Safety Warnings for Technical Status of Port Structure by Automatic Monitoring in Vietnam

The GNSS–RTK technique has been studied and applied to monitor the displacement of buildings in structural health monitoring systems (SHMs), especially with large-scale works such as super high-rises or bridges with long spans and special construction structures. Monitoring data obtained, including short-term and long-term (continuous), can be used to study, analyze the health status of the structure, detect damage, and predict future structural displacements. In port construction monitoring or maritime safety, the structural displacement or stability monitoring system has also been researched and initially applied by authors. However, the studies are still local, focusing on a few specific objects in a short observation period, not to mention the automatic warning of the risk level. In other words, people must also continuously monitor the data to detect risks when detected promptly. The article delves into the experiment of automatic safety warning monitoring of harbor works with whistles/lights or messages to solve the above problems. This is a new solution suitable for the 4.0 technology revolution era. Primarily, it is a valuable solution to monitor, evaluate/diagnose the stability of the port structure in case the construction is different from the design, in terms of operation and maintenance, to develop the port sustainably, safely, and effectively and minimize environmental impact.
