A new large sea lock is being constructed at the entrance of the North Sea Canal at IJmuiden that will provide access to the Amsterdam port region.
The new lock will be 500 metres long, 70 metres wide and 18 metres deep, making it the world’s largest sea lock. Construction began in January 2016 and the new lock will be available for shipping early 2022. From then on, Port of Amsterdam will be accessible 24 hours a day.

Drone films of the construction
In order to monitor the progress of the construction from the air, drone recordings are made every three months. In the drone film of the first three months of 2019, the following highlights are visible from the air: the walls under construction of the inner head (on the North Sea Canal side), the outer head (seaward side), the dividing wall, the western part of Middensluiseiland, the Lock Operation Centre (SOC), the construction of the lock sill cofferdam of the outer head (for opening and closing, the future outer gate will run across the lock sill), and the installation of anchors onto the lock chamber walls.
Reports on the construction of the New Sea Lock often use a number of technical terms, raising questions such as: What exactly is a sheet pile wall and what is a combi wall?
What is meant by the diaphragm method and the caisson method? What do these things look like?
We have listed the most used terms in a glossary with explanations and visual material.
Scheduled activities and obstructions
Some activities and obstructions have been scheduled in connection with the construction of the New Sea Lock. There are also scheduled activities and obstructions in connection with regular maintenance work to the North Lock and Middle Lock. An overview of the scheduled activities and obstructions of the North Lock and Middle Lock is given below.

When will the new sea lock be completed?
|1st half of 2016||Preparatory work including removal of the South Lock Island|
|Mid-2016||Re-routing of the inner approach channel to the Middle Lock & start of the construction of the new sea lock|
|2017||Contours of the new sea lock will become visible|
|Spring-2019||The gates of the new sea lock will be manoeuvred into place|
|2020-2021||Start testing of the new sea lock|
|Early 2022||The new sea lock will be put into operational service|
The completion of the new sea lock for shipping is scheduled for the early 2022. The first ships may probably start to pass through the new sea lock during the operational test phase.
Why a new sea lock?
- The North Lock will reach the end of its technical service life in 2029 and has become too small for today’s ever-larger seagoing vessels.
- The New Sea Lock is tide-independent and can be used 24/7.
- A new large sea lock allows new-generation larger vessels to pass through the North Sea Canal smoothly and safely.
- With a larger lock, the port has the possibility to grow from today’s 90 million tons to 125 million tons of goods handled per year.
