Asecure the burner and determine the cause of the valve failure
Bwedge the valve in the open position and report it to the chief engineer
Cwedge the valve in the open position and reduce the fuel oil pressure at that burner
Dbypass the solenoid valve and enter the fact in the logbook
AI Explanation
The correct answer is A) secure the burner and determine the cause of the valve failure. When a burner fuel oil solenoid valve continually trips closed under normal steaming conditions, it indicates a problem with the valve or the automation system. The proper response is to secure the burner, as continuing to operate with a malfunctioning valve could lead to a dangerous situation. The root cause of the valve failure should then be investigated and addressed, rather than simply bypassing or wedging the valve open, which could lead to further issues. The other options are incorrect as they do not properly address the safety concerns and underlying problem.
