🔍 Key Concepts

• Bilge system line-up diagrams for the DEEP DRILLER • How numbered valves correspond to specific compartments (port pump room vs. other spaces) • Relationship between the number 2 bilge pump suction manifold and individual bilge suction valves

💭 Think About

• On a typical bilge system, how do you trace which valve connects the selected pump (number 2) to the port pump room bilge suction? • Looking at the DEEP DRILLER’s bilge and ballast diagram, which valve number is shown on the port-side bilge suction line from the port pump room to the common manifold? • Are there any valves in the choices that clearly belong to a different space or function (e.g., starboard side, engine room, ballast line)?

✅ Before You Answer

• Confirm on the bilge system schematic which valve number is labeled on the port pump room bilge suction going to bilge pump #2. • Verify that the chosen valve is on the port side, not starboard, and is a bilge suction, not a discharge or ballast valve. • Make sure there is no additional isolation valve in that line that would change which valve must be opened for suction from the port pump room.
