Description:
Maritime sanctions enforcement is no longer about delayed OFAC penalties — it is now a world of real-time vessel designations, Department Of Justice (DOJ) indictments, asset forfeitures, and cross-border litigation.
This session will unpack how enforcement has evolved, drawing on real-world examples including a case where a shipowner faced vessel arrest attempts and conflicting legal rulings despite doing everything right.
We’ll also explore the growing trend of SDNs filing lawsuits, the challenge of invoking sanctions clauses, and how due diligence failures can now lead to reputational and legal ruin.
Whether you are in compliance, legal, chartering, or trade finance, this webinar offers timely insights into how to protect your business in a high-stakes environment.
What the webinar aims to cover:
-
How U.S. enforcement has shifted from civil penalties to criminal prosecution and cargo seizure
-
The impact of real-time vessel designations and DOJ-led forfeiture actions
-
A case study breakdown of a charter gone wrong — and its global legal fallout
-
Why SDNs are suing vessel owners, counterparties, and insurers — and sometimes with favorable results
-
Risks in sanctions clauses and due diligence gaps that are triggering lawsuits
-
Actionable steps for compliance, legal, and operational teams to stay protected
