Secure the seabed estate.
Survey, inspect, defend.
Cables, pipelines and offshore structures are now contested infrastructure. Protecting them means route survey, confined inspection, through-water data relay and structural condition monitoring. SepcoTech scopes that across suppliers and delivers it as one capability.
The infrastructure moved underwater. So did the risk.
Subsea cables and pipelines carry the data and energy that nations run on, and they are exposed. Protecting them is a survey-inspect-monitor problem across long routes, confined structures and poor visibility — no single platform covers it. SepcoTech specifies the mission and integrates survey AUVs, inspection ROVs, optical comms and structural inspection into one capability.
How a seabed-infrastructure mission runs
Each phase names the system that does it, and links to that system's page.
Cable & pipeline route survey
Survey AUVs run long, repeatable lines along cable and pipeline routes to establish a baseline and flag change — the first step in protecting a subsea asset.
SystemA.IKANBILIS / Survey AUV · BeeXConfined & tight-clearance inspection
A tetherless micro-ROV inspects tight clearances, J-tubes and structures where a tether would snag and a larger vehicle cannot reach.
SystemExRay · HydromeaThrough-water comms & data relay
Wireless optical modems move inspection data and commands through water at high rate with no acoustic signature — keeping robots connected in and around structures.
SystemLUMA optical comms · HydromeaStructure & anode condition
A hovering AUV fleet inspects jackets, anodes and structural members, building a repeatable condition record without divers or a large support vessel.
SystemHAUV fleet · BeeXWide-area acoustic search
Man-portable AUVs run acoustic survey to find objects on and around a route — from dropped anchors to hostile devices.
SystemAUV COMET-MCM · RTsysZero-visibility intervention
A zero-visibility, strong-current AUV inspects and intervenes close to structures where divers cannot safely or quickly work.
SystemTethys ONE · Tethys RoboticsThe systems, and where each one lives
The platforms that protect a subsea estate.
BeeX Survey & HAUV — Route & Structure
Hovering AUVs that survey long routes and inspect structures and anodes without a tether or dive team.

LUMA — Wireless Optical Data Relay
High-rate, no-acoustic-signature optical modems that keep robots connected in and around subsea structures.
Hydromea LUMA →
ExRay — Tight-Clearance Inspection
A tetherless micro-ROV for J-tubes, voids and tight clearances around infrastructure.
Hydromea ExRay →You cannot defend what you have never surveyed.
Protecting subsea cables, pipelines and structures starts with a baseline and a repeatable way to detect change. SepcoTech scopes the survey-inspect-monitor chain across suppliers and supports it as one.
How SepcoTech scopes and delivers this as one package
A seabed-infrastructure capability from SepcoTech is scoped once, across BeeX, Hydromea, RTsys and Tethys, and delivered as a single package — one specification, one quotation, one delivery schedule, one support contact. The interfaces between survey vehicle, optical comms and inspection ROV are our problem to solve, not yours.
What you get from one contract
- One requirement scoped across every supplier
- One specification and one quotation
- One delivery schedule and one warranty administrator
- One export-control conversation, not four (scope confirmed on enquiry)
- One training programme covering the whole toolset
Why it matters operationally
When a sensor and a vehicle from different makers have to work as one picture, a single accountable partner owns the integration — so the gaps between products are our problem, not yours. Platform-agnostic: we specify against your mission profile, not a single catalogue.
Who runs this mission
Navies & Seabed-Warfare Units
Baseline survey and change-detection along cables and pipelines in national and allied waters.
Energy & Cable Operators
Repeatable inspection of routes, structures and anodes to protect uptime and detect interference.
Ports & Harbour Authorities
Monitoring quays, intakes and approaches where a single failure or device disrupts traffic.
A safe pair of hands for defence at sea
Authorised Distributor
We represent each manufacturer directly — specification, supply and through-life support, coordinated from Denmark, inside NATO and the EU.
Scoped From the Requirement
Platform-agnostic. We specify against your mission profile and integrate across suppliers, rather than fitting your requirement to one product line.
One Contract, One Invoice
Multi-supplier systems specified, quoted and delivered as a single package by one accountable partner.
Backed Through Life
Operator and maintainer training, and through-life support for every system we supply; spares and calibration scoped on enquiry.
