🔍 Key Concepts
• Salt-Water Service Pump suction and discharge lines on the DEEP DRILLER piping diagram
• Proper valve lineup for filling a specific tank (Tank 1P) from a particular pump
• How valve numbers on the exam diagram correspond to line direction, branch points, and isolation valves
đź’ Think About
• Trace the flow from the Salt-Water Service Pump discharge toward Tank 1P on the piping diagram and identify every valve in that path.
• Ask yourself which valves MUST be open for water to reach Tank 1P, and which valves, if opened, would instead send water to another tank or overboard.
• Check whether the valve in the correct path is a branch, isolation, or overboard valve, and whether opening it would prevent or allow flow to Tank 1P.
âś… Before You Answer
• Verify on the diagram which side of each numbered valve (33, 36, 46, 48) is connected directly or indirectly to Tank 1P.
• Confirm that the chosen valve is on the discharge side of the Salt-Water Service Pump, not on a suction or unrelated line.
• Make sure that opening the chosen valve does not divert flow away from Tank 1P to another destination such as another tank or overboard.
