Underwater ROV and AUV engineering
Design and integration of underwater vehicles and instrumented subsea platforms — frame, pressure housings, propulsion, sealing and payload — for marine research groups, defence establishments and industrial users.
What we do
Whole-platform subsea engineering.
We work on underwater platforms as complete systems rather than as parts lists: frame and structural design, pressure vessel selection and sealing, thruster sizing and layout, cable routing and bulkhead entry, buoyancy and ballast budgeting, and integration of the sensor payload the vehicle exists to carry.
Being an authorised distributor for the Blu-Sub subsea range alongside the engineering work means specification and supply happen together. A depth rating, seal compound or gland size confirmed during design is the one that gets ordered, rather than being re-derived from a catalogue months later by someone who was not in the design conversation.
How we work
Depth rating is a system property.
The first thing we establish is the real operating envelope: depth, duration, water conditions, deployment method and recovery plan. Depth rating in particular is a property of the whole assembly — the shallowest component in the chain sets the vehicle's rating, however deep the others go.
Buoyancy is tracked from the first structural decision rather than calculated at the end. Frame, housings, thrusters, cabling and payload all contribute mass and displaced volume, and a platform designed without that running total is the one that arrives at trials nose-down or unable to hold depth.
Pressure testing is treated as a standing pre-deployment step, not a one-time qualification. Seals and penetrators are validated in isolation before they are committed to a full assembly, and the assembled housing is validated with its real cabling before it goes in the water.
What you get
Deliverables.
Depending on scope, that ranges from a specification and component set — depth-rated housings, penetrators, thrusters and buoyancy sized against your payload — through to an assembled and wet-tested platform with its documentation.
The design package covers frame and mechanical drawings, the electrical and control architecture, the cable and penetrator schedule with seal compounds identified, and the buoyancy and ballast calculation with the assumptions behind it written down so it can be recalculated when the payload changes.
Validation evidence comes with it: seal and penetrator pressure tests, an assembled housing test with real cabling, and functional checks of propulsion and instrumentation before the vehicle is handed over.
