MASP is the calculated maximum internal pressure that the blow-out preventer (BOP) and related equipment will be subject to while conducting well operations. MASP establishes pressure ratings for surface and mud line equipment and is then used to set pressure test schedules for that equipment, e.g., choke and kill (C&K) manifold and BOP testing.
On subsea BOPs, the term is “Maximum Allowable Water Pressure” (MAWP).
