Global Shipyard Visits & Repair Intelligence
Track over 120,471 vessel visits across 1,117 shipyards worldwide. Discover which vessels are under repair, analyze drydocking durations, and monitor global shipyard utilization.
How we calculate Shipyard Visits
Our database is powered by high-precision geospatial tracking and advanced algorithms that transform raw AIS data into actionable maritime intelligence.
Geofenced Polygon Detection
We maintain highly accurate, hand-drawn geofenced polygons around thousands of shipyard facilities worldwide. When a vessel enters these predefined areas, an arrival event is automatically triggered and recorded.
Duration & Status Tracking
Once inside the yard, the vessel's continuous presence is monitored. We calculate the exact duration of the stay in hours, identifying whether a vessel is actively undergoing repairs, laid up, or drydocked.
Drydock Classification
By cross-referencing precise vessel coordinates with specific drydock basin polygons within the shipyard, we can differentiate between afloat repairs and actual drydocking events.
