🔍 Key Concepts

• redundancy of pumping systems on MODUs (Mobile Offshore Drilling Units) • how ballast systems and crossovers can be used for emergency dewatering • limitations on using service/drill water/saltwater pumps for bilge or flooding control

💭 Think About

• Which pump and piping arrangement can actually draw from the flooded space (port pump room) and discharge overboard or to another tank, given the failure of both port bilge pumps? • Think about which choice gives you an independent suction source and piping run, not relying on the already-failed side of the system. • Is there a way to use the opposite side of the unit plus a crossover to reach the flooded compartment when the local pumps are inadequate?

✅ Before You Answer

• Check which systems are normally connected to the bilge or ballast cross‑connect manifolds on a drilling unit. • Verify which pumps are likely to be sea‑water only and not arranged for bilge suction from a pump room. • Confirm which option provides the most flexible suction and discharge routing in an emergency, not just more capacity on the same side.
