🔍 Key Concepts

• Purpose and typical uses of a drill water pump on an offshore drilling unit like DEEP DRILLER • Difference between bilge, ballast, and drill water systems • Which systems are normally designed to share pumps and which are kept separate for safety/contamination reasons

💭 Think About

• Think about what kind of liquid the drill water pump is intended to handle and where that liquid is usually needed besides the drill floor/deck • Ask yourself which of the listed systems (bilge, ballast, deck saltwater, fuel-oil recovery) would be acceptable to connect to a drill water system without creating contamination or stability risks • Consider normal emergency and routine operations: in which of these situations would having drill water readily available through this pump be most logical and useful?

✅ Before You Answer

• Verify which systems on an offshore unit are usually kept separate for stability reasons (e.g., ballast vs. drill water) • Consider whether it is safe or standard practice to use a drill water pump for fuel-oil recovery or bilge, given pollution and fire risks • Check which option most closely matches a routine service function rather than an unusual or high‑risk cross‑connection
