Abstract
The wave characteristics of the water (e.g., ocean) above a wellhead may be used to determine a wave-induced wellhead fatigue damage rate for the wellhead, and the current profile of water around a riser connected to the wellhead may be used to determine a riser vortex-induced vibration caused fatigue damage rate for the wellhead. The wave-induced wellhead fatigue damage rate and the riser vortex-induced vibration caused fatigue damage rate for the wellhead may be combined to obtain the total wellhead fatigue damage rate for the wellhead, which may be used to make operational decisions, such as connections or disconnections, for the well.
