Recent Port Calls (AIS)

Flag State Risk Analysis
The flag state for DIAMOND II is not currently recorded in public sanctions databases. Flag state identification is a critical element of maritime due diligence, as it determines the regulatory framework governing the vessel's operations, the port state control inspection regime it faces, and the extent to which it may be subject to sanctions enforcement by various jurisdictions. ArcNautical's live screening tool checks the vessel against OFAC SDN, EU, and UN sanctions databases regardless of flag state availability.
Vessels with unknown or undisclosed flag states warrant additional scrutiny in compliance assessments. The absence of flag state data may indicate recent reflagging, administrative gaps in registry reporting, or deliberate obfuscation. ArcNautical's ownership opacity scoring evaluates corporate transparency through GLEIF registry data and beneficial ownership chain analysis, providing an additional layer of risk assessment independent of flag state information.
