Sanctions Pressure
How the designated fleet grew month by month, how much of it we track, and where ships were observed alongside each other offshore.
The designated fleet, over time
Every hull carrying an official designation, accumulated month by month, with the share that sits in the fleet we track shown separately, so the coverage gap is visible rather than implied.
1,907 hulls carry a designation today, of which 963 are in the fleet we track. The past twelve months added 398. Pressure is easing.
A hull listed by several authorities is counted once in each, so the authority figures do not sum to the total. A further 99 listed hulls carry no published designation date and cannot be placed on this timeline. 1,565 sanctioned companies are also tracked; the company side publishes no listing dates, so it is a current count rather than a history.
Where ships met at sea
Vessels observed close, slow and offshore for hours at a time. Marker size and colour carry how strong the observation is: proximity, how long they stayed, and how far from port. These are candidates, not confirmations: an anchorage can produce the same signature, and we say so rather than dressing an observation up as a finding.
