ROV OVERVIEW

  • The open frame design allows easy access for servicing and maintenance as well as the easy addition of accessories such as cameras, sonars, navigation systems, manipulator, etc.
  • The vehicle has 4 vectored horizontal and 2 vertical thrusters and can move underwater in all directions.
  • The magnetically coupled propeller drive eliminates all rotating shaft seals for optimum reliability
  • The vehicle is operated from the surface control unit via a tether using joystick based on video and data from depth sensor on a TV screen.
  • Maximum operation depth is 500m and optionally can be upgraded up to 1000m
  • The ROV has one front full HD color camera with 180º tilt function, additional front or rear cameras can be installed on request, with maximum 4 extra SD cameras
  • Two powerful LEDs video lights are installed at both sides of the vehicle, each yield 7000 lumen.
  • Maximum power consumption is 6000 Watt.
  • The portable surface control system is integrated in waterproof case, which contains the power supply module, DVR and joystick.
  • The size of operating area is limited by cable length (max. 300m). It is possible to increase the cable length up to 1000m.
  • The video camera together with lights provides 15-20 m daylight visibility in the transparent water. Maximum 3-4 m visibility can be reached during the night.

 

Magnetic Propeller Coupling

With this design, a magnet array is fitted inside the hub of the propeller; and is driven by a magnet array attached to the motor inside the sealed pressure vessel. By eliminating the rotating drive shaft and shaft seals that always seem to leak over time, the technology achieves extremely high reliability. Additionally, the magnetic coupling will ratchet if overloaded, preventing damage caused by objects jammed in the propeller. And since the water lubricated propeller bearings are external to the pressure housing, they can be easily replaced in a matter of minutes.
