Abstract
A sensor for sensing deflection/curvature of underwater riser pipes comprises a metal tube which is strapped to the pipe, with the tube being parallel to the length of the pipe. The tube is fitted internally with strain gauges which measure the deflection of the tube and thus of the pipe on which it is mounted. The tube is filled with oil and is connected to a plastics tube which can deform to recta to hydrostatic pressure at different water depths.
