The objective of this study is a risk analysis of use of a surface blow out preventer (SBOP). The risk analysis will include the risk of riser failure and take into account high and low bottom-hole pressure, length and type of riser, and the type of vessel (moored or dynamically positioned Mobile Offshore Drilling Unit (MODU), Tension Leg Platform (TLP), Spar, Floating Production Unit ( FPU).
Task 1 Failure Mode Identification
Task 2 Risk Assessment
Task 3 Integrity Management Development
Task 4 Final Report
Key questions to be answered in the Final Report are:Is a surface BOP required for high bottom-hole pressure when drilling in deep water?
Is a subsea shut off/shear device required?
What effect does low bottom-hole pressure have on the risks of using an SBOP?
