Kaliwaal 41 is one of just a few floating sand separation installations in the Netherlands and is currently playing an important role in the Dutch Maaspark Well River widening project.
The Dutch owner, Van Nieuwpoort Bouwgrondstoffen, placed the order for the works with Alewijnse last year and the project was performed in two phases; in mid-2020 and then early 2021.
The new Alewijnse control system is for the management of the updated technology on the Kaliwaal 41 which carries out the extraction, grading and delivery of sand and gravel in an efficient, productive, reliable and sustainable way.
In consultation with Alewijnse the project was well coordinated, enabling us to carry out the conversion in two phases during our downtime weeks. We are very pleased with the result. We are now able to monitor the operation and efficiency of our installation even better than before and Alewijnse can assist us remotely with their broad expertise.

Up-to-date and future-oriented
The result is an innovative and modern control system with lots of visualisation possibilities and assembled using the latest components available on the market today, which ensures that spare parts are readily available. In this way we create more operational reliability for the customer. In addition, the system is much easier to operate than its predecessor and provides clear insights for the user through, for example, targeted reports on faults, maintenance and running hours, registration and overload monitoring. This means the system offers many more options for monitoring downtime and planning maintenance.
For the upgrade, Alewijnse provided a comprehensive package of electrical and automation services, including the engineering, supply and installation of equipment and the project coordination and commissioning of the control systems. The visualization capabilities of the installation and the conversion from traditional hardware to a modern PLC/SCADA solution is now making a significant contribution to optimising the production processes and reducing downtime. The company has a strong focus on operational reliability and required the most up-to-date and modern system solution available for its installation.
In addition to the high quality of its equipment and its technical capabilities, Alewijnse was also a natural choice for carrying out the work, having undertaken the original design and installation when the vessel was built in 1998. The company has many years of experience with electrical and automation systems across a wide range of ships and industrial installations and this extensive experience and expertise was important for the successful completion of a project such as Kaliwaal 41 in a short time frame.
We were very pleased to receive the order from Van Nieuwpoort Group for the upgrade of the Kaliwaal. The cooperation with the client throughout the project was excellent. Together we were able to complete the project quickly, efficiently and satisfactorily. We aim to bring the same expertise in electrical engineering and automation to future projects and further cooperation.

Kaliwaal 41 is a unique floating pontoon equipped with an industrial installation that receives material extracted from the water bed, separates the sand from the gravel, and then uses screens to deliver up to 144 different grades of sand for industrial applications. It is one of just a few floating sand separation installations in the Netherlands and is currently playing an important role in the Dutch Maaspark Well River widening project, which aims to create a safe living environment in the Maas valley between Well and Aijen.
A custom sand dredger installation extracts the sand and pumps it to the Kaliwaal where it is separated on the basis of the particle size and then cleaned and dewatered. Thereafter different mixtures are prepared for different applications for concrete and construction companies.
Maaspark Well river
The Maaspark Well river widening project is an initiative of the Dutch municipality of Bergen (L) and an important link in the large national project 'Room for the River', which aims to give Dutch rivers more space to safely store excess floodwater for managed release. A member of the Kamperheul consortium, Van Nieuwpoort Group has deployed the Kaliwaal 41 to support the construction of a high water channel between Well and Aijen.
