Source Steering System

The Seismic Stuff Technology Source Steering System is designed to be able to steer the source sub arrays and/or to be able to collapse the bridle to facilitate source recovery.

The system works by driving winches placed on the sub arrays whilst keeping track of the position of the winch so they are not run beyond their physical limits.

The winches are air powered and can be driven in both directions, both hoist and slack. The system drives the winches by controlling two bolt gun solenoids to regulate the airflow to the winch. The two solenoids control the flow of high pressure air to the winch, energizing one solenoid will cause the winch to hoist, energizing the other will cause it to slack. Only one solenoid is operated at a time.

A rotation sensor is mounted on the winch housing which counts the number of times a magnet passes the sensor. The magnets are mounted on the end face of the winch drum. The sensor is capable of detecting if the magnet passes in a clockwise or anticlockwise direction hence the system is able to keep track of the amount the winch has deployed or recovered.

The system can be controlled directly from a rack mounted controller or via a web based interface from any PC with web browser on the same network. The web based access is password protected to stop unauthorised remote operation of the system.

An optional remote keypad is available which allows gun deck operation of the system whilst the operator is watching the winches.
