The Stevin sluice complex is over 90 years old. In order to ensure that the navigation lock can continue to operate, the concrete structure must be inspected and any identified damage must be repaired. This ensures that the structure remains safe in the future.
We will first drain and clean the navigation lock. We will then inspect it for damage and repair any minor damage immediately. It is currently not yet clear how extensive this work will be. We can only inspect the navigation lock for damage once it has been drained and cleaned.
The concrete inspection and repair work will take approximately 10 weeks and will take place during the shutdown of the Stevin locks from October 2020 to April 2021. This shutdown is due to the construction of a new storm surge barrier in the lock approach of the lock complex. Ships must use the Lorentz locks at Kornwerderzand.
The Lorentz locks in Kornwerderzand will be inspected later. The inspections and any repair work will be part of the project for expanding the navigation locks. It is currently not yet clear when this project and the inspections will take place.
