It seems that no one at the FCC understands the physics of radiowaves and the effect that they can have on surrounding industry.

It's actually worse than that. The FCC is more likely to require the owners of nearby structures to detune them (at the structure owner's expense) so as not to interfere with the broadcast station's coverage. (Assuming this is an AM broadcast station.)

It's a common problem, signals are induced into water towers, cellphone towers, high voltage power lines supporting structures, etc. and this can be a problem at some distance (I've seen structures requiring detuning a mile or more from the AM station tower.)

The usual solution is to add detuning skirts to the re-radiating structure, so as to make it "invisible" to the AM radio signals. That's not so easy to do if the re-radiating structures are moving or change their height.

That’s exactly what they are fighting about now, but since the cranes are on ships, it would require all ships coming into that port to have some kind of protection. Or, maybe just have the refinery buy their own crane and use that, instead of the ship’s crane.

The ship’s crane was running enough voltage to fry the meter that was left on it.
