Method and system for fatigue monitoring of submarine cables in offshore operation

摘要

The present disclosure relates to a method for monitoring fatigue of a submarine cable during sea joining or repair, the method comprising: a) determining a plurality of curvature values for the curvature of the submarine cable 9 at different points in time during sea joining or repair. Step b) determining a plurality of strain ranges of the submarine cable 9 based on the plurality of curvature values, and c) fatigue damage of the submarine cable 9 based on the plurality of strain ranges And determining.
