Well, with what he was talking about, they would have to be electromagnets. In that case, he would be correct. However, I would assume that the other method they would use to lift equipment would also need electricity and be inside the hull of a ship and kept dry, it shouldn't matter which method they use.

Only for wrong meanings of "correct". Electromagnets work fine underwater. The magnetic field doesn't propagate as far as it would in air, same as a permanent magnet.
