ABSTRACT
In the coming decades, the storm surge barriers in the Netherlands will reach their end of the designed life time of 100 years. Therefore, the Dutch storm surge barriers are preparing for major renovations. Next to this, as a result of the expected sea level rise, the hydraulic loads and the number of necessary closures will exceed the original design requirements. This gives urgency to look further than an one-to-one replacement or conservation and it a good moment to include changes in functional requirements. The functional end of life is, however, typically surrounded by large uncertainties. Since storm surge barriers bear multiple functions (e.g. hydraulic safety, the environment, shipping and road traffic infrastructure connection), changes in conditions can lead in several ways to the functional end of life. In this paper we explore what aspects should be added to current asset management strategy to include the functional performance of our hydraulic structures.
