Communication Systems — Without New Hardware
TL;DR
Shipwize replaces legacy PBX, intercom, and cabin phone systems on vessels with a modern, mobile-first communication platform. Crew use their own smartphones — no new devices, no cable runs, no proprietary hardware. SIP integration preserves existing telephony.
The Problem with Legacy Ship Communication
Most vessels still rely on communication systems designed decades ago: fixed intercom terminals in cabins, proprietary PBX phone systems, and wired alert panels. These legacy systems share common problems:
- Hardware-bound: Fixed wall terminals limit crew to specific locations
- Expensive maintenance: Proprietary parts, specialised technicians, scheduled drydock work
- Vendor lock-in: Single-vendor ecosystems with expensive licensing and upgrades
- No messaging: Voice-only systems miss the efficiency of modern text communication
- No mobile access: Crew cannot receive alerts or messages away from their cabin
- No data trail: No searchable communication log for compliance or incident review
How to Replace a Shipboard PBX: Step by Step
- Assessment: Map existing PBX extensions, intercom zones, and SIP trunk configuration
- Shipwize deployment: Install Shipwize server(s) onboard, connect to vessel Wi-Fi
- SIP integration: Bridge existing PBX extensions to Shipwize via standard SIP protocol
- Crew onboarding: Crew opens PWA in browser — no download, no App Store, instant access
- Parallel operation: Run Shipwize alongside legacy systems during transition period
- Decommission: Phase out legacy terminals as crew adoption reaches coverage
What Stays, What Goes
| System | Replaced by Shipwize? | Notes |
|---|---|---|
| Cabin phones | Yes | SIP calls via crew smartphones |
| Intercom terminals | Yes | Push notifications + messaging |
| PBX server | Optional | Can integrate via SIP or fully replace |
| Bridge VHF / GMDSS | No | Regulatory requirement — stays |
| PA system | Complements | Shipwize adds targeted individual notifications |
Total Cost of Ownership: Legacy vs. Shipwize
Legacy PBX systems accumulate cost through hardware procurement, installation labour, annual maintenance contracts, and proprietary spare parts. Shipwize eliminates all hardware costs: the crew's existing smartphones become the communication devices.
- No new hardware procurement
- No cabin cabling or terminal installation
- No proprietary maintenance contracts
- Software-based — updates deployed remotely
- Scales to any fleet size without per-device licensing
FAQ
How do I replace a legacy intercom system on a ship?
Deploy Shipwize servers onboard, connect to the vessel's Wi-Fi network, and optionally bridge existing SIP extensions. Crew install the PWA on their smartphones. Run both systems in parallel during transition, then decommission legacy terminals.
Can Shipwize integrate with my existing PBX?
Yes. Shipwize connects via standard SIP protocol to any PBX system. Existing phone numbers and extension plans can be preserved.
What about areas with no Wi-Fi coverage onboard?
Shipwize requires onboard Wi-Fi coverage — the same infrastructure needed for any mobile solution. Most modern vessels already have crew Wi-Fi. Coverage can be extended with standard access points.
Is the legacy PBX replacement permanent?
It can be. Shipwize fully replaces cabin phones, intercom, and PBX functionality with mobile-first communication. However, many operators initially run parallel until full crew adoption is confirmed.
What is the ROI of replacing legacy ship communication?
Operators typically see ROI within 12–18 months through eliminated hardware maintenance, reduced technician visits, and avoided cabin terminal replacements. Operational improvements (faster incident response, better crew coordination) provide additional indirect value.
