For well control, the American Petroleum Institute recommends that hydraulic units have sufficient horsepower to close the annular preventer in __________.
• API well control recommendations for blowout preventer (BOP) equipment • Typical closure time standards for annular preventers versus ram preventers • The relationship between emergency response and allowed closing time
• Is an annular preventer considered a device that should close relatively quickly or can it take a long time in an emergency? • Among the choices, which time would still be fast enough to control a sudden influx but not so short that it risks damage from overly rapid closure? • How do recommended closure times for an annular preventer generally compare to those for other BOP components?
• Confirm in your notes or manual what API recommended closing time is for annular preventers specifically, not just generic BOPs • Check whether API emphasizes rapid but controlled closure for annulars, and which option best reflects that balance • Verify that the time you choose matches standard training and exam references used for offshore well control coursework
