SeaWay Dome
Wide-area underwater security and defence
SeaWay Dome gives sovereign and infrastructure customers persistent underwater presence across ports, cable landing zones, offshore energy areas, island routes, strategic corridors and territorial waters.
SeaWay Dome uses installed seabed devices, AUV patrols and secure information recovery to monitor, inspect and support authorised response below the surface.
Installed devices can carry mission-specific payloads, including asset integrity, passive acoustic, ADCP / current, water environment, temperature, pressure, conductivity and magnetic interaction functions where configured. They hold local records, support INS correction and allow AUVs to recover information during patrol.
Industrial customers can start with asset integrity, environmental monitoring and security around defined infrastructure. Defence customers can scale the same architecture into territorial-water surveillance, deterrence, interdiction support and sovereign underwater defence.

Sensor payloads
Asset integrity, passive acoustic, ADCP / current, water environment, temperature, pressure, conductivity and magnetic interaction functions where configured
Applications
Subsea power and data cables, interconnectors, ports, harbour approaches, offshore energy areas, pipelines, island routes, naval approaches, strategic corridors and territorial waters.
SeaWay Dome
Wide-area underwater security, critical underwater infrastructure protection and territorial-water defence
THE OPERATING PROBLEM
Periodic vessel, ROV and survey campaigns cannot provide persistent underwater access across critical infrastructure and territorial waters.
WHAT SEAWAY DOME DOES
SeaWay Dome uses installed seabed devices, AUV patrols, secure information recovery and operator-controlled tasking to create persistent underwater presence.
It supports operations across ports, cable landing zones, offshore energy areas, island routes, strategic corridors, naval approaches and territorial waters..
Start with monitoring. Extend to security. Scale to territorial-water defence.
CRITICAL INFRASTRUCTURE MONITORING
Monitor subsea power and data cables, interconnectors, pipelines, ports and offshore energy infrastructure. Configured devices can record asset integrity, seabed change, local environmental conditions and third-party activity.
SECURITY SURVEILLANCE AND INSPECTION
Authorised AUVs return to known locations, use INS correction, recover local records and inspect areas of concern. Repeat patrols create comparable evidence for security review and follow-up action.
TERRITORIAL-WATER DEFENCE
Extend the same architecture across harbour approaches, island routes, naval approaches, strategic corridors and wider sea areas. Support surveillance, deterrence, interdiction support and authorised response under sovereign command.
Installed seabed devices > AUV patrol and INS correction > Secure information recovery > Operator tasking and authorised response
Operating architecture, configured payloads and customer outputs
1. SENSE AND RECORD
Installed devices capture local conditions and hold time-stamped records.
2. PATROL AND CORRECT INS
Authorised AUVs return to known locations and improve repeatability.
3. RECOVER AND INSPECT
Recover selected information and inspect areas of concern.
4. OFFLOAD AND REPORT
Return through a dock, gateway, vessel or shore interface.
5. DECIDE, TASK AND RESPOND
Monitor, investigate, repair, escalate or support authorised response.
CONFIGURED PAYLOADS
- Asset integrity: fatigue, movement, free spans, scour, burial change and repair condition.
- Passive acoustic and ADCP / current monitoring where configured.
- Water environment, temperature, pressure and conductivity.
- Magnetic interaction functions supporting AUV access and information recovery.
DEPLOYMENT AREAS
- Subsea power and data cables, interconnectors and cable landing zones.
- Ports, harbour approaches, subsea utilities and exclusion areas.
- Offshore energy areas, pipelines and strategic seabed corridors.
- Island routes, naval approaches and territorial waters.
CUSTOMER OUTPUTS
- Surveillance records and repeat inspection records.
- Seabed change reports and security alerts.
- Patrol tasking and escalation evidence.
- Asset integrity, environmental and operating reports supporting follow-up action.
OPTIONAL FIBRE ADJUNCT
DTS can provide thermal and burial-related information. DAS can provide route-wide disturbance screening and help direct an AUV to the relevant area. Installed seabed devices retain local records and support repeat access.
THROUGH-LIFE SERVICE:
Initial deployment, AUV integration and commissioning are followed by recurring patrol, secure information recovery, reporting, maintenance, upgrades and support.
