🔍 Key Concepts

• MARPOL regulations on Oil Record Books (especially Annex I) • Which ship types actually handle oil or oily mixtures in normal operations • Whether the requirement depends on vessel type, tonnage, or type of cargo carried

💭 Think About

• Ask yourself: Which of these vessel types routinely have machinery spaces or cargo operations that produce oily residues or discharges that must be documented? • Consider whether the Oil Record Book requirement is tied to being a tanker only, or to any ship over a certain size, regardless of whether it’s cargo or passenger. • Think about how pollution prevention rules try to ensure that every discharge of oily water from machinery spaces or cargo tanks is recorded—on which types of ships would that apply?

✅ Before You Answer

• Check MARPOL Annex I to see if the Oil Record Book is required only for ships that carry oil as cargo or also for ships that use oil as fuel. • Verify whether the regulation is written in terms of gross tonnage and type of trade (e.g., any ship of 400 GT and above, or any oil tanker of 150 GT and above), not just the label ‘cargo’ or ‘passenger’. • Confirm that you are not confusing the Oil Record Book with other documents (like a cargo record book or garbage record book) that may have different ship-type requirements.
