This paper extends the 'go-with-the-flow' method to explore enclosed environments, like oil reservoirs, pipe lines that transport liquids, and industrial tanks for processing chemicals, where sensing nodes cannot establish communication with the external world. Nonetheless, large quantities of highly …

The harbors De Oude Haven and ‘T Sas fall dry during an extremely low tide. When these harbors fall dry, foundations will come in …

We report on a first field test in which miniaturized sensor motes were used to explore and inspect an operational pipeline by performing in situ measurements. The spherical sensor motes with a diameter of 39 mm were equipped with an inertial measurement unit (IMU) measuring 3-D acceleration, rotation, …

The local Dutch legislations (PGS-29) regarding the above-ground storage of flammable products have become stricter. This has led to the phasing out of Viking-Johnson couplings that are located inside of tank pits. These couplings are prone to leakage and they use rubber seals which are now prohibited …

When a pipeline is laid on the seabed it can be exposed to hazards of ship anchors, large fishing gear or ice keels. To prevent the pipeline of being damaged, the pipeline can be trenched. Trenching is a technique where the pipeline will be buried in the seabed to a certain depth. This can either be …

This report contains the results of the graduation research of Jurre Kuijper and Martin Volgers. The research goal is to find an appropriate model to calculate the heat transfer under different sets of system conditions. The system in this case is a sewer heat system, which consists of a sewage pipe …
