Join us for our next ACSS New York Chapter webinar, brought to you by the ACSS New York Chapter.

The global shadow fleet has evolved beyond traditional maritime sanctions evasion into a complex geopolitical, security, and financial crime challenge. Recent developments involving vessel seizures, U.S. maritime interdiction and blockade operations, and reports of armed personnel aboard Russian-linked tankers raise important questions about sanctions enforcement effectiveness and the growing risks of confrontation at sea.

This webinar will examine how shadow fleet operators are adapting to increased enforcement pressure, the practical challenges governments face in disrupting illicit oil trade, and the implications for financial institutions, insurers, shipping companies, and sanctions compliance professionals.

The discussion will move beyond traditional sanctions evasion typologies to explore the operational realities of maritime enforcement and the emerging intersection of sanctions, national security, and commercial shipping.

Our Chapter webinars are presented as part of ACSS’s regional engagement initiatives and feature local experts and ACSS community leaders.
