Commissioned by Spie Nederland, Marine Systems has realised three new salinity, temperature and pressure measuring points. The project was carried out in collaboration with Lomans Capelle and de Klerk Werkendam. Due to the construction of a salt extraction dam in the Binnenspuikanaal in IJmuiden, the water to be discharged will be saltier than before. The new situation has consequences for both the pumping station and the discharge lock. In order to gain more data and to be able to implement targeted improvements where necessary, the need arose to measure the salt content and the water pressure at three different depths. In collaboration, Marine Systems realized both the measuring construction and the collection of the data. The project approach was partly derived from the previously realized measuring setup on the Amsterdam Rhine Canal.
After a design and production phase, the curved tube construction was placed and secured on the bottom of the canal. The data collection station was then placed on shore and the three measuring pipes of the sensors come up through the bottom of the cabinet. The sensors were then mounted and connected. To ensure that the sensors are always replaced at the exact same spot and thus provide reliable data, a sturdy construction with a fixed stop (against which the sensor rests) has been fitted in the tube.
In the design and realization phase, extensive consideration was also given to the ease of maintenance of the sensor. For the purpose of maintenance, a method was developed with which the sensors can be maintained and replaced (if necessary) without the use of divers.
Because it was a large project with many stakeholders, good communication and coordination were of great importance. Prior to the activities any risks were identified and controlled with measures.
In addition, it has been made clear which interfaces there are with, among others, the users of the waterway, the builder of the salt extraction, traffic on the shore and the Spuisluis and the pumping station in general. Marine Systems was responsible for the overall project management.
