Question 1 of 27070

Failure of both port ballast pumps on the DEEP DRILLER prevents their use. To deballast from tank 1P, you may use the __________.

🔍 Key Concepts

• Ballast system arrangements on mobile offshore drilling units (MODUs) like DEEP DRILLER • Use of crossover lines/manifolds between port and starboard ballast systems • Differences in intended service between ballast pumps, bilge pumps, drill water pumps, and saltwater service pumps

💭 Think About

• Which system is specifically designed to move large quantities of water to control draft and trim in tanks like 1P? • If one side’s dedicated pumps fail, what piping feature would allow another pump to take suction from or discharge to that tank? • Which pumps are normally restricted from use for ballast or tank transfer because of contamination or regulatory/safety reasons?

✅ Before You Answer

• Confirm which pump(s) are connected to the ballast manifold and crossover system on a MODU like DEEP DRILLER • Check which systems are normally not approved or not piped for ballast transfer (e.g., bilge, fire/saltwater service, drill water) • Verify from the piping diagram which pump can actually take suction from tank 1P if both port ballast pumps are out of service
