U.S. Naval Moves Against Venezuela: Escalation in Maritime Sanctions Enforcement

Context:
The United States has significantly escalated naval actions against Venezuela by intercepting and seizing multiple oil tankers linked to Venezuelan crude exports, as part of a broader sanctions enforcement and economic pressure campaign. These actions highlight rising geopolitical tension and the use of naval power to enforce sanctions in international waters, with implications for international law, trade, and regional stability.

Key Highlights:

Tanker Seizures and Interceptions

• The U.S. seized the oil tanker Skipper off the coast of Venezuela in December 2025; the vessel was carrying Venezuelan crude and was part of Washington’s targeted pressure campaign.

• The Panama-flagged tanker Centuries was stopped and boarded by U.S. Coast Guard forces as part of the Venezuelan oil blockade enforcement.

• The Russian-flagged tanker Marinera (formerly Bella 1) was seized in the North Atlantic after a pursuit by U.S. authorities; it was accused of violating sanctions and linked to shadow fleet operations.

Sanctions and Strategic Objectives

• These operations are part of a blockade and enforcement strategy under the U.S. policy to limit Venezuela’s oil revenues and sanction evasion.

• The U.S. has targeted vessels associated with the “shadow fleet”—shipping networks used to transport oil for sanctioned states like Venezuela, Iran, and Russia.

International Law and Maritime Issues

• Under the United Nations Convention on the Law of the Sea (UNCLOS), ships without valid flag registration may be boarded on suspicion of illegal activities.

• Venezuela and other critics have labelled some U.S. actions as “piracy” or violations of maritime norms.

Mechanisms of Enforcement

• U.S. Coast Guard and naval units are central to interdictions, supported by intelligence and legal instruments such as OFAC sanctions and judicial seizure warrants.

• Shipping insurance and classification society withdrawal (by Western entities) affects sanctioned vessels’ operability and increases vulnerability to interdiction.

Challenges to Sanctions Effectiveness

• Countries targeted by sanctions often use alternative shipping networks and cooperative arrangements to circumvent restrictions, diluting the effectiveness of U.S. pressure.

• Legal contests (e.g., asylum claims by seized crew members) reflect complex legal repercussions of maritime enforcement beyond geopolitics.
