Wouldn't ships be able to intercept these?

Lets call the sailors mechanics and the ships frail tech in harsh environment. Suddenly not a good idea.

I would think a ship would have sensors for this sort of thing

A captain told me once that it is silly to assume a big ship dropps it’s anchor accidentally unnoted

Don’t they use something like this on ships to fend off pirates who want to board?

Considering the accuracy of the radar systems (and dozens of millions of dollars spent on them) mounted on a modern frigate or destroyer, a warship crew should REALLY NOT be reliant upon other vessels' AIS to avoid collisions. Warships are maneuverable and fast. Physical failings of the ship aside, I think there's something wrong with the complacency of the crew training.

Removing all of the ports could really be a problem for a ship!

No mention of pirates? Or hackers that can just hijack whole ship.

Considering how long it can take to get the engines started up on a big ship... drifting aimlessly seems a bit risky.

Isn't it because big ships don't maneuver so quickly?
