After six weeks of preparation, Jan De Nul Group's lifting vessel 'Gulliver' removed the gate on 21 May 2020 and took it to the inner port for the overhaul.
That was a spectacular operation because a gate of this kind weighs more than 2,500 tonnes and it is as large as a quarter of a football pitch (60 m x 10 m x 24 m).
For the replacement of the various steel structural elements in the gate, De Boer Snijbedrijf cut 36 tonnes of sheet steel S355J2 N to size and delivered it to Almex Metaal. Almex Metaal is welding the cut steel plates to the right places in the gate.
