None of the 318 vessels our AIS feed observed within 25 nm of Houston between 29 Apr 2026 and 5 Aug 2026 broadcast an IMO number on the OFAC, EU, UK or UN sanctions list today. The feed saw only part of the traffic, so this does not mean no listed vessel called here. The feed has delivered no positions since 5 Aug 2026, so these figures will not change until it resumes.

Between 29 Apr 2026 and 5 Aug 2026, ArcNautical's AIS feed observed 318 distinct vessels at Houston, with Towing making up 28% of those with a ship-type code — in line with the Caribbean Sea regional average of 23%. Houston in USA operates within a strategic crossroads connecting North and South American trade with the Panama Canal, Gulf of Mexico energy complex, and transatlantic routes. Hurricane season (June 1 – November 30) is the dominant natural hazard; category 4 and 5 systems generate winds above 130 knots and storm surges that devastate port infrastructure. Track forecasting has improved, but rapid intensification remains difficult to predict beyond 48–72 hours. Venezuela sanctions represent a significant compliance challenge for any vessel operating in the basin — the US has maintained comprehensive sanctions against Venezuela's oil sector since 2019, and the framework is modified frequently through general and specific licenses. Vessels with prior Venezuelan port calls face enhanced OFAC scrutiny.

Houston falls under the US Coast Guard. The US Coast Guard operates its own Port State Control programme rather than participating in a regional MoU. The USCG Port State Control Annual Report publishes detention statistics by flag and class society. ArcNautical evaluates per-vessel detention probability using flag performance (USCG QUALSHIP 21 status where applicable), vessel age, deficiency history, and ownership opacity.
