Riverbed monitoring and surveying system

Regular inspection of the riverbed is important for the safety of navigation and for maintenance work on port infrastructure and marine areas. Specialized motor vessel equipped with modern computer systems, tools and instrumentation for monitoring and recording the condition of the riverbed, allows a specialized audits. Multibeam Echo-sounder, mounted on board provides a comprehensive picture of the depth, type of bottom sediments and the dynamics of the processes of distinct objects on the bottom and a number of other phenomena.


The boat was bought for the project "Establishment of River Information System in the Bulgarian part of the Danube - BULRIS" OP "Transport" 2007-2013 and is equipped with multi-beam echo sounder, which monitors and captures the profile of the riverbed. The vessel is equipped with specialized equipment for monitoring of the riverbed and will carry out audits in the Bulgarian section of the Danube. The motor boat "BULRIS" was built in the shipyard in Greece, is registered under Bulgarian legislation in the Executive Agency "Maritime Administration" under Bulgarian flag.

The vessel is equipped with the necessary navigation equipment for the implementation of the Danube River navigation (DGPS), AIS (Automatic Information System), a comprehensive interface integrated with radar, VHF radio with integrated ATIS decoder - stationary, with a frequency range corresponding to the Regional Agreement on radiotelephone service on inland waterways.

Captain of the ship: Pavel Kosov

Hydrography and other surveys
Teledyne PDS is a software package for hydrographic survey and dredging operations. It offers modules that cover the entire operation from acquisition to the end product. The software runs on standard PCs with Windows operating system. Teledyne PDS is available in different versions tailored to specific operations.
The purpose of the PDS software suite is real time reading of data from one or more sensors, make computations with the data, display the results of the computations and simultaneously log the data. To be able to control those processes a number of different views have been developed that will display the reading, computations, results, and logging processes. The data can be displayed either graphically or alphanumerically.
Data needs to be verified after the measurements and Teledyne PDS has several options to remove anomalies and outliers, either manually or automatically. The final presentation of the cleaned data can be in the form of models, tables, files, volumes, nautical charts and reports.
Teledyne PDS is used for many applications that involve measuring of the seafloor or riverbeds for hazardous areas, progress of the dredge and construction work and safe navigation. Quality control during data collection provides best quality data that makes processing even easier. Results are shown in the digital terrain model volumes calculation reports and charts.
