摘要

Lock gates are key elements in a river transport system and unanticipated damage to them can have a high financial impact. The failure of even one gate can lead to losses of several million Euros [Eick et al, 2017; Treece, 2015]. There is thus a need for predictive maintenance before old gates reach the limit of their operating lives. But there are no standards or regulations for the monitoring of these structures, to enable damage to be identified in good time. In addition, access to lock gates is greatly constrained by navigation traffic and the continuity of service. Throughout the year, only a few interruptions to navigation traffic can be made, specifically for lock gate inspections and maintenance. The traditional way to manage this situation is to organize periodic onsite inspections of the structures. However, this can only provide for visual inspections of limited areas, sometimes using instrumentation, but often purely visual checks. Onsite inspections cannot access all parts of the structure, particularly the underwater areas of the structure where there are also potential areas of structural vulnerability. This means there is a limited time to detect defects and to provide an efficient action plan.To establish a predictive maintenance strategy, the use of monitoring solutions contributes to the provision of continuous and real time information, between navigation stops. The proposed approach aims at reducing the cost of the inspection and maintenance with a digital twin process to assist with remote control of the structure when it is needed, instead of prescriptive uninformed calendar-based inspections.
