Calculating Wellhead Fatigue Engineer Live Fugro has completed a year long wellhead monitoring project for bp americas inc, measuring blowout preventer (bop) stack motions and calculating wellhead fatigue during a deployment in the gulf of mexico. Therefore, it is necessary to propose a management and control approach for sws fatigue life that can effectively identify the fatigue status of sws and mitigate the likelihood of fatigue failure.
Trendsetter Vulcan Offshore Deploys A Wellhead Fatigue Mitigation To address these limitations, a web based tool hosting machine learning (ml) models was recently developed to assess the wellhead fatigue damage in a less conservative, real time manner and comes at no incremental cost to end users. The results for wave and vortex induced vibration (viv) fatigue life based on measured acceleration data are calculated, and the fatigue bias with predicted results are summarised.

Subsea Wellhead Fatigue Analysis And Design With Fea Sumitomo heavy industries marine engineering , japan. in 2005, he joined exxonmobil projects. since 2010, he has a contract with department of aeronautical, automotive, and ocean engineering, faculty of mechanical engineering. he is also appointed as head of high performance computing, cict, universiti teknologi malaysia. supported by. This paper presents an integrated approach to comprehensively predict the fatigue damage and reliability of subsea wellhead systems and diagnose the underlying root cause during its service life. This recommended practice provides a consolidated framework for fatigue assessment of subsea and surface well systems during all stages of operation. This study investigates the fatigue behavior of subsea wellhead systems under dynamic loading by integrating analytical models with matlab based simulations. This paper combines the theoretical nonlinear fatigue accumulation model proposed by huffman and beckman (2013) with decoupled analysis to evaluate the fatigue life of subsea wellhead welds in drilling and completion conditions while comparing the findings with the traditional s–n curve method. The paper provides background and introduction to the improved analysis methodology and relevant s n curves for high strength steels for wellhead systems, given in the 2019 version of the dnvgl rp c203.
