🔍 Key Concepts

• Deep Driller bilge and ballast piping diagram for the port pump room • Valve line-up required to use the number 1 bilge pump to discharge from the port pump room • Identification of valve numbers on the suction side vs. discharge side of the bilge pump

💭 Think About

• Locate the port pump room bilge suctions on the piping diagram and trace the line back to the number 1 bilge pump. Which specific valve must be open on that suction line? • Follow the discharge path from the number 1 bilge pump to the overboard or bilge manifold. Which valves are common to multiple spaces, and which one is unique to selecting the port pump room? • Compare the valve numbers in the answer choices with the labels on the port pump room suction and the bilge manifold selector valves. Which number appears at the critical selection point for the port pump room when using pump #1?

✅ Before You Answer

• Confirm on the piping diagram which valve number actually selects the port pump room bilge suction for pump #1 (not starboard or centerline). • Verify that the valve you pick is on the correct side of the pump (suction selection, not just any discharge or cross-connect valve). • Make sure the valve number you choose is clearly marked on the Deep Driller drawing as part of the operating lineup for pumping from the port pump room with bilge pump #1.
