Originally, 31 caissons were planned on the offshore dyke and 8 on the west crossing.
The setting-up of the caissons has been gradual.
On the West Crossing, the first three were placed on June 8. A total of 7 caissons were in place on June 18.
The 3 caissons adjacent to the "Centurion " battleship were placed on 9 and 10 June.
At the offshore dike, 12 caissons were placed for 11 June and 24 in total for 18 June.
