Electric tether management system E-TMS

Test phase initiated

​Our brand new fully electric TMS "octopus"are now being tested in our facility, this TMS are new in the marked.

Technical features:
  • Main frame constructed in steel or aluminum (selectable), frame can be constructed in parts that again will enable single part replacement in case of damage.
  • 4000m depth rating
  • Up to 1500 meters tether
  • Weight 2400 Kg exclusive tether/bullet
  • Variable tether speed of 0-60m/min
  • 5000N adjustable pull force
  • ROV capacity 5000Kg
  • 2 cameras and LED light fixtures included, spare ports available
  • VFD controlled motors have position feedback in addition to full control of tension/torque
Optional equipment:
  • Cover doors
  • Control system
  • Tether
  • Swivel
  • Bullet/swivel landing arrangement
  • ROV toolbox
  • Additional camera/light fixtures
  • Gyro

​Key benefits of this E-TMS:
  • Full tension/torque control
    • Max pull force between the drum and spooling unit is adjustable by the operator during flight, hence the main pull force on the tether is in the entry spooling unit, lower spooling unit have a better radius/force impact on the tether.
    • Separate control for drum, spooling and winder functions
    • Automatic release/lock of winder function in high torque/locked drive screw situation
    • Constant tension control between E-TMS and ROV, this parameter is changeable during flight; this feature will also extend the lifetime of the tether.
  • Automatic docking/undocking function included fail-safe locking
  • All parameters in the control of forces and functions can be changed "in-flight"
  • All electric functions, no hydraulics actuators/motors
  • Repeatability
  • Environmental (no hydraulic oil in the unit)
