🔍 Key Concepts

• 33 CFR definitions section for pollution prevention regulations (look at the general definitions, not the operating rules) • How "new ship" is usually tied to a building contract date in international pollution rules (MARPOL influence) • Difference between a ship that is newly built and one that has had a major conversion

💭 Think About

• Ask yourself: in regulations, when they define a "new" ship, do they usually tie it to the date of construction/contract, the date of delivery, or the date of conversion? • Look at the answers that mention major conversion—are those definitions of a "new ship" or are they usually a separate defined term in the regs? • Which option matches how MARPOL/33 CFR often say: "new ship means a ship for which ..."—pay attention to after a certain calendar date wording.

✅ Before You Answer

• Verify what 33 CFR says under the definitions for the particular pollution-prevention subchapter (e.g., 33 CFR Part 151/155). • Check whether "new ship" is defined by the building contract date rather than the delivery date. • Confirm whether major conversion is treated as its own concept ("ship which has undergone a major conversion") instead of being part of the "new ship" definition.
