01
Zero new seabed hardware
We use fibre that is already in the water. This eliminates cable-laying vessels, underwater robotics and ongoing subsea maintenance. The marginal cost of coverage scales with the cable, not with the ocean floor.
Critical undersea infrastructure protection
Securing the world's
critical undersea infrastructure.
D-UV transforms existing subsea cable networks into continuous, real-time sensor arrays. We provide persistent underwater domain awareness and prevent physical damage to subsea data and power lines, without deploying new seabed hardware.
95%+
of all international data is carried by undersea fibre optic cables
$10T
in daily financial transactions is routed through submarine cables
1.5M
kilometres of cable on the ocean floor, connecting every inhabited continent
Over 95 percent of data, and $10 trillion in daily financial transactions, travels globally across 1.5 million kilometers of submarine cables.
The Center for Strategic and International Studies describes this infrastructure as the soft underbelly of the world economy.
The problem
The invisible vulnerability
Over 95% of global data traffic and a fast-growing share of power transmission run across the seabed. The infrastructure carrying them is blind to what happens around it until something breaks.
Modern maritime surveillance stops at the waterline. While surface vessels are tracked via radar and AIS, subsea data cables, power interconnectors and offshore wind export lines lie exposed to anchor dragging, fishing gear impacts and deliberate sabotage.
When a cable is cut, the operator finds out when the signal drops. Then come weeks of downtime, repair bills in the millions, and an argument about who pays.
No awareness
Damage is discovered after the fact, hours or days later, when data links fail. There is no real-time picture of the domain.
Deniable incidents
Anchor dragging and low-speed underwater activity produce no surface signature. They are invisible to radar.
No evidence, no deterrent
Without detection there is no record. Without a record there is neither liability attribution nor insurance recovery.
Our solution
Existing cables as an intelligent grid
D-UV delivers an integrated hardware and software edge platform that monitors subsea infrastructure from shore. By deploying intelligent signal processing at existing cable landing stations, our platform detects, classifies and pinpoints maritime activity along hundreds of kilometres of subsea cable route.
02
Early anchor and threat alarms
The platform identifies irregular vessel behaviour and dragging anchors in advance, transmitting precise coordinates to Vessel Traffic Services and vessel operators before physical contact occurs.
03
A record that holds up
Every incident leaves an immutable, time-stamped acoustic record. That gives cable owners and insurers something to put in front of a loss adjuster or a court.
Capability
From raw signal to operator decision
Operators need a prioritised picture they can act on, and a record that stands up afterwards. Three steps get them there.
Observe
The platform connects at the landing station and continuously measures the physical disturbances that vessels and underwater activity imprint along the cable route. Nothing new is placed on the seabed.
Orient and decide
Our classification layer reduces continuous raw measurement to meaningful events, separating routine traffic from behaviour that warrants attention, and delivering something an operator can read at a glance.
Act
Operators receive prioritised, actionable alerts with position. Full replay, audit trail and incident logs are retained under the operator's own governance for evidential and regulatory use.
Deployed where the cable already comes ashore
Because the platform attaches at existing shore infrastructure, a route can be brought under monitoring in weeks, with no seabed survey, no deployment vessel and no offshore maintenance programme.
Why D-UV
The cheapest coverage is cable that is already there
| Capability | D-UV | Surface buoys | Underwater drones | Military sonar |
|---|---|---|---|---|
| Uses existing infrastructure | ✓ | ✗ | ✗ | ✗ |
| No seabed hardware required | ✓ | ✗ | ✗ | ✗ |
| Continuous, autonomous coverage | ✓ | ~ | ✗ | ~ |
| No maintenance vessel | ✓ | ✗ | ✗ | ✗ |

| Deployable in weeks | ✓ | ✗ | ✗ | ✗ |
Coverage that scales with the cable
Because D-UV integrates with cables that already exist, there is no seabed survey, no deployment vessel and no ongoing offshore maintenance. Each additional kilometre of monitored route costs a fraction of what new seabed instrumentation would.
Speed of deployment
Surface buoys require anchor placement, surface hazard management and annual servicing. Underwater vehicles need pilots and charging infrastructure. D-UV attaches at a cable landing station and is operational in weeks.
Regulation
NIS2 and CER have ended passive infrastructure
With the European Union's NIS2 directive and the Critical Entities Resilience mandates in force, passive monitoring of subsea data and energy lines is no longer a choice. Infrastructure operators are legally obliged to maintain active, continuous risk supervision.
D-UV brings together Nordic engineering from NTNU and the verification standards defence customers ask for. Telecom operators, energy utilities and maritime authorities can meet the new obligations with something they can actually run and afford.
Who we build for
- Telecom and subsea cable operators
- Transmission system operators and energy utilities
- Offshore wind owners and export cable operators
- Ports, harbour authorities and Vessel Traffic Services
- National maritime authorities and defence customers
- Insurers and claims investigators
