The vast majority of compliance decisions must be made in the blind spot between known information and official sanctions. A vessel may appear “clean” today, passing sanctions screening without immediate alerts, only to be added to a sanctions list weeks later.
This blind spot is where the risk lies.
On April 24, 2026, the U.S. Office of Foreign Assets Control (OFAC) sanctioned 19 oil tankers and liquefied petroleum gas (LPG) carriers linked to illicit trade. These vessels did not suddenly become risks. Before being formally sanctioned, each vessel had already been flagged as high risk in the Seasearcher Advanced Regulatory Compliance (ARC) system, with multiple red-flag indicators pointing to their suspicious activity long before enforcement action.
Why relying solely on sanctions list screening is far from sufficient
If you only rely on traditional screening against public sanctions lists, you capture only a fraction of the overall risk picture. Vessels can use various fraudulent methods to operate covertly until they are formally sanctioned. This lag leaves compliance teams that depend solely on sanctions lists exposed to significant risk.
The good news is: the evidence already exists; you just need to connect the dots.
Risk repeatedly manifests through recurring signals in behavior, identity, and trade activity; integrating these indicators makes it possible to identify fraudulent patterns and fill compliance blind spots.
Fortunately, this is not complicated. We track and pinpoint through automated processes: AIS manipulation: falsified or missing signals to conceal a vessel’s true voyage trajectory. Flag and identity changes: frequent name changes and flag switches intended to disrupt tracking. High-risk cargo patterns: repeated transport of sanctioned goods, often transshipped via complex trade routes.
All sanctioned vessels were already flagged as high risk in advance
Reviewing this OFAC sanctions update clearly shows: all sanctioned vessels had already been flagged as high risk in the Seasearcher system beforehand.
Below, using the vessel LIN 9 as an example, we demonstrate the risk indicators we had identified before it was added to the sanctions list.
LIN 9 (IMO 9240158): Pre-sanctions risk indicator case study
The LPG carrier LIN 9 fully illustrates that behavioral analysis can capture risk signals long before formal sanctions. Since May 2024, the vessel had already shown cargo risk exposure — nearly two years before OFAC sanctioned it on April 24, 2026, under Iran-related programs.
Five Core Indicators: Behavioral Risk (Identity Instability)
Multiple identity changes over six years (previous names: Lotus 6, Coral Alameda, Norgas Alameda), frequent flag changes, consistent with deliberate concealment characteristics.
Five Core Indicators: Voyage Risk (AIS Manipulation)
A total of 3 suspected AIS signal falsification incidents, including an 11-day anomalous voyage record originating from the vicinity of Iran with a clearly abnormal trajectory.
Five Core Indicators: Fraudulent Voyage Behavior
The diagram clearly shows the AIS falsification of LIN 9: a false voyage record lasting 11 consecutive days within Kuwait’s Exclusive Economic Zone, exhibiting a geometrically anomalous trajectory.
Five Core Indicators: Cargo Risk (Sanctioned Trade Exposure)
Since May 2024, completed a total of 16 high-risk LPG cargo shipments, including butane and propane, on routes between Iran and /India.
Five Core Indicators: Comprehensive Risk Profile
Before being formally sanctioned, had triggered 21 sanctions-related risk alerts.
LIN 9 was also included in Lloyd’s List’s LPG Shadow Fleet Watchlist (for ongoing monitoring), but its risk was initially identified through the comprehensive indicators of the Seasearcher Advanced Regulatory Compliance system.
These persistent risk signals indicate that sanctions lists merely confirm risk, rather than triggering it for the first time.
