🔍 Key Concepts

• Deck pollution prevention under MARPOL and company procedures • Difference between preventing a spill from reaching water vs. cleaning it up after it’s in the water • How oil is normally contained and collected on deck (scuppers, drip pans, drains)

💭 Think About

• Which choice actually stops oil on deck from flowing overboard into the sea, rather than dealing with oil already in the water? • Think about where deck scuppers and drains lead—what happens if oil reaches them during rain or washdown? • Which option would be used routinely during operations, not just during a large spill response?

✅ Before You Answer

• Identify which option acts at the deck level before oil can escape over the side • Distinguish between equipment used for sea surface clean‑up and equipment used for onboard containment • Consider normal ship practice during bunkering or cargo ops: what do you do with scuppers and deck drains to prevent pollution?
