DNV-RP-E104

Wellhead fatigue analysis

active, Most Current
Publication Date: 1 September 2019
Status: active
Page Count: 159
scope:

This recommended practice provides a consolidated framework for fatigue assessment of subsea and surface well systems during all stages of operation. The described methods cover the following areas:

- computation of both mean and cyclic loads experienced by the wellhead/casing system for each set of conditions

- relationship between cyclic loads and cyclic stresses, such as load-to-stress curves and stress amplification/concentration factors for each location of interest

- damage model, such as S-N approach, initiation life method, and fracture mechanics used to estimate fatigue damage at each location of interest.
