Abstract:
1. An instrumentation assembly for use with an offshore riser operated from a floating platform comprising: a system for controlling the riser; a central processing unit for connection by cables to a plurality of modules for fastening to separated points along a length of the riser, the modules comprising measuring units for dynamically locating in real time the points in space and for controlling the system for controlling the riser; another locating module for fastening to a lower end of the riser for locating the lower end of the riser; detectors for measuring environmental conditions; and an assembly for measuring a position of the floating platform; and wherein the central processing unit synchronizes in real time with one another, manages and records measurements from the measuring units, detectors, and assembly and in real time monitors stress, deformation and positions of the riser in controlling the system.
