Rising U.S.–Venezuela Tensions: Maritime Security Implications for Navigators in the Caribbean

Tensions between the United States and Venezuela have escalated significantly over recent weeks, with developments that are increasingly relevant for maritime traffic in the Caribbean Sea. While no formal declaration of war has been made, a combination of U.S. enforcement actions at sea, heightened military activity, and strong political rhetoric from Caracas has created a volatile operating environment for commercial and private vessels.

For navigators, this situation represents a maritime security risk scenario, rather than a conventional armed conflict.

 U.S. Interdiction and Seizure Operations
According to Reuters, the United States has already seized at least one tanker carrying Venezuelan oil and is preparing to seize additional vessels suspected of violating sanctions. These actions are being conducted under the justification of sanctions enforcement and counter-narcotics operations.

From a maritime perspective, this signals:

• Increased boarding and interdiction activity

• Higher scrutiny of tankers, cargo vessels, and support ships operating near Venezuelan waters

• Potential legal and operational delays for vessels transiting the area

Venezuelan Government Response
The Venezuelan government has issued an official communiqué accusing the U.S. of:

• Violating international law

• Threatening freedom of navigation

• Preparing what Caracas describes as a “naval blockade”
  

Venezuela has stated it will defend its sovereignty and has announced that its Ambassador to the United Nations will formally denounce U.S. actions. While largely diplomatic in nature, this rhetoric increases the risk of miscalculation or aggressive posturing at sea.

Increased Military Presence and Incidents
The region has seen:

• Expanded U.S. naval and air operations in the southern Caribbean

• A near midair collision involving a commercial JetBlue flight and a U.S. Air Force refueling tanker near Curaçao, highlighting congestion and complexity in the operational environment

• Reports of military aircraft operating without active transponders during missions

These factors raise concerns not only for aviation, but also for vessels relying on predictable military traffic patterns and clear maritime domain awareness.

Current Risk Assessment for Mariners

Conflict status:

• No confirmed naval blockade or declared exclusion zone

• No verified large-scale hostilities underway

Operational risk level:

• Medium and increasing, especially within 100–150 nautical miles of the Venezuelan coast

Primary risks for vessels:

• Boarding or diversion by U.S. forces

• Delays due to inspections or investigations

• Heightened surveillance and electronic monitoring

• Risk of being misidentified or questioned due to AIS irregularities

• Increased air and naval traffic raising collision or near-miss risk

Areas of Particular Attention

Navigators should exercise enhanced caution in:

• The Gulf of Venezuela

• Waters north of Puerto Cabello and Maracaibo

• Sea lanes between Venezuela, Curaçao, Aruba, and Trinidad

• Approaches to ports linked to oil, refined products, or sanctioned trade

Operational Recommendations for Navigators

• Maintain continuous AIS transmission unless legally justified otherwise

• Ensure all ship documentation, cargo manifests, and routing data are accurate and readily available

• Closely monitor NAVTEX, NAVAREA warnings, and flag state advisories

• Avoid loitering or unnecessary deviations near Venezuelan territorial waters

• Be prepared for radio contact or inspection requests by naval or coast guard units

• Review contingency plans for diversion, detention, or inspection delays

At present, the situation appears to remain in a phase of maritime coercion and pressure, rather than open conflict. However, the combination of enforcement actions, political escalation, and military presence increases the likelihood of localized incidents, particularly affecting commercial shipping.

Navigators should treat the southern Caribbean as a heightened-risk operational area and remain alert to rapid changes in rules of engagement or enforcement posture.
