Question 54 RVR05 - Master of LT 100 GRT

The Correct Answer is C **Why option C ("Discharge to a proper reception facility") is correct:** Waste oil (including sludge, bilge water, and residues from fuel operations) is classified as an oily mixture or pollutant under international maritime law, specifically the MARPOL convention (Annex I). Disposing of this waste at a proper shore-side reception facility is the internationally recognized and legal method for handling ship-generated oil waste. These facilities are equipped to safely process, treat, or dispose of the oil without polluting the marine environment. **Why the other options are incorrect:** * **A) Mixing it with dispersants before draining it overboard:** This method constitutes the deliberate discharge of an oily mixture into the sea, which is prohibited under MARPOL Annex I regulations, except under very specific and controlled circumstances (which do not apply to routine waste oil disposal). Dispersants do not eliminate the oil; they just break it into smaller droplets, potentially increasing its harmful impact on marine life. * **B) Adding sinking agents and discharging it into the water:** This is an illegal and environmentally destructive method. Sinking agents cause the oil to settle on the seabed, where it can smother benthic organisms (bottom dwellers) and contaminate the marine ecosystem for long periods. * **D) Draining it overboard when the vessel gets underway:** The intentional discharge of waste oil overboard is strictly prohibited, regardless of whether the vessel is underway or stationary, except when following specific regulatory criteria for treated bilge water (which waste oil or sludge rarely meets). Draining pure waste oil overboard is illegal pollution.
