## Abstract

This rule amends the regulations governing the testing requirements for BOP systems used in drilling and completion operations on the Outer Continental Shelf (OCS). The rule allows a lessee up to 14 days between BOP pressure tests. MMS based this rule on a study of BOP performance which concluded that no statistical difference exists in failure rates for BOP's tested between 0- and 7-day intervals and between 8- and 14-day intervals. MMS estimates that the 14-day testing requirement could save industry $35 to $46 million a year without compromising safety.
