Abstract
A method of maintaining a rod of a hydraulic cylinder for a motion compensation system of an offshore platform includes non-destructive testing of a metallic cladding deposited onto the rod. An inspection crawler includes a visual inspection device, an eddy current inspection device and an ultrasonic inspection device. The method includes rotating the visual inspection device, the eddy current inspection device and the ultrasonic inspection device around a circumference of the rod while moving the inspection crawler along a longitudinal axis of the rod to simultaneously collect data related to the metallic cladding from the visual inspection device, the eddy current inspection device and the ultrasonic inspection device. The data is analyzed to detect any discontinuities, i.e., defects, in the metallic cladding.
