Recent Port Calls (AIS)
No AIS port-call data captured for SIREN II in the last 180 days. Sanctioned vessels frequently transmit AIS irregularly or disable transponders entirely — this absence is itself a vetting signal documented in the OFAC, EU, and IMO sanctions evasion advisories.
Flag State Risk Analysis: China
SIREN II is flagged to China, which holds White List (low risk) placement under both the Paris MOU (White List, 1.2% detention rate) and Tokyo MOU (White List, 0.4% detention rate) port state control regimes. White list flags demonstrate consistently low detention rates and strong compliance with international maritime safety standards, indicating that the flag state's maritime administration maintains effective oversight of its registered fleet.
While a white list flag is a positive indicator in vessel vetting, it does not eliminate compliance risk. Vessels flagged to well-regarded registries can still be subject to sanctions, operated by opaque corporate structures, or involved in illicit activities. ArcNautical's comprehensive screening evaluates sanctions status across OFAC SDN, EU, and UN databases, ownership transparency through GLEIF corporate chain analysis, and historical PSC detention records to provide a complete risk picture regardless of flag state reputation.
