Pacific Ocean

Maritime Risk Briefing · 45 Commercial Ports

Regional Risk Context

The Pacific Ocean basin encompasses the world's largest body of water and hosts some of the busiest commercial shipping routes, connecting the manufacturing economies of East Asia with consumer markets across the Americas and Oceania. The region's ports serve as critical nodes in transpacific supply chains that carry electronics, automobiles, machinery, and raw materials worth trillions of dollars annually. The Pacific's vast distances mean that route optimization and weather routing have significant financial implications.

Typhoon season in the western Pacific (June through November) represents the primary natural hazard. The western Pacific generates more tropical cyclones than any other basin, with an average of 26 named storms per year. Typhoons can produce sustained winds above 150 knots and generate wave heights exceeding 15 meters, posing extreme danger to vessels at sea and causing extended port closures. ArcNautical's stochastic scoring model simulates weather conditions along the planned route using Monte Carlo methods, producing probabilistic ETA and fuel consumption distributions that account for typhoon season routing deviations.

North Korea sanctions enforcement is a significant compliance concern for vessels operating in the western Pacific. UN Security Council resolutions prohibit ship-to-ship transfers of petroleum products, coal, and other commodities to North Korean vessels, and several vessel networks involved in sanctions evasion have been documented operating in the East China Sea and Yellow Sea. ArcNautical screens vessel ownership chains against OFAC SDN, UN Consolidated, and EU sanctions lists, and the AIS anomaly detection system flags potential dark activity.

Port State Control Context

Tokyo MoU

The Tokyo Memorandum of Understanding (Asia-Pacific) maintains the most active publicly-available regional PSC programme. Across the last 24 months, the Tokyo MoU detention dataset records 5,571 distinct vessel detentions (sourced from OpenSanctions, as of 2026-09-27). Vessel-level detention probability is computed by ArcNautical using flag performance, vessel age, deficiency history, and ownership opacity.
