22 manufacturers. One point of contact.
We work with specialist manufacturers in underwater robotics, sonar, cold-cure repair, ultrasonic inspection, surface preparation and onboard systems. Because our range spans several specialists in each field, we can match the right one to your job - including when the simpler option is enough.
Working directly with each manufacturer
The difference matters on the day something goes wrong. Here is what it means in practice.
Full manufacturer warranty
Equipment comes through the manufacturer's own supply chain, so the warranty is the manufacturer's own - not a reseller's promise standing in for one.
Genuine parts and consumables
Cutter sets, needles, seals, hoses, filters, thrusters and tethers come from the factory. No pattern parts quietly substituted into a quote.
A factory escalation path
When a question outruns us, we ask the engineers who built it - and you get the answer, rather than a support ticket that stalls.
One quote across all of them
An ROV, a needle scaler, an epoxy kit and an ultrasonic tester can go on one purchase order, one shipment, one set of paperwork.
Grouped by what they do, not by alphabet
Every card goes to that manufacturer's pages on this site - the products, the specifications and the applications - not out to their own website. Where a job could suit more than one of them, we will tell you which fits it best.
Blueye Robotics
Inspection-class ROVs built for professional survey
The X1, X3, X3 Ultra and X7 - compact, cabled inspection platforms with a payload rail, cloud reporting and a Python SDK for integrators.
QYSEA
FIFISH ROVs with omnidirectional manipulation
Six degrees of freedom and a robotic arm on a platform small enough for two crew to launch by hand - hull checks, net inspection and light intervention.
Blue Robotics
Open ROV platforms and the components to build your own
BlueROV2, the BlueBoat surface vessel, T200 and T500 thrusters, enclosures and sensors on the open BlueOS and ArduSub stack. The choice when you need to modify it.
SEAMOR Marine
Modular inspection ROVs for heavier duty
Reconfigurable frames that take extra sonar, sensors and manipulators - for operators who need one vehicle to cover several jobs.
CHASING
Compact ROVs at the accessible end of the range
Light, quick-to-deploy vehicles for a first look - a sensible entry point when a full inspection-class platform is more than the job needs.
Tethys Robotics
Search and recovery in zero visibility and current
Built for police divers, fire services and rescue teams - a vehicle designed to work in the river conditions where cameras stop being useful.
BeeX
Hovering autonomous underwater vehicles
An AUV that holds station like an ROV - close-range structural inspection with no tether and no support vessel holding position above it.
RTsys
Survey AUVs and underwater acoustic recorders
NemoSens and Comet AUVs, long-endurance acoustic recorders, and the SEMA acoustic range for mine countermeasures and naval training.
DWTEK
ROV systems available through our rental fleet
Part of the fleet you can hire rather than buy - useful for proving a method on a real job before committing the capital.
Cerulean Sonar
Sonar, altimeters and tracking for small platforms
A 34-product catalogue of imaging and scanning sonar, echosounders, altimeters and acoustic tracking sized for micro and inspection-class vehicles.
Hydromea
Wireless optical data links and compact autonomy
LUMA optical modems that move data through water without a tether, plus the EXRAY untethered vehicle for confined flooded spaces.
Dantech Group - UNIGRIP
Cold-cure epoxy composites for corrosion, erosion and cavitation
The UNIGRIP series: cartridge-applied coatings, metal fillers, putty sticks and pipe wraps that cure without heat. No mixing error, no waste, no pre-heating, and it bonds to GRE pipe. ABS Product Certificate held.
Seacoat Technology
Hull and niche-area coatings that resist fouling
Coating systems for hulls, sea chests, thrusters and niche areas - where most fouling starts and most fuel penalty is generated.
Coltraco Ultrasonics
Ultrasonic instruments for compliance testing
Liquid-level testing of suppression cylinders without removing them, hatch-cover tightness testing, and watertight-integrity survey. The instruments behind a lot of SOLAS paperwork.
Hertzinno
Acoustic imaging cameras that show a leak and cost it
The HA3 range makes compressed air, gas and vacuum leaks visible on screen, then puts a leak rate, an annual cost and a CO₂ figure against each one.
CSpect
Telescopic pole systems for inspection at height
The ALTUM range puts a camera or sensor on a structure without scaffolding, rope access or a confined-space entry permit. Built up from poles and modules.
Vesselity
Hull condition analytics - measure before you spend
Turns hull and propeller condition into a number, so cleaning and coating decisions are made on evidence rather than on the docking schedule.
Trelawny SPT
Needle scalers, deck scalers and surface strippers
Mechanical surface preparation with Vibro-Lo low-vibration handles - which is what keeps a crew member inside their daily hand-arm vibration limit. ATEX versions available.
Graco
Pumps, coating equipment and vapour abrasive blasting
Fluid transfer, cleaning and sanitising, lubrication, spray application, and EcoQuip vapour abrasive blasting for controlled surface preparation.
EVstinguish
Containment built for electric-vehicle battery fires
For car carriers and ferries, where the problem is not extinguishing the fire once but stopping it reigniting hours later in a full cargo deck.
JIMCO
UV-C and ozone treatment for cold stores and provision rooms
Compact air and surface cleaners that slow spoilage in provision rooms and cold stores - so stores last the voyage instead of the first leg.
What has to be true before we take a line on
Every line we carry is a judgement. These are ours, and they are the reason the list is 22 names rather than 200.
- It has to survive a working environment, not a datasheet Salt, vibration, temperature, cargo operations and crew who are busy. Equipment that only performs in ideal conditions creates more work for the customer than it saves.
- Spare parts and service have to be real We will not take on a line where a consumable is unobtainable in six months. Parts availability is checked before we take a line on, not after the first failure.
- The manufacturer has to answer engineering questions When a specification question outruns us, we need a route to the people who designed it. A brand that only offers a sales contact cannot be supported properly.
- It has to earn its place against what we already carry Overlap is deliberate, but only where the two genuinely suit different jobs. A second brand that simply duplicates the first makes our advice worse, not better.
- Documentation has to stand up to inspection Certificates, safety data sheets, class approvals and manuals in a form a superintendent or surveyor will accept. On the epoxy line, that includes an ABS Product Certificate.
The portfolio is only useful if we help you narrow it
Twenty-two manufacturers is a lot to compare. These tools search across the brands rather than pushing one - free, no sign-up, and each returns something you can put in a requisition.
ROV Finder
Depth, task, budget and portability in - a shortlist of matching platforms out, across every robotics brand we carry.
Match me to a system →Product Calculator
Four questions about the damage returns the right UNIGRIP product, the quantity, the film thickness and the prep tooling.
Size an epoxy repair →Tool Selector
Substrate, coating and access conditions in - the right surface-preparation tool and cutter set out.
Find the right tool →Part of Marine Holding
SepcoTech is one of three companies under Marine Holding. These are sister companies rather than manufacturers we distribute for - worth knowing, because it means there is more engineering behind an enquiry than our own headcount suggests.
SepcoTech A/S
Maritime repair, inspection, robotics and protection technology. Roskilde, Denmark - supplying worldwide.
