Voyages from Gunsan in South Korea cross the world's largest ocean basin, where route optimisation and weather routing have significant financial implications — a single transpacific crossing can consume hundreds of tonnes of fuel, and a one-knot speed variation over a 12-day voyage materially affects both cost and schedule. The western Pacific generates more tropical cyclones than any other basin (≈26 named storms annually), with typhoon season June–November producing winds above 150 knots and waves exceeding 15 metres. North Korea sanctions enforcement is a significant compliance concern: UN Security Council resolutions prohibit ship-to-ship transfers to DPRK vessels, and dark-activity (AIS disablement) is a common evasion signal in the East China Sea and Yellow Sea.
Routed sea distances from Gunsan to the principal global hubs, computed by ArcNautical's routing engine — around land and through the canals a ship actually uses, not great-circle.
Gunsan falls under the 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 5,577 distinct vessel detentions (sourced from OpenSanctions, as of 2026-10-04). Vessel-level detention probability is computed by ArcNautical using flag performance, vessel age, deficiency history, and ownership opacity.
No port calls were observed at Gunsan between 29 Apr 2026 and 5 Aug 2026. This reflects the reach of the terrestrial AIS network behind this page — coverage is densest in Northwest Europe and thins elsewhere — and is not a statement about traffic at Gunsan. The feed has delivered no positions since 5 Aug 2026, so these figures will not change until it resumes.
