Question 1 of 27070

On the COASTAL DRILLER, when afloat, oily bilge discharge should be pumped through the __________.

🔍 Key Concepts

• 33 CFR 155 – Oil or Hazardous Material Pollution Prevention Regulations for Vessels • Purpose of bilge oily-water separators / treatment systems on mobile offshore drilling units (MODUs) • Difference between overboard discharge and approved pollution-control equipment

💭 Think About

• Which system or tank is specifically intended to collect and treat oily mixtures before anything can go overboard? • Which options would send oily water directly to sea versus routing it through a pollution‑control or separation system first? • Think about what the Coast Guard would require on a MODU like COASTAL DRILLER to prevent oil pollution when pumping from bilges.

✅ Before You Answer

• Verify which equipment on a MODU is designed as the pollution‑control path for oily bilge and slop, not just a general piping header. • Eliminate any choice that would allow untreated oily bilge to go straight over the side in normal operations (33 CFR 155.350+). • Confirm which option is commonly connected to oily water separators / recovery systems rather than raw seawater systems or emergency dump arrangements.
