Using Windward’s Early Detection solution, this report examines a series of emerging anomalies in global maritime oil trade following recent U.S. enforcement escalations involving Venezuela. Early Detection surfaces deviations from historical baselines and expected movement patterns, often acting as a leading indicator of shifting maritime behavior before structural change is visible.

The anomalies highlighted in this report do not yet confirm a reconfiguration of global oil flows. However, taken together, they suggest that operators linked, directly or indirectly, to Venezuelan crude may be modifying behavior in response to heightened compliance pressure and geopolitical uncertainty.

While Venezuela-related sanctions may be subject to change, the operational behaviors observed in this report reflect real-time adjustments in the maritime domain following enforcement actions as of late 2025 and early 2026.

Initial Enforcement Shock and Disruptions Patterns

Following the U.S. enforcement escalation in December 2025 targeting Venezuelan oil shipments, Early Detection flagged multiple irregularities across known trade routes. Several Venezuela-linked tankers, including Skipper, Centuries, M Sophia, Marinera (Bella 1), and Olina, were observed reversing course, suspending navigation, or deviating from expected trajectories.

These disruptions coincided with vessel interdictions and reported seizures, collectively indicating a short-term operational breakdown in routine export behavior. While the duration and downstream effects are still unfolding, a temporary stranding of Venezuelan crude appears likely.

Malaysia as a Tactical Coordination Zone (Early Indicators)

Early Detection identified a cluster of behavioral anomalies in Malaysia’s Exclusive Economic Zone (EEZ) during the first week of January 2026, involving vessels with Venezuela compliance exposure. While vessel counts remain modest, the convergence of multiple red flags within a narrow time frame is notable.

Flagged anomalies include:

• A 105% increase in low-speed operations, indicative of loitering or rendezvous behavior.
• A 165% spike in extended anchored, breaking previously stable baselines.
• A 335% surge in ship-to-ship transfers.

While each anomaly could represent a transient operational delay, their collective emergence in a known deceptive shipping corridor, combined with the timing of U.S. actions, suggests a tactical response to enforcement, not random deviation.

Early Pullback by Russia-Linked Vessels in Venezuelan Waters

Meanwhile, Early Detection observed a notable reduction in ship-to-ship meetings involving vessels with Russia General compliance risk within Venezuela’s EEZ during early January 2026. Activity declined approximately 46% compared to expected baselines, reversing months of elevated presence since mid-2025.

This drop coincides with recent vessel seizures, leadership changes in Venezuela, and rising enforcement pressure. While the trend may prove temporary, it indicates that some operators are voluntarily reducing exposure in high-risk zones.

Preliminary Assessment

At this stage, the signals should be interpreted as early, behavior-based indicators, not definitive proof of trade reconfiguration.

Taken together, the data suggest:

• Short-term disruption is real, even if long-term trade patterns are unclear.
• Operators are testing alternative routes and jurisdictions.
• Risk is dispersing geographically, with some areas seeing early concentration while others are experiencing a pullback.

Ongoing monitoring will determine whether these adaptations become sustained or recede once pressure stabilizes.

Applying Remote Sensing Intelligence to Venezuela’s Maritime Domain

Contextualizing Early Detection Signals with Satellite Imagery

To validate the Early Detection anomalies flagged within Venezuela’s EEZ, Windward analyzed targeted satellite imagery collections across areas where the ship-to-ship clusters were detected. These collections provide operational context, not evidence of confirmed violations.

Cluster 1: Offshore Puerto La Cruz

Satellite collection: January 5, 2026 | 12:50 UTC

One cluster of ship-to-ship meetings is located offshore Puerto La Cruz, an area repeatedly flagged by Early Detection due to ship-to-ship activity involving vessels with Russia General compliance risk.

Object detection analysis surfaced dozens of maritime objects, many of which did not correlate with AIS transmission, a key indicator of dark operations.

Within this environment, the imagery reveals multiple close-proximity interactions consistent with ship-to-ship activity, including:

• A tanker-to-tanker meeting between a Venezuela-flagged tanker (~75m) and a Comoros-flagged tanker (~160m).
• A semi-dark rendezvous between a Tanzania-flagged service vessel (~39m, AIS on), and a larger dark vessel (~140m).

While imagery alone cannot determine cargo transfer or intent, the co-location of dark vessels, mixed-flagged tankers, and service craft in a confined offshore area reinforces the behavioral anomalies surfaced by Early Detection.

Cluster 2: Offshore Punto Fijo

Satellite collection: January 6, 2026 | 15:12 UTC

A second satellite collection captured another concentration of maritime activity offshore from Punto Fijo, further west along Venezuela’s coastline. This area had also been flagged by Early Detection for anomalous ship-to-ship activity involving vessels with Russia General compliance risk.

The imagery reinforces the pattern seen in Puerto La Cruz. Object detection analysis identified multiple vessels operating in close proximity, while an AIS overlay revealed missing transmission across the cluster. Several vessels were fully dark, while others broadcasted intermittently or appeared under inconsistent identifiers.

This fragmented visibility paints a layered and complex operational picture, where:

• Some vessels broadcast AIS normally.
• Others transmit intermittently or switch off mid-operation.
• Multiple detected vessels had no AIS signal at all.

While the imagery does not confirm the intent or specific cargo movement, it visually aligns with the Early Detection signal. It highlights the challenges of monitoring activity in a crowded, low-transparency, maritime environment, where attribution, enforcement, and situational awareness are all degraded.

Reinforcing the Pattern

Taken together, the imagery from Puerto La Cruz and Punto Fijo demonstrates repeated clustering of vessels exhibiting deceptive patterns, mixed dark and transmitting operations across zones, and a low-transparency maritime environment complicating attribution and assessment.

AIS data alone fails to provide a complete view. These visuals reinforce, not replace, the Early Detection signal, offering a snapshot of the complex surface picture.

Interpreting the Operational Environment

Imagery confirms that Venezuela’s offshore waters are marked by:

• High vessel density.
• Partial or absent AIS signals.
• Frequent close-proximity interactions among tankers and auxiliary vessels.

These conditions significantly degrade situational awareness, especially when relying on AIS alone. The presence of dark and semi-dark vessels complicates real-time attribution, monitoring, and response, particularly during periods of heightened enforcement.

Importantly, this imagery should be understood as a contextual indicator that supports the Early Detection signal, rather than as confirmation of specific illicit activity. It offers a real-world snapshot of the environment in which anomalous maritime behaviors are unfolding.

Early Signals, Real-World Context

This report combines insights from Windward’s Early Detection solution with targeted satellite imagery collections to surface initial behavioral indicators following recent U.S. enforcement actions involving Venezuela. Together, these inputs provide a leading-edge view of potential maritime adaptation without asserting long-term structural change.

As global enforcement priorities shift, the value of behavioral indicators increases. Whether sanctions frameworks are tightened or relaxed, Early Detection provides a critical lens into how operators respond on the water, insight that remains relevant regardless of policy changes.

Early Detection Is Surfacing Initial, Behavior-Based Signals

Windward’s Early Detection flagged multiple anomalies across regions and behaviors, from ship-to-ship activity and routing deviations to AIS suppression and shifting vessel interactions, following geopolitical escalation and enforcement events in Venezuela.

Each anomaly reflects a departure from historical baselines and may signal early operational adaptation under pressure, rather than random or isolated disruption.

These patterns should be viewed as leading indicators: they surface where maritime behavior is changing first, before trade routes visibly shift.

Remote Sensing Intelligence Offers Operational Context

Targeted satellite collections across Venezuela’s EEZ provide environmental context for behavioral anomalies detected. Imagery consistently shows:

• High vessel concentration in constrained offshore zones.
• Mixed visibility environment with dark, semi-dark, and transmitting vessels.
• Close-range interactions in areas where AIS data alone falls short.

While Remote Sensing Intelligence does not confirm cargo movement or intent, it reveals the conditions under which anomalous behavior is occurring – conditions that degrade visibility and complicate real-time attribution.

The Combined View Strengthens the Signal

Taken alone, any single anomaly or image could be seen as ambiguous. Together, they provide a more coherent early signal:

• Early Detection pinpoints the where and when of deviation.
• Satellite imagery shows how and under what conditions those deviations are unfolding.

This integrated approach provides stronger confidence that operators are beginning to adapt behaviorally to enforcement pressure, even if the full impact on oil flows is not yet clear.
