Which of the following represents an emergency procedure used to stop the oil flow aboard tank vessels, of 250 tons or greater, as required by U.S. regulations?
AI Explanation
The correct answer is C) Quick-acting power actuated valve.
This represents an emergency procedure used to stop the oil flow aboard tank vessels of 250 gross tons or greater, as required by U.S. regulations. Specifically, the regulations mandate that these vessels must be equipped with a quick-acting power actuated valve that can quickly and reliably shut off the oil flow in the event of an emergency.
The other options are incorrect because: A) A self-closing emergency disconnect fitting is not a required emergency procedure, B) A manually-operated quick-closing valve does not provide the same level of reliability and speed as a power-actuated valve, and D) A pressure-sensitive oil pressure controller is not a valve that can directly shut off the oil flow.
