Title 46 › Subtitle II — Vessels and Seamen › Part B — Inspection and Regulation of Vessels › CHAPTER 37 — CARRIAGE OF LIQUID BULK DANGEROUS CARGOES › § 3705
New crude oil tankers of at least 20,000 deadweight tons must have protected segregated ballast tanks, a crude‑oil washing system, and cargo tank protection made of a fixed deck froth system plus a fixed inert‑gas system. Existing tankers 40,000 deadweight tons or more must have segregated ballast tanks or crude‑oil washing; vessels 20,000–under 40,000 that are at least 15 years old must too. All existing tankers of 20,000 deadweight tons or more must have an inert‑gas system, but the Secretary may exempt ships under 40,000 without high‑capacity tank washers if compliance is clearly unreasonable because of the ship’s design. Tankers taking oil from U.S. offshore facilities must use segregated ballast tanks or dedicated clean or special ballast arrangements and still meet the other standards.
