A lightweight CORAL AT ROV design is based on experience and developments achieved during successful CORAL ROV research and development project. The CORAL AT ROV system is an example of a system which incorporates latest and the most effective developments in the ROV technology.

Those include:

  • fiber optic data transmission
  • miniature high sensitivity S-VHS u/w TV camera
  • powerful brushless permanent magnets DC thrusters
  • reliable GESPAC computer system
  • composite frame and pressure vessels

Modular design and open architecture allows customer tailored modification to cope with different operational needs. Scientific and light work manipulative tasks could be performed using different tools and sensors. Three different thruster configurations are available. Due to an open frame design of the CORAL AT ROV the system could easily be equipped with standard ROV tools. Their integration with the ROV system is fast due to application of a flexible and easily programmable computer control system.

The list of optional equipment could include:

  • ROV manipulator
  • Pan TV camera unit
  • still camera c/w strobe
  • ROV omnidierctional sonar - TRITECH ST 325, ST 525 or 725
  • Hydroacoustic profiler - TRITECH ST 1000
  • Precision echosounder - TRITECH ST 150 or ST 975
  • Surface control unit - TRITECH SCU 3
  • Ultrasonic thickness meter
  • Corrosion potential meter
  • U/W navigation system transponder
  • Side scan sonar
  • Doppler velocity meter
  • Sea environment monitoring sensor (hydrocarbons, nutrients etc.)


In case of all questions regarding integration of a customer specified ROV's equipment contact manufacturer.


The standard CORAL AT400 ROV system consists of:

  • CORAL AT vehicle
  • Neutrally buoyant umbilical and storage real
  • Control console
  • Cable winch with heavy umbilical, launching crane - Option
  • TMS garage with underwater winch system - Option
