Sensors

Tower designs and manufactures a range of dredger, excavator, and crane sensors rated up to 30 metre water depth

Rated to IP68, made with environmental resistant protective housings, and proven very robust and reliable, surviving the most extreme conditions. They are used for the following applications
- Excavator boom, stick, and bucket angles.
- Cutter dredger arm angle.
- Trailer dredger arm angles.
- Crane boom angle.
- Pitch and Roll angles for all types of dredger.
Draft Sensors.
- Simple pressure sensors, modern, compact, and reliable, for use on all types of dredger.
Tide Gauges.
- Simple pressure sensors, with the addition of a power source, a control unit, and a radio telemetry system or an internet connection, for data output.
Winch Sensors.
- Used to measure the cable paid out, and can either be rotary encoders on the winch shaft, or static systems on the side of the winch drums.
Data Telemetry
- Data transmission by radio to other vessels e.g. other dredgers and dump barges, so all digging and dumping can be seen by everyone, and all vessel positions can be monitored.
Slew sensors.
- Attached to the turret of cranes or excavators, to measure the horizontal rotation angle.
Density and Velocity meters.
- Used to measure the density and speed of material being pumped from trailer and cutter dredgers.
Horizontal angle sensor
- For use on trailer dredgers to measure the lateral movement of the dredge arms.
Spud carriage sensor.
- For use on cutter dredgers to measure the fore and aft movement of the spud carriage.
Echo Sounder
- For use on vessels that are survey focused. Pressure sensor with all critical electronics contained within the housing. Select the depth rating that suits your operational depth to maintain the best possible accuracy.

Tower designs and supplies a range of equipment for wireless, radio telemetry, and internet connections.

Wireless links between on-board equipment and systems, including remote monitors.
Radio telemetry for linking to systems on other vessels, for GPS corrections, and tidal data.
Internet routers for remote access and support over the internet.

Tower Software Provides a complete Range of Hyrdographic Survey options including Single Beam, Multibeam, Side Scan and Backscatter.

High-resolution Mapping:
Multibeam surveys provide high-resolution bathymetric maps of the seafloor. The technology allows for the collection of detailed data points, resulting in accurate representations of underwater topography.
Efficiency:
Multibeam systems can cover a wide swath of the seafloor in a single pass, making surveys more efficient compared to traditional single-beam systems. This efficiency is especially crucial for large-scale mapping projects.
Improved Accuracy:
The use of multiple beams simultaneously enhances the accuracy of depth measurements. This helps in producing more reliable and precise bathymetric data, which is essential for various marine applications.
Data Density:
Multibeam surveys generate a dense point cloud of bathymetric data, providing a more comprehensive understanding of the underwater terrain. This increased data density is valuable for detailed analysis and interpretation.
Seafloor Characterization:
Multibeam sonar can be used to characterize the seafloor beyond simple depth measurements. It can provide information on the composition of the substrate, helping researchers and scientists understand the nature of the seafloor in terms of sediment type, geological features, and habitat.
3D Visualization:
Multibeam data can be used to create three-dimensional (3D) visualizations of the seafloor. This allows for a more intuitive interpretation of underwater landscapes and facilitates better communication of findings to a broader audience.
Safety in Navigation:
Accurate bathymetric data from multibeam surveys is crucial for safe navigation, particularly in areas with complex underwater topography. Nautical charts derived from multibeam data help mariners avoid potential hazards and navigate more safely.
Environmental Monitoring:
Multibeam surveys support environmental monitoring efforts by providing baseline data for assessing changes in the seafloor over time. This is particularly important for understanding the impact of natural events, human activities, and climate change on underwater ecosystems.
Scientific Research:
Multibeam surveys contribute significantly to scientific research in marine geology, biology, and oceanography. Researchers can use the collected data to study underwater geological processes, habitat distribution, and biodiversity.
Resource Exploration:
In addition to scientific research, multibeam surveys are essential for locating and assessing underwater resources such as minerals, oil, and gas. The detailed mapping of the seafloor aids in identifying potential resource-rich areas.
