ROV Pollux III - observation class ROV

The ROV Pollux III is an observation class ROV with an HD polyethylene frame, equipped with 4 electrical motors and with the following specifications:

The main ROV camera is fitted within the POD and it is installed on a dedicated support that enables a tilt angle up to 160°. The ROV system can bring to the surface 2 video signal at the same time, chosen from a maximum of 4 sources. Thus it is possible to install additional cameras and camcorders devices.

Further to the standard video equipment, the ROV Pollux III, can be outfitted with a wide range of accessories to satisfy client requirements.
Some examples of accessories include: manipulator, sonar, HD camcorders, wall thickness gauge, CP probe and pipe tracker.

The onboard software includes the following functions and capabilities:

  • auto-heading and auto-depth
  • compass and depth sensor calibration
  • video equalization
  • On Screen Display
  • clock
  • data export through RS232 and USB interfaces (the exported data varies based on customer requests)

OSD provides the following information:

  • compass reading
  • depth
  • auto-depth e auto-heading status
  • umbilical turn counter
  • time and data
  • free text (at the operator disposal)
