\"\"\n\n\n

When the signal stops, the intelligence stops.<\/h2>\n<\/div>\n\n\n
<\/div>\n\n\n
\n

Dark vessels are ships that have deliberately disabled their AIS transponders to avoid detection. AIS is the cooperative signal conventional monitoring depends on. When a vessel turns it off, it disappears from AIS-only platforms.<\/p>\n\n\n\n

Sanctioned vessels go dark to evade enforcement; smugglers to avoid interception; illegal fishing fleets to operate in protected waters. State-sponsored dark fleets have expanded dramatically, driven by sanctions on Russian, Iranian, and Venezuelan oil: a parallel shipping infrastructure operating almost entirely outside conventional monitoring.<\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n

SAR Detection<\/h3>\n\n\n\n

Synthetic aperture radar scans ocean areas and identifies vessel-sized objects regardless of weather, time of day, or transponder status, with no emitted signal required.<\/p>\n<\/div>\n\n\n\n

Satellite-detected vessels are cross-referenced against known AIS positions. Detected by satellite but not broadcasting is flagged as dark.<\/p>\n<\/div>\n\n\n\n

Shadow Fleet Tracking<\/p>\n<\/div>\n\n\n\n

A parallel system, tracked continuously.<\/h2>\n\n\n\n
\n

Since 2022, sanctions on Russian crude have driven the formation of a parallel shipping infrastructure: hundreds of aging tankers operating under opaque ownership, frequently disabling AIS during sanctioned voyages.<\/p>\n\n\n\n

Theia tracks shadow fleet activity continuously: the vessels, the routes, the ship-to-ship transfer hotspots, and the ownership patterns that define this parallel system. For governments enforcing sanctions, insurers assessing exposure, and traders verifying cargo origin, shadow fleet visibility has moved from useful to essential.<\/p>\n<\/div>\n<\/div>\n<\/section>\n\n\n\n
