Aboard the DEEP DRILLER, the bilge pumps...

🔍 Key Concepts

• Typical locations where bilge systems are designed to remove accumulated water on mobile offshore drilling units (MODUs) like DEEP DRILLER • The difference between tanks (for storing liquids) and spaces/compartments (where water might collect unintentionally) • Why chain lockers in columns or void-like spaces are important from a flooding and stability standpoint

💭 Think About

• Ask yourself: Which of these options describes an area where unwanted water could collect and must be pumped out for safety, rather than a tank used for normal operations? • Consider how bilge systems are usually arranged: Do they normally take suction directly from service or drill water tanks, or from spaces that could flood? • Look at the choices mentioning chain lockers. On a column-stabilized unit, where are chain lockers most likely to be considered bilgeable spaces rather than just storage?

✅ Before You Answer

• Verify which option refers to compartments/spaces rather than operational tanks • Identify which chain lockers (if any) are located in areas similar to the voids, cofferdams, and access trunks already listed in the question • Eliminate any choice that is clearly a service tank used for storing water, not a space where bilge suction is normally arranged

Aboard the DEEP DRILLER, the bilge pumps take suction from the pump rooms, cofferdam, void area, access trunk, and which other area?

The backup drill water tank

The forward and after column chain lockers

The primary salt-water service tank
