My-Spread Forum | BOP Test Pressure Policy

We are seeking to optimize BOP test times by simultaneously testing the choke manifold at surface and the BOP downhole within the same test. An issue that we face is that for some tests, the Maximum Anticipated Pressure at surface plus the hydrostatic of the fluid in the choke lines exceeds 15,000 psi INTERNAL pressure downhole (rated working pressure of the BOP).
