Long Distance Remotely Operated Vehicle (LDROV)
SeaView System’s Long Distance Remotely Operated Vehicle is a custom ROV fitted with fiber optic telemetry system and custom power handling equipment. It is driven by four (4) 300W brushless DC thrusters (vector thruster configuration) giving a total forward thrust of 72 lbs. The ROV is built into a custom plastic frame fitted with freewheeling wheels on the top surface to provide smooth running along the crown of pipelines and tunnels.
For operations within the US and Canada the equipment is generally hauled to the inspection location in a small 10’ x 5’ covered trailer however the entire system is set up for air-freight as three packages with total weight of 2000lbs (900kgs).

- Recording
- All three video channels recorded independently to DVR
- Audio commentary recorded as required throughout
- Sonar/profiler data recorded continuously for report generation.
- Umbilical line counter recorded continuously for report generation
- Data Playback Options
- ODESSA MSX Video Viewer (allows for synchronous playback of up to 4 channels of video)
- 3rd Party Video Playback software once SeaView supplied CODEC is installed
- SeaView 3D PipeWalk software. In house developed software allowing user to virtually “walk” through 3D model of pipeline while viewing 3 channels of recorded video.
