Port lock renovation enables automation

Currently operated round-the-clock by onsite lock keepers, the lock will soon transition to remote operation following a comprehensive renovation led by infrastructure specialist Vialis.

This marks the start of a large-scale overhaul of the entire lock complex, including lock gates, bridges, control systems and support buildings.

“The mere fact that some 20,000 vessels pass through here every year demonstrates just how important the lock is for the port of Rotterdam,” said Berte Simons, chief operating officer of the Port of Rotterdam.

“Various parts of the lock are approaching the end of their technical service life, so renewal is necessary. Research shows that renovation is much more sustainable than constructing a new lock.”

This latest phase follows earlier upgrades completed in 2024, when the northern fender piles were modernised. In 2026, the lock will close for six months to allow key construction work.

Once completed in 2027, the Rozenburg Lock will be operated remotely by the Harbour Master’s Division from the Rotterdam Traffic Center, marking the end of onsite operations at the last remaining lock managed directly by the port authority.

“The renovation of the Rozenburg Lock is a great integrated project at a key junction for shipping and road traffic in the port of Rotterdam,” said Christiaan van Es, project manager at Vialis.

“For these users, reliable renovation planning is essential, with safety always being the top priority.”
