DNV GL establishes recommended practice to manage wellhead fatigue analysis

摘要

Addressing wellhead fatigue issues and proving sufficient margin for drilling operations has been a growing challenge for the oil & gas industry over the last decade. Wellhead fatigue can have significant technical, financial and safety implications for the system. In close cooperation with industry partners, DNV GL is addressing this issue through an ongoing joint industry project (JIP). This has resulted in a new recommended practice (RP) addressing the structural loading of offshore well systems.
