Depth rated
Oil-filled construction and external compensation provide pressure equalisation across the full depth range.
Engineering
Built to keep subsea systems operational.
Every design decision in the SPT series is driven by a practical subsea priority: fewer failure points, less downtime and more predictable movement under load.
At a glance
The numbers that matter offshore.
Absolute position
The unit knows its position immediately on power-up, without a homing routine.
Low backlash
Precision strain wave gears support repeatable movement for inspection and intervention tasks.
Design philosophy
Reliability before everything else.
Subsea operations often run around the clock. Component failure means suspended work, vessel time and expensive recovery. Actuade designs for real offshore constraints and long service intervals.
The SPT series combines internal cable routing, high-mounted rotation, oil-filled gearboxes and configurable communication interfaces in a compact mechanical package.
Design features
Nine decisions that matter in the field.
6000 m rated
Pressure equalised design keeps operation predictable from shallow water to deepwater deployments.
High-mounted rotation
The rotation axis helps distribute impact loads away from the gear train.
Absolute feedback
12-bit absolute encoders report position at all times with approximately 0.1 degree resolution.
No rotating contacts
Internal cable routing removes a common electrical failure point from the rotating assembly.
Strain wave gears
Low backlash supports precise camera, sonar and instrument positioning under load.
Oil-filled gearboxes
Oil-flooded gear chambers provide lubrication and pressure compensation support.
Material options
Hard anodized aluminium as standard, with titanium available for applications with demanding corrosion requirements.
Connector choice
Customer-selectable connector options help match existing vehicle, skid and instrument architecture.
Ethernet / Modbus UDP
Ethernet with Modbus UDP support sits alongside RS-485 and RS-232 for modern subsea control systems.
Operator-led development
Designed with the people who recover the equipment.
Actuade products were developed in close cooperation with subsea operators, integrators and field technicians. The result is equipment that prioritises structural integrity, integration flexibility and uptime.
