      Tools for working at sea

      ROV
      Surveys, identification, inspection, sampling, recovery, filming
      Perfect to investigate Sonar or Sidescan findings

      Control from computer and ergonomic joysticks:

      Positioning system for underwater positions and allowing ship to follow ROV:

      System for navigating ship after ROV, using ROV and sensors:

      Gripper for recovery or release of objects:

      Max workdepth 400 meters
      Camera Full HD 1080x1920 with recording
      Manipulator/gripper
      Instruments: Scanning Sonar, INS, Accelerometers, Depthmeter, tempmeter, Laser Scaler
      Underwater positioning, SBL system to position the ROV within 1 meter:
      Get position of ROV, Move ROV to position, move ship after ROV

      Vectorized power; moves in all directions. Usage: Currents, rotation around object
      Thruster power 14 kg, Speed over 2 knots Weight 11 kg , Length 500mm
      Lights 2 x 1 500 lumens, with dimmer
      Control modes: manual, heading, depth, stabilized
      Electric power: 240 V AC from surface, or LiPo acc onboard

      Maneuvering ship following ROV gives possibilities
      Easy to survey long distances
      More precision in finding sites to investigate
      Ship handles most of surface currents, and less cable in water
      Possibility to hang equipment from ship

       

      Navigating in low visibility is not easy:

      Scanning sonar makes it easier to navigate:

      Texting on video, chosable after recording!

      Or use same video without texting:

      Laser Scaler to get size or distance:

       

      Mapping bottom cost effective:

      Basic example of mapping:
