A select few of our Subsea projects.

Submarine Hatch Opening

Marine Stainless Steel Housing, pressure compensated in a hostile pressurised saltwater environment. Custom housing saved significant space, maintenance schedules and complexity and increased reliability and performance.

Submersible Remote Operated Vehicles (ROVs)

On craft locking pins, tether release, power electronics, thruster positioning, manipulator arms, launch & recovery systems (LARS). Calibrated and tested to pressure requirements.

Subsea Valves

We have extensive experience in valve control applications. If you need customised actuators to operate in subsea conditions with pressure compensation then we can help.

Marine Power Generation

Wave, Tidal Power Generation, Turbine Control, Pump Hatch Control and many more applications. Operational in saltwater, in deep pressure and incredibly small packages. Reduce weight, space and complexity while simultaneously increasing reliability, performance and programmability.

Engine Control

World-class, competitive deep-sea drilling accuracy needs reliable, resilient actuators suitable for specialist marine applications to hold ships in position, often in demanding sea conditions.

Winch Brake

A braking mechanism for winch brakes for launching submersible ROV’s. This required back drive capability and a pressure compensated custom housing.

Pipe Crawler

Pipe cleaning robot. Required space-saving, reliable and highly accurate custom actuators. Supplied with an integrated motor.

Launch & Recovery Systems (LARS)

Bay door opening, winch assist or locking pins for submerged, semi submerged or harsh environment control systems. High reliability, high force, very low energy usage, maintenance schedules, weight and space requirements.

Submarine Door Dogs

100% Monel (non ferrous) actuator. Vacuum encapsulated feedback and motor components to meet military shock/vibration and salt fog requirements.

Personal Submarine

A novel project providing mechanical control to a personal submersible vehicle. Specification and design pf electro-mechanical controls involved in steering, diving & surfacing, launching controls and locking pins.

Marine Steering

Propeller pitch control, full ahead to full astern. Allows propeller to maintain speed while changing direction. Enables backing-up and moving ship forward to break up to 20 ft of ice.

Sonar Antennae Dispatch

A 100% Monel Actuator with vacuum encapsulated feedback and motor components. The design meets military shock/vibe and salt fog requirements and can operate for 90 days in seawater if pressure compensating oil fails. Also with corrosion proof TDC coating of internal components.
