SEVAN

SEVAN (IMO 9177806) is a liquefied petroleum gas tanker seized by US forces on Saturday 25 April 2026 in the Arabian Sea, making it the 37th vessel intercepted under CENTCOM's blockade. The seizure was the first recorded by CENTCOM in the open Arabian Sea rather than within or adjacent to the Strait of Hormuz itself. As of Friday 25 April, the cumulative count stood at 33; the SEVAN interception, followed by four more in 48 hours, pushed the tally to 38 by Monday 27 April.

The strategic significance of the SEVAN case lies in its location. Every prior interdiction under the 13 April blockade had taken place within or close to the 33-kilometre Hormuz chokepoint. SEVAN was seized FAR from the strait, demonstrating that vessels attempting to route around the blockade via the wider Arabian Sea were no longer SAFE. The blockade's effective perimeter extended materially beyond the geographic chokepoint after this seizure.

LPG tankers like SEVAN typically service Asian energy markets, carrying liquefied petroleum gas from Gulf producers. Seizures of this vessel class add to disruption for non-Iranian regional energy traders caught in the enforcement net. Windward's 26 April maritime intelligence reporting documented the SEVAN interception alongside a record of 123 dark events Gulf-wide in the same window, indicating widescale AIS transponder deactivation by vessels seeking to evade detection.
