Question 1 of 27070

On the DEEP DRILLER, to use the drill water pump to supplement the bilge pumps, it is necessary to open valves 28 and __________.

🔍 Key Concepts

• Bilge and fire main cross-connection arrangements on the DEEP DRILLER piping diagram • Function of the drill water pump versus dedicated bilge pumps • How valve numbering usually relates to line segments and manifold branches on the exam drawing

💭 Think About

• Look at the piping diagram and trace the flow path from the drill water pump discharge toward the bilge suction point. Which valves must be open for water to actually reach the bilge line? • Identify which valve is already part of the bilge system (valve 28) and then find its logical partner in the same branch that completes the connection. • Check whether any choice would accidentally back-feed another system (e.g., fire main only) instead of connecting to the bilge line. Which valve clearly ties the two systems together?

✅ Before You Answer

• Confirm on the diagram that valve 28 is on the bilge side of the cross‑connection, not on the pump discharge itself. • Verify which of the answer‑choice valves (48, 29, 25, 26) is located on the line that directly links the drill water pump discharge to the bilge main near valve 28. • Make sure that opening your chosen valve together with 28 does not bypass the bilge system entirely (for example, send water only to a washdown or fire line).
