🔍 Key Concepts

• Trace the flow path from the sea chest, through the pump, to the #6 port and starboard wing tanks • Identify which valves are on the suction side (from sea chest to pump) and which are on the discharge side (from pump to cargo tanks) • Remember you want to fill only the #6 port and starboard wing tanks, not the center tank or deck lines

💭 Think About

• Starting at the sea chest, which valves must be open so the pump can actually take suction from the sea? • From the pump discharge, which single line leads toward the #6 cargo tanks, and which valves must stay closed so water does NOT go to the center tank or main deck lines? • Looking at the branches going to #6 port, center, and starboard, which two valves must be open so only the wing tanks receive ballast?

✅ Before You Answer

• Be sure the sea chest isolation valve and at least one suction valve to the pump are open • Confirm the deck cargo line valves and the #6 center tank valve are closed so they cannot receive ballast • Verify that the valves on the lines directly into #6 port and #6 starboard are both open, and that the main cargo line into the #6 tanks is open upstream of those branches
