The article, “Cloud-based system for monitoring loads generated on the quay wall by ship propeller jets,” introduces a system for monitoring loads generated on the quay wall by ships during berthing and unberthing maneuvers.

The presented system was designed on the basis of previous studies on the loads induced by propeller and rudder thrusters of ships. A prototype of the system has been installed at the Port of Gdynia and has been in operation in its current design since 2020.

The system has a modular structure consisting of a network of pressure sensors, information mapping server, communication module and web server and its open architecture allows for further development and integration with external systems. It offers real-time monitoring of berthing and unberthing maneuvers and logging them in a database, as well as receiving information on exceedances, which may result in quay damages.

Damage to seabed protection has been significantly reduced since the monitoring system was implemented. During the last three months of the monitoring period, when all ship captains were informed that the monitoring system was in operation, the permissible pressure was exceeded only a few times, causing no damage to seabed protection.
