It tracks all 55 saturation dive support vessels worldwide on an interactive map, pulling from AIS feeds, satellite detection, vessel registries and industry databases. The map refreshes hourly, so you get a current picture of where the fleet is deployed. (This is open source positioning data - subject to error). Each vessel has a summary of key info covering DP class, sat system config, crane capacity, deck space and draft. There's also a dashboard breaking down the fleet by region, operator and tier. Free to use, no login needed. Built it because I wanted one place to see what's out there without clicking through ten different sites. This was made by Jon McCarty https://dsv-fleet.com/
