Which method is used to bypass sanctions on petroleum?

• A. By importing oil via sea lanes with lax enforcement.
• B. Ship-to-ship petroleum transfers at sea.
• C. Domestic refining of all imported oil.
• D. Consolidating oil needs within land borders.

Answer: (B)

Sanctions on petroleum aim to prevent certain oil from entering the market by tracing origin, ownership, and transferpoints. A tactic that directly undermines those controls is transferring oil between ships at sea. Ship-to-ship transfers in international waters can hide who supplied the oil and where it’s headed, making it much harder for authorities to trace the cargo and enforce the ban. By moving product offshore, the usual port-of-entry checks and sanctions screening are less effective, enabling continued circulation of restricted oil despite restrictions.

The other options don’t fit this evasive purpose as cleanly. Importing oil through sea routes where enforcement is weaker still relies on lax oversight rather than a deliberate concealment method. Refining all imported oil domestically bypasses import controls only in a processing sense, not in the act of acquiring restricted oil in the first place, and often still falls under sanctions rules. Keeping oil needs within land borders doesn’t address the origin or ownership traceability that sanctions aim to control.
