Question 3237 Deck General

The correct answer is B) 30 seconds. The American Petroleum Institute (API) recommends that hydraulic units have sufficient horsepower to close the annular preventer in 30 seconds. This is a standard requirement to ensure that the well can be shut in quickly in case of an emergency, preventing the uncontrolled release of fluids and potential blowout. The other options are incorrect because 15 seconds is too fast, 45 seconds is too slow, and 60 seconds is also too slow for the recommended well control standards set by the API.
