ABSTRACT
Germany’s waterway network spans 7,300 km with 3,000+ hydraulic structures, many in urgent need of repair. Years of underfunding have led to a significant maintenance backlog. The Federal Waterways and Shipping Administration (WSV) is shifting from reactive to preventive maintenance, focusing first on steel components. By estimating long-term needs based on the lifecycle of weirs and locks, WSV aims to increase annual maintenance rates, requiring more personnel and equipment. A collaborative project with a maintenance office is identifying necessary measures, intervals, and resource needs. Operations research methods optimize resource allocation, and results will be visualized for strategic decision-making.
