Info

BOP Limitations and Reliability • Maximum BOP pressure rating is struggling to keep pace with drilling technology • Shear rams cannot cut through some drillstring components (e.g. drillpipe connections) or certain extraordinary obstructions in the bore of the BOP • Routine full emergency testing of all functions is not deemed to be practicable • Despite continuing R&D by the BOP manufacturers, component failures are random events and may still occur
