Subsea capability for navies, coast guards & first responders.
SepcoTech brings together the best of European and allied underwater technology — autonomous vehicles, diver systems, acoustic sensors and hull protection — into one defence portfolio, specified, integrated and supported from a single point of contact.
The threat picture below the surface has changed
Legacy ordnance, drifting and moored mines, threats to subsea cables and pipelines, and the constant need to know what is on a hull or a seabed — all demand answers that keep people out of harm's way and deliver a clear picture, fast. SepcoTech represents specialist manufacturers whose autonomous vehicles, diver-held systems and acoustic sensors are built for exactly that, and integrates them into mission-ready capability for naval, security and rescue services.
Start from the mission, not the catalogue
Buyers think in missions; suppliers are the implementation detail. Each mission below is scoped and delivered by SepcoTech as one cross-supplier package.
Mine Countermeasures & EOD
Search, detect, identify and dispose — robot first, diver last.
See the mission →
Coast Guard & Border
Faster hulls, cleaner searches, wider maritime coverage.
See the mission →
Police & Public Safety
Underwater search and recovery — with or without a diver.
See the mission →
Critical Infrastructure
Survey, inspect and defend the seabed estate.
See the mission →Eight specialists. One portfolio.
Each is a focused manufacturer in its field. Together they cover mine warfare, anti-submarine training, autonomous survey, wireless inspection, rapid situational awareness, rugged inspection & recovery, hull protection and ultrasonic readiness assurance.
RTsys
French underwater-acoustics specialist: a complete manned-and-unmanned mine counter-measures suite — diver sonar, MCM AUVs, acoustic firing — plus anti-submarine-warfare training targets and sonar measurement.

BeeX
Singapore robotics: hovering, untethered autonomous underwater vehicles for EMCON-safe seabed survey, MCM support and infrastructure inspection — with the Sambal cloud portal for fast reporting.
Explore BeeX →
Seacoat
Foul-release and protective coatings proven on military craft since 2001 — sustained speed, lower drag and fuel, fewer dry-dockings, and biosecurity control across steel and aluminium hulls.

Blueye
Norwegian portable underwater drones for navies, coast guards, police and rescue: a rapid first look under hulls, harbours and infrastructure, and a diver-safe option for search, recovery and forensics.

SEAMOR Marine
Canadian rugged, inspection-class ROVs already fielded by police underwater-recovery teams and port authorities: diver-safe hull and harbour search, search & recovery and forensic survey, scaling from a portable 300 m platform to a 1,000 m utility ROV.

Tethys Robotics
Swiss autonomous drone built for zero-visibility, strong-current and contaminated water — search & recovery, demining and UXO survey, security and police work where divers cannot operate.
Explore Tethys →
Hydromea
Swiss maker of ExRay — a wireless underwater inspection drone with a detachable optical flyout — plus LUMA light-based comms. Covert hull search for mines and contraband, confined-space inspection and protection of submerged critical infrastructure.
Explore Hydromea →
Coltraco Ultrasonics
British ultrasonic instruments that let a crew prove a warship is ready: watertight-integrity testing for damage control, fixed fire-suppression cylinder level and pressure checks, plus hull-thickness and flow measurement — non-invasive, single-operator, audit-ready.

One partner, from requirement to readiness
We are a distributor and integrator — not the manufacturer — so we stay platform-agnostic and assemble the right mix for the mission.
Define
We work from your mission, environment and constraints — not a catalogue — to scope the real requirement.
Integrate
We combine systems from across the portfolio into one coherent capability, quoted as a single package.
Deliver
Supply, acceptance and on-site familiarisation, coordinated through one point of contact.
Sustain
Training, spares and support through the full operational life of the system.
Defence-grade systems, shared with our marine-robotics fleet
Several of these platforms also serve commercial inspection and survey work. That dual-use base means proven, supported, in-production technology — and a deeper spares and training pool behind every defence delivery.
Built for the services that operate below the surface
From blue-water navies to municipal dive teams — scaled to the mission and the budget.
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.
Mission-First
Platform-agnostic. We scope from the requirement and integrate across suppliers, not from a single product line.
One Point of Contact
Multi-supplier defence systems, specified and quoted as a single package by one accountable partner.
Backed Through Life
Training, spares and support for the full operational life of every system we supply.
