GPS-jamming caused 4 near-collisions in Gulf of Finland last year. Ships made it because Finnish coast guard intervened.
The cause seem to be both external (the St Petersburg jammer et al) and endogenous (ships manipulating their own AIS)
It is general consensus that oil tanker collisions are bad.

The Russian shadow fleet is not only cutting undersea cables in the Baltic Sea but also poses a significant environmental and navigational threat due to the combination of GPS jamming and manipulation of the fleet’s ships’ locations. The Finnish coast guard prevented 4 accidents this fall

Russia is running GPS-jamming machines in St Petersburg and Kaliningrad, affecting aviation and sometimes shipping around Baltic Sea.
Some of my most appreciated work has been localizing these machines in time, space and volume.
Here's a rundown of previous geo-work, reversed chronological order.

The Kaliningrad GPS/GNSS jammer is running on low power last two weeks, back to summer levels after a month at higher output.
The jammer in St Petersburg, covering Finland and Estonia might be tuned down a bit, but less clear trend.
