FAIR Peer 2 Peer
In June, a first meeting was initiated by Rijkswaterstaat inviting the Landesbetrieb für Strassen, Brücken und Gewässer (LSBG). In preparation of this meeting participants were asked to send in three questions that they wanted to ask their partner during this peer-to-peer meeting. These 6 questions formed the basis of the program including a field visit (Strom Surge barrier Hollandse IJsselkering). The regional water authority Schieland and Krimpenerwaard was joining this peer2 peer as well as TUHH and IHE.
The result of this meeting was for example that we identified three areas we want to develop together:
- What are the best systems to maintain a common good level of information
- Documentation of technical objects to demonstrate compliance with national and EU regulations and guidelines
- How do you verify theoretical models for asset ageing/deterioration with historical data and actual measurement data?
We made a new appointment to deepen the understanding and applicability of the failure tree for a flood defense construction in Hamburg. This meeting was in September. The conducted assessment of the reliability of the Hamburg flood gates is based on a generic Rijkswaterstaat model. The test of the reliability of the closing process of movable structures such as flood gates are performed on the basis of score tables and standardized fault trees with four sub fault trees regarding failure in the storm surge alert, the mobilization, the operation and technical failure.
We found out that this type of assessment can give a good overview of the overall situation but does not serve as a detailed analysis. It can point out which of the four failures (alert, mobilization, operation and technics) is most likely to determine the overall failure probability of the timely closure. If a sharper estimation of failure probabilities for specific processes is wanted, a more advanced risk analysis method should be used.
In January 19th 2019 another Peer2Peer meeting is scheduled in Hamburg giving the Dutch colleagues the opportunity to get answers on their questions.
The overall feedback is that it is a good way to work together in small groups on a specific theme and have experts discuss their different approaches and enrich their knowledge.
Other suggestions for future Peer2Peer meetings are welcome, for example : duty to care approach, knowledge transfer and safeguard knowledge within institutions, flood protection during severe conditions (temporary barriers), etc.
