Caribbean Sea · Multi-Purpose Port
In the last 180 days, ArcNautical recorded 291 vessel arrivals at Houston, with Unknown accounting for 28% of port calls — higher than the Caribbean Sea regional average of 22%. 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.
Across 291 distinct vessel arrivals, 279 carry a confirmed AIS ship-type code. The most common categories at Houston:
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.
