To prevent oil from escaping into the sea when ballasting through the cargo piping system, you should FIRST __________.

🔍 Key Concepts

• Sequence of operations when using the cargo piping system for ballasting • Risk of discharging oil overboard if valves are opened or pumps started in the wrong order • Difference between sea suction, sluice valves, and block valves in a cargo/ballast system

💭 Think About

• Think about what could happen if there is still oil in the lines and you open something directly connected to the sea too early. • Which valve operation will ensure that any remaining oil is controlled and contained before you introduce seawater or start pumping? • Consider what must be properly lined up inside the ship BEFORE you create any suction from the sea or start any pumping action.

✅ Before You Answer

• Verify which component, if opened first, would create a direct path from potentially oily cargo lines to the sea. • Confirm which valves are used to isolate and control flow within the ship before connecting to the sea. • Make sure the first step does NOT rely on the pump to be running before the system is safely lined up and isolated.
