Summary
This alert examines capping-stack deployment where a 15,000 psi BOP contains a lower-stack annular preventer rated to 10,000 psi. For the described HPHT blowout configuration, it identifies the wellhead connector, after lower BOP removal, as the only attachment position tested to 15,000 psi, and requires consideration in oil-pollution emergency response strategies.
