RheoTune: rheometric profiler by yield strength, viscosity to measure the nautical depth.

The RheoTune is a versatile system that provides both density and yield stress profiles of fluid mud simultaneously to determine the nautical depth. The fact that the RheoTune is pre-calibrated makes it easy and quick to deploy, enabling swift and accurate data acquisition. The RheoTune is a versatile system to be operated from the smallest vessel or stationary installation. To increase productivity further an automated electrical winch or manual lightweight winch with slip ring is available.

Designed to deliver density as well as yield stress profiles and running proprietary software for both acquisition and processing, results in a detailed almost real time display of the profile. The data that can be imported into sub–bottom profiling processing suites enabling a full and comprehensive picture of the fluid mud and its characteristics. The system has been proposed to be nominated as a standard for determination of the Nautical Depth in Chinese and Dutch ports. The system has been successfully applied during the maintenance of the Prorva channel, north Caspian Sea.

Areas of application:

• Assurance of the nautical depth (accessibility) of your harbour.
• Water bottom stability assessment in coastal studies.
• Managing dredging resources and disposal area’s.
• Monitoring of siltation quantities.

The collected data of the Rheotune survey with be processed on site by European geophysical specialists or in the processing center of the manufacturer in the Netherlands.
