The purpose of this technical report is to document methods of reliability analysis for well control equipment systems installed for drilling wells.

Well control equipment systems are designed with components that provide wellbore pressure control in support of well operations. As an example, the following typical systems were modeled and analyzed:

― Surface On-Shore BOP Systems.

― Surface Off-Shore BOP Systems.

― Subsea BOP System with Discrete Hydraulic Control System.

― Offshore DP MODU with a Subsea BOP System with Electro-hydraulic/Multiplex Control System.

Fault trees were developed based on generic (non-original equipment manufacturer specific), and limited to, well control equipment components with a top event of “failing to seal and secure the well” (see Annex B, Annex C, and Annex D). This technical report did not include consequence analysis. The intent of the models is to identify the system’s ability to perform its intended function and document the individual components importance and percentage failure contribution to the top event.

The fault trees only analyze the probability of sealing a well, and do not address non-productive time.
