Abstract (en)
[origin: WO2021219970A1] A cofferdam (110) is guided and installed against a submerged wall (2) of a structure (1) by one or more flexible lines (50). Each line is retracted, via an opening (7) formed in the wall (2), by a line puller (20) mounted inside an interior space (4) of the structure (1) to pull the cofferdam against the wall (2). A connection body (10) is sealingly fixed to the dry side (6) of the wall (2) to enclose the opening (7), and a pressure barrier (21) is sealingly connected to the connection body (10) to exclude water from the interior space 4 during operation of the line puller (20). The line puller (20) may be configured as a winch assembly with a casing forming the pressure barrier (21).
