Dispositivo e método de medição do movimento de um duto submarino deformável

摘要

The device (14) has two receiving supports anchored in sea bottom (10) for receiving two deformable submarine flowlines. A divisible, visible and observable element assembly (26) has rods (28) for connecting one submarine flowline and one receiving support (18). The assembly is extended along a mean direction parallel to a determined path. The rods are successively separated by another submarine flowline (12) and another receiving support when the flowlines are driven in movement along the path to measure amplitude of the measurement of the flowlines according to the number of separated rods. An independent claim is also included for a method for measuring the movement of a deformable submarine flowline with respect to sea bottom.
