That’s just the beach side “dock”. There’s an unconnected pier somewhat further out in the water, where the depth allows large cargo ships. Those large ships unload onto the pier, then smaller ships transport the goodies to the “dock”.
(I’m likely using the wrong terminology.)
The You Tuber “What’s Going On With Shipping” explained it a lot better, then pointed out the inefficiency and asked why not just bring the goods in via an existing Israeli port, then truck it to Gaza. And here we are!
