Last Updated: • Written by Andres Ponce Villamar
Table of Contents
The **MT Rio Napo** is an oil and chemical tanker, identified by IMO number 9256913, that gained international attention due to its involvement in the transportation of sanctioned Iranian crude oil. On December 3, 2024, the United States government officially imposed sanctions on the vessel, designating it as property linked to the India-based entity Vision Ship Management LLP. Prior to these restrictive measures, the tanker was documented transporting approximately 35,000 metric tons of oil-valued at roughly $21.5 million-to the United Arab Emirates, placing it firmly within the complex global network of the "shadow fleet".

Technical Specifications and Classification

The vessel is a mid-sized tanker built in 2003, currently registered under the flag of the Cook Islands. Designed for the efficient transport of hazardous liquid cargoes, its physical dimensions and structural capacity make it a versatile asset in the maritime industry.
  • IMO Number: 9256913
  • Gross Tonnage: 27,829 Tons
  • Deadweight Tonnage (DWT): 47,880 Tons
  • Length Overall: 183 Meters
  • Breadth: 32 Meters
The integration of these technical capabilities with its operational history has made the **MT Rio Napo** a subject of scrutiny for maritime authorities monitoring illicit trade flows. Its classification as an oil and chemical tanker allows it to serve various logistics requirements, though its recent regulatory status has significantly complicated its commercial utility.

Regulatory and Sanctions Context

The geopolitical environment surrounding global energy trade often involves the use of specialized tankers to bypass international restrictions. The **sanctions regime** applied to this vessel highlights the systemic efforts by the United States and international partners to curtail the funding streams associated with unauthorized oil transactions.
  1. Identification of the vessel as a property interest of Vision Ship Management LLP.
  2. Verification of past oil shipments originating from Iranian ports.
  3. Formal designation by U.S. authorities on December 3, 2024.
  4. Ongoing monitoring by maritime intelligence firms to track status changes.
These developments are part of a broader strategy to disrupt the operations of entities like the China Concord Petroleum Company, which has faced multiple rounds of enforcement for its role in managing sanctioned crude shipments. As of May 2026, the vessel remains a point of interest for those tracking the movement of **shadow fleet** assets across the Persian Gulf and surrounding regions.
