Gas lines, district heating, water pipes, oil pipes, press sewers, underground power lines – they all run the risk of being damaged by ground subsidence. TNO maps these quality of underground pipes for asset managers with the help of sensors and simulation models.
Asset Managers are looking for cost effective and efficient ways to replace underground lines. At this moment it is done on the basis of substitution plans, which are based on data such as age, material type, thickness, location and density of the pipes. Often the maintenance or replacement can be delayed. Through the visual demonstration in practice, asset managers can better assess the quality or degradation rate of the network.
Within the project ‘Sensor Applied on Underground Pipeline Infrastructure’ (STOOP). TNO is makes the sensor technique of the IJkdijk applicable for different types of pipes. It started with the initiative of Liander, who wishes to forestall breaking of the underground pipes in the future such as it had happened in Amsterdam. The sector-linking research on the influence of Dutch land settlement on the underground infrastructure is a successful example of cross-sectoral knowledge development and exchange.

STOOP is an acronym for ‘Sensor Technologie Toegepast op Ondergrondse Pijpleidingen’ and can be translated as ‘Sensor Technology Applied to Subsurface Pipeline Infrastructures’.
