The photo you saw was taken by an IR/Thermal camera on a rescue helicopter so the "missing plates" you saw on the starboard side was instead hotter plates on the side of the engine room. So no damage i reality on the hull on the starboard side.
I saw video taken by a sailor onboard when she was just listing about 15-20 degrees to portside and then she was still doing speed through the water and engines obviously still working witch supports the theory of a crack on the port side bow of the ship that made her take on water and eventually listing fully and sinking.
