🔍 Key Concepts

• Follow the suction piping from the lube oil drain tank cofferdam all the way to the bilge pump suction inlet on the GS-0042 diagram. • Notice where the suction line joins a bilge/ballast suction manifold and whether there is a separate tank isolation valve plus a manifold suction valve. • Distinguish carefully between suction-side valves and discharge-side valves on the bilge pump symbol.

💭 Think About

• Starting at the lube oil drain tank cofferdam, how many valve symbols must liquid pass through before it reaches the bilge pump casing? • Does the suction line from the cofferdam go directly to the pump, or does it first connect into a common manifold that itself has a suction valve at the pump? • Are there any valves drawn on branches that are not actually in the active flow path when you are pumping from the cofferdam to overboard or to another destination?

✅ Before You Answer

• Verify you are only counting valves that are upstream of the pump (on the suction side), not those on the discharge or overboard line. • Confirm whether the cofferdam connection has its own dedicated isolation valve in addition to any manifold valves. • Double-check that each valve symbol you count is actually in series in the line from the cofferdam to the pump, not in parallel or on a different branch.
