IntelliWinch for sensors

IntelliWinch for sensors

The Intelliwinch is a highly flexible highspeed compact size instrumentation device for fully automated deployment of various sensors for the hydrographical and geophysical survey industry. The winch is delivered with software which enables operation with most common sensors, such as sound velocity meters, OBS, CTD, side-scan and magnetometer systems.

Today hydrographical and geophysical survey operation show an increasing demand for intensive probing of the water column and seabed with various sensors. Though manual operation is in most cases possible, it becomes less feasible. The rapid survey demand, cost for sea time and human factors generally favors an automated approach for most common sensors. Following this demand the design of the Intelliwinch not only focuses on the automated measuring cycle, but also on the integration of different sensors. Additionally the highly flexible system allows normal communication and operation with third party sensor and RheoTune software. Build in time series makes the device also very suitable for scheduled measurements from unmanned platforms.

KEY Features
– Time series with single probe sensors
– Automated correction for sensor height/ inclination /depth/multibeam depth
– Both for vertical deployment and towed devices
– Variable speed up to 90 m/min
– Safety settings for SOG, Slack wire, end-stop, water-depth, sensor tilt, depth
– Manual override for safety and quick profiling
– Frequency controlled engine enables smooth sensor movement

Typical applications
– Sound velocity profiling (continuous)
– Environmental sensors (OBS, CTD)
– Time series of scheduled measurements
– Side-scan sonar/magnetometer at constant depth above seafloor.
– Rheotune: vertical density/rheometry profiling

System description
The winch is operated by a dedicated software package: the Intelliwinch software. This software enables the selection of the sensor type and type of measurement (single deployment, fully automated time series, or constant height management for towed devices). The Intelliwinch control menu can be used to operate the winch. The main buttons are Up, down and stop. Also there is an option to enter the automated mode (for time series or tow-fish control). In this mode the software will control the winch depending on the sensor output. In the winch data display all relevant winch data can be observed, such as cable out, end stop, slack cable, and also all available probe data the system can use to control the winch. The single probe control settings and tow fish control settings enable user to make all settings for automated operation.
