🔍 Key Concepts

• Ballast system line-up on DEEP DRILLER – which valves connect port pump #2 to the forward-port column ballast tank • Difference between suction valves (from sea or tank) and discharge/column isolation valves (into specific columns or tanks) • How redundancy is arranged: which pumps can serve which columns through crossover valves

💭 Think About

• Trace the flow: starting from port ballast pump #2, what is the path the water will take to reach the forward-port column? Which valves must be open along that path? • Which numbered valves are likely local to the pump, which are cross-connects, and which are column/tank isolation valves? Think about how many of each type you need in series. • Compare the options: which answers either block the flow path or open an unnecessary/conflicting path that wouldn’t be needed just to deballast the forward-port column with pump #2?

✅ Before You Answer

• Verify on the DEEP DRILLER ballast diagram which valves are on port pump #2 suction and discharge lines. • Verify which numbered valves isolate the forward-port column ballast tank from the main ballast line. • Check that the chosen set of valves makes one continuous, unbroken path from pump #2 discharge to the forward-port column, without leaving out a needed valve or adding an extra leg that diverts flow.
