🔍 Key Concepts

• Pollution prevention regulations for machinery space bilges and oil-contaminated water (e.g., MARPOL Annex I principles and equivalent U.S. requirements) • Typical approved ways to handle waste lube oil on board (storage, treatment, and disposal) • The purpose and risks of a vessel’s bilges compared to designated oil or slop tanks

💭 Think About

• Which option describes a practice that would most likely increase the risk of oil pollution or illegal discharge into the sea? • Which choices involve controlled handling of oil (collection, treatment, or reuse) versus simply moving the problem somewhere else? • Think about where oily mixtures are normally allowed to be stored or processed on a compliant vessel.

✅ Before You Answer

• Identify which methods are normally accepted: reclaiming/reusing purified oil, or holding it in designated tanks for proper disposal or processing • Consider the function of slop tanks / waste oil tanks versus general bilge spaces • Ask: From which place on the ship is it hardest to control and monitor oil before it might go overboard? That location is a strong candidate for what is NOT allowed.
