Larger and wider ships
Ships have become bigger and wider in recent decades. Modern ships carry more goods and bulk. And there are also larger cruise ships. In order to continue to allow these ships safe and smooth access to the Port of Amsterdam at low tide, a larger sea lock had to be built at IJmuiden. In 2016, work therefore started on the lock complex. The new sea lock is scheduled to be taken into use in 2022.
Enormous lock complex
There are several locks at the lock complex. The Zuidersluis for pleasure craft, the Middensluis and the Noordersluis. Until now, the Noordersluis, built in 1929, was the largest. But this one no longer sufficed for economic but also technical reasons. What is going to happen with the Noordersluis in the future is still unknown. During the construction of the new sea lock, these three locks will remain in operation.
Selective extraction of salt water
There is also a pumping station complex on the north side of the locks. Here, salt water will be returned to the sea by means of selective extraction. This is necessary because otherwise the water in the hinterland would become too salty. Every time a ship passes through the locks, salt water enters the canal. Too much salt water in the North Sea Canal has a negative impact on our drinking water, nature and agriculture. A kind of screen has been built at the beginning of the Binnenspuikanaal. Salt water is heavier than fresh water. By keeping an opening at the bottom of the screen, most of the salt water disappears, leaving fresh water behind.
