DCN Diving was contracted by Artes Roegiers in 2018 for the design and fabrication of a purpose-built cofferdam in order to rehabilitate the quay wall of the cruise terminal in Antwerp.
The Cofferdam consisted of 7 sections, when assembled 14.5 meter heigh and 5 meter wide. When the Cofferdam is installed dewatering takes place. Once this is completed the area of repair is cleaned with HP Waterjet. Once this area is clean, formwork is installed with reinforcement after which concreting takes place.
There are several positions on the quay wall which requires repair, the cofferdam is therefore installed on several positions and activities are repeated.
