Abstract:
The assembly includes a one group (40A to 40C) of hydraulic shock absorbers (42), each shock absorber (42) comprising a hydraulic jack comprising a cylinder designed to be supported by the first element (14), and a shock-absorbing member partially received in the cylinder. The shock-absorbing member has a head protruding outside the cylinder, the head being designed to come into contact with the second element during mounting of the second element on the first element (14).The shock-absorbing assembly (17) includes, for each group (40A to 40C) of shock absorbers (42), a fluid accumulator (44) connected to each cylinder of the group of shock absorbers (42), to allow a hydraulic fluid transfer between the different cylinders of the group of shock absorbers (42) during contact between each head and the second element.
Abstract:
A method for installation of an elongate element in a stretch of water, the method including reversible fastening of a connecting member (34) at a first end (16) of the elongate element (10); arranging the elongate element (10) in a substantially horizontal configuration; reversibly engaging the connecting member (34) in a retaining member (36); pivoting the elongate element (10) about a substantially horizontal axis to move the elongate element (10) into a substantially vertical configuration, while the connecting member (34) remains engaged in the retaining member (36); joint lowering of the retaining member (36), the connecting member (34) and the elongate element (10) in the stretch of water (12) with the help of a lowering line (152); detaching the connecting member (34) of the first end (16) of the elongate element (10), and joint raising of the retaining member (36) and the connecting member (34).
