Mammoet float world’s largest lock doors around the globe

Mammoet float world’s largest lock doors around the globe

The three largest lock doors in the world were constructed for fitting at the new sea lock in IJmuiden, the Netherlands. Mammoet devised a series of unique solutions to transport the three lock doors and a 255 ton dry dock door from the South Korean construction site to the installation point at IJmuiden in the port of Amsterdam, the Netherlands. Each lock door weighs 3,000 tons and measures approximately 72 metres wide, 24 metres high and 11 metres thick.

Mammoet was involved from the beginning to design a safe and efficient transport and lifting process. Mammoet will install the doors at IJmuiden at the new sea lock, which will be completed at the beginning of January 2022.
