Commercial Fishery Department conducted research into the hydrodynamics of the ‘vessel-trawl’ system

The Commercial Fishery Department conducted research into the hydrodynamics of the vessel-trawl system in the reverse-flow water channel at OOO Fishering Service. The experiment was supervised by A.A. Nedostup, Vice-Rector for Industry-Based Scientific and Methodological Activities. Young researchers from the department, postgraduates and students from KSTU actively participated in the research.

During the experiments, researchers tested the autonomous movement of an unmanned commercial catamaran, including the deployment and retrieval of the trawl. A strain-gauge station was used to measure the forces acting on the trawl sheaves. Remote control of the fishing catamaran and the wire winches enabled sea trials of the fishing catamaran and the main elements of trawling to be carried out: setting the trawl, reaching the specified depth and retrieval of trawl warps. Experiments in the hydrodynamic channel demonstrated the operational capability of the developed vessel-trawl system, enabling the next stage of work to be carried out on open water.

The research is being conducted as part of the state-funded project Development of a Wireless System for Monitoring Trawl Parameters with Artificial Intelligence Elements: Autotrawl.

The Commercial Fishery Department at KSTU would like to thank A.N. Fedorov, Director of OOO Fishering Service, for providing the opportunity to conduct experimental research in the hydro channel.
