Construction of floating cellular box caissons
Sliding
form slowly rising,
creates first 10 cm of 12 m high caisson wall
Reinforcement is added, following
each step
of the form's rising movement
As the form rises, the base of the
platform
lowers, partially submerging the caisson
and relieving the platform of its weight.

afloat,
with its front side holes sealed. Water is
sipping in from the lower left hole.
With the construction platform
fully lowered, and
the front side holes sealed, the floating caisson is
now ready to be hauled out and launched in position
Tug boat pulling on ready to be
launched caisson.
Scheduled for later launch, two more caissons are
temporarily moored in the inside of the quaywall.
Controlled flooding of caisson's
four corner cells by
means of underwater pumps.

in place. The front
openings ("holes") are designed for wave absorption
and reduction of the reflection of waves after hitting
the quaywall.
