MARINE RISER COMPONENT AND METHOD OF ASSESSING FATIGUE DAMAGE IN A MARINE RISER COMPONENT

摘要

A marine riser component which has an integrated fatigue damage sensor in which the sensor is adapted to be damaged by stresses and strains applied to the marine riser component, and is adapted to record said damage on the sensor. The sensor is optionally integrated into the body of the marine riser component in a location on the component that transmits fatigue loads to the sensor at a known stress concentration factor, optionally in a recess on the body, for example, in a closed recess on an outer surface of the marine riser component.
