Design validation performance testing completed in accordance with API-16A requirements:

API-16A qualification tests performed:

  Test Performed Test Description
Factory Acceptance Testing The Factory Acceptance Test includes testing on pipe to low (200-300 psi) and high (5000 psi) wellbore pressure, Complete Shut-off (CSO) test to 2500 psi wellbore pressure and drift testing within 30 minutes.
Temperature Testing Verifies the performance of non-metallic seals and molded sealing assemblies used as pressure-controlling and/or pressure-containing during exposure to low (40°F) and high (350°F) temperatures
Fatigue Testing Simulates closing and opening the blowout preventer once per day and wellbore pressure testing at 200 psi to 300 psi and full rated working pressure once per week, for one year of service. Target 52 API cycles (7 open/close cycles = 1 API cycle)
Sealing Characteristics Testing This test determines the piston closing pressure necessary to maintain a seal as a function of wellbore pressures up to full rated working pressure of the blowout preventer.
Stripping Life Testing Determines the ability of the annular packing unit to maintain control of wellbore pressure while stripping drill pipe and tool joints through the closed packing unit without exceeding a leak rate of 4 liters/min. (1gal/min).
Coming Soon Continuous Operation Temperature Testing This test determines the ability of the annular packing unit to maintain a wellbore pressure seal after repeated closings and openings at the continuous elevated rated temperature and rated working pressure.

*All qualification tests are performed following API-16A industry test procedures and qualification requirements.

**With the exception of stripping test, the acceptance criterion for all tests to verify pressure integrity was zero visible leakage.
