Title 46 › Subtitle Subtitle II— - Vessels and Seamen › Part Part B— - Inspection and Regulation of Vessels › Chapter CHAPTER 37— - CARRIAGE OF LIQUID BULK DANGEROUS CARGOES › § 3705
New crude oil tankers of at least 20,000 deadweight tons must have segregated ballast tanks placed for protection, a system that washes the cargo tanks with crude oil, and cargo-tank protection made up of a fixed deck froth device plus a fixed inert gas system. Existing tankers 40,000 deadweight tons or more must have either segregated ballast tanks or a crude oil washing system. Existing tankers 20,000 to less than 40,000 deadweight tons that are 15 years old or older must have one of those two systems. All existing tankers of at least 20,000 deadweight tons must have an inert gas system, but the Secretary can allow an exemption for vessels under 40,000 tons that lack high‑capacity tank washers if the owner proves compliance would be unreasonable because of the ship’s design. Tankers transferring oil from an offshore facility on the Outer Continental Shelf of the United States must use segregated ballast tanks or dedicated clean ballast tanks or special ballast arrangements, and must meet the other minimum standards above.
