marine riser component and method for assessing fatigue damage in a marine riser component

摘要

It is a marine riser component having an integrated fatigue damage sensor, wherein the sensor is adapted to be damaged by stresses and deformations applied to the marine riser component, and is adapted to record said sensor damage. the sensor is optionally integrated with the marine riser component body at a component location that transmits fatigue loads to the sensor under a known stress concentration factor, optionally a body recess, for example, a closed recess on a surface of the marine riser component.
