I think that’s a pix of one of the little service boats, not the main pier.
The “little service boats is a WWII style LCM (Landing Craft Mechanical (for tanks, trucks, bulldozers, cranes, tow trucks, graders and general vehicles and cargo).
Yes, it and the pier section were blown away from the longer, larger main pier and onto a nearby beach. Once drifted and swamped sideways like that, it is “very hard” to recover the craft undamaged and safe for future ops.
In WWII, a swamped LCM was basically abandoned, since there so many. Now, with a a few dozen in the entire Med, it has to be retrieved and repaired
At a few millions more wasted effort.
