Abstract: A computing system, method, and computer-readable medium includes a fatigue tracking service that assists with monitoring fatigue damage in a subsea wellhead system. The fatigue tracking service uses historical environmental data to determine a fatigue damage rate. The fatigue tracking service determines a fatigue allowance based upon the fatigue damage rate, a number of days assigned to a well operation, and a total allowable fatigue damage. The fatigue tracking service compares the fatigue allowance to measurements providing an accumulated fatigue damage to facilitate the monitoring of fatigue damage in the subsea wellhead system.
