Abstract:
A clamp system installed on a floating support enabling a pipe to be held under tension, the system comprising:a tubular element suitable for containing said pipe and secured to said floating support; said tubular element containing a plurality of friction shoes, each of said shoes being mounted on the end of a piston of a hydraulic actuator; said actuators and shoes being disposed in a plurality of planes of said tubular element along the longitudinal axis of said tubular element, and being distributed in each of said planes around said pipe; and said pistons moving in translation in a direction substantially perpendicular to said longitudinal axis of said tubular element, whereby: said friction shoes are in a clamping position against said pipe when said pistons are in an extended position, and said shoes are in a position disengaging and releasing said pipe when the pistons are in a retracted position; and each actuator is provided with mechanical means for locking said piston in the extended position.
