New lock improves accessibility of Amsterdam for the latest generation of ocean-going vessels

IJmuiden - After almost 100 years, the Noordersluis in IJmuiden is due for modernization. A new, larger sea lock will improve the accessibility of the Port of Amsterdam and stimulate the economy in the region.

meter long (cruise) ships

This new tide-independent sea lock will be 70 meters wide, 500 meters long and 18 meters deep. With this length and width, the new sea lock will soon be the largest sea lock in the world. Construction started at the beginning of 2016, and the new sea lock will be opened to shipping at the end of 2019.

The Dutch Ministry of Infrastructure and Water Management (Rijkswaterstaat) awarded the contract for the construction of the new IJmuiden sea lock at the entrance to the North Sea Canal to the OpenIJ consortium. This consortium, consisting of BAM-PGGM, VolkerWessels and DIF, is responsible for the design, construction, financing and 26-year maintenance of the new sea lock.

Arcadis is also involved in the design of the lock, providing nautical and hydrological advice. We have carried out computational fluid dynamics (CFD) computations for instance to calculate the currents in front of the lock doors.

SHIP Navigator

For the construction phase of the new sea lock and for the final situation, the safe entry and exit at the nearby Noordersluis was investigated using the ‘SHIP Navigator’ ship simulation package. Arcadis analyzed the possible nautical risks together with the parties involved. Real-time maneuvering simulations were then carried out in the presence of the pilotage services that provided information on the maneuvering strategy and tugboat assistance. The simulation provides insight into the maneuvering procedures, limiting conditions, nautical risks and possible mitigating measures, thereby ensuring safety and efficiency during the construction and in the final situation.

Lock program

The new sea lock forms part of the Ministry of Infrastructure and Water Management's lock program in which various lock projects exchange know-how and experience. Arcadis is also involved in the design of the new lock in Terneuzen.

Partnership

The project is a joint venture between the Ministry of Infrastructure and Water Management, the province of Noord-Holland, the Municipality of Amsterdam, Havenbedrijf Amsterdam NV and the Municipality of Velsen. The project is partly financed by the European Union’s CEF (formerly TEN-T) program.
