Abstract (en)

[origin: EP0654564A1] In this method for installing the deck (1) of an off-shore platform for a support structure (3) with the aid of a ballastable barge (2) and with the aid of several cylinder and a plunger-piston assemblies (14, 15), it is possible to avoid impacts between pistons (14) and support structure (3) and between the legs (6) of the deck (1) and the support structure (3), which impacts would be due to the vertical movements of the deck brought about by the swell during deck fitting operations, by providing in each leg (6), a low-pressure hydraulic fluid accumulator (17), it being possible for first means (24) to be operated in order to establish a two-way high-flow rate communication between the accumulator (17) and one chamber (16) of a cylinder (15), it being possible for second means (24) to be operated in order to establish a one-way high-flow rate communication from the accumulator (17) towards the chamber (16), and it being possible for third means (25, 35) to be operated in order to establish a low-flow rate communication between the chamber (16) and a hydraulic fluid reservoir (26). <IMAGE>
