Abstract
Current profile of water (e.g., ocean) around a riser connected to a wellhead may be measured and used to determine integrated current load on the riser at any given moment in time. The integrated current load may be used to estimate the wellhead fatigue damage rate at that moment in time. The estimated wellhead fatigue damage rate may be used to make operational decisions for the well.
