There is a simple and quick fix: attack a 2 inch thick steel plate about 4 feet below the hull blocking any RAMMING attempt by the Iranian sub.
The Iranian subs doing this may end up damaged by ramming a turning propellor. Running into a 2 inch (or thicker plate) parallel to the bottom of the tanker suspended by beams 4 feet below the bottom of the ship might do the trick...
I am not an engineer, but at times I appear to have gifted insight...

bring back torpedo nets. USN ships in port are surrounded by a security net, but I think that’s to keep divers away from the hull. Those might not stop a mini-sub.
Wouldn’t that impede the ship’s progress? The push-back and drag of that much water?
Also, to those saying a war with Iran would be horrid. I agree.
The whole nation building thing is highly over-rated. Nation destroying is what would work.
We don’t have to invade. Just destroy their military weaponry (ships, subs, aircraft, radar systems), their port facilities, their oil refineries, oil storage and oilfields and above all, any reactors and centrifuge equipment.
