Severe dock damage from hurricane

[Jerseydave]

Hi all,

Our group property just experienced very heavy dock damage from flooding 2 days ago. Our main dock is perpendicular to the shoreline, with a walking dock parallel to the shoreline and 2 more fingers extend out from that. When floodwater and strong currents occur it’s just too much for it.
I’m open to a better design so any of you engineers can make suggestions.
We would also welcome some type of quick release method so we can pull the docks before major storms. (Something like group did not do this time but we should have)
Now we need to hire a crane to get the dock back in the water for dis-assembly and make major repairs

Yikes! Sorry to hear that Dave

Wow - for sorry this happened!

That sucks. Sorry to hear.
For round two, can you put a heavy galv cable at angle from point near end of dock back to shore? Primarily up river (you said current, assume you are on a river?).

Or wheels to quick attach to the shore end so you can pull it in with tractor or vehicle.

We had at least 3 heavy cables attached to trees upstream. We assume floating debris hit the dock and pulled the cables right out of their clamps.

This river is relentless. This storm raised the river over 12 feet above normal height!
I think we need the dock to have a 45degree angle on the upstream side, with the rest of it parallel to the shoreline. (Picture the shape of a roof truss laying on its side)
Then also a fast way to disconnect it. Our pin system should work for that

My engineering manager has a dock on the Mississippi river. He used I beams that pin to the dock and shore. He pulls his out every winter to save it from damage at ice break up time.

Speaking from experience get ahold of a dock builder ASAP. Assuming your not going to it yourself. Storm dock damage like this hits Florida it can be years before they can get to you....it was 18 months before my builder could get onsite.

In other big river areas that I've seen the common way is to put 2 poles with collars for the dock to come up - they have to be high enough to keep the dock located at peak flood height called pipe piles.

My other buddy that builds a lot of docks on the Mississippi just drops a couple of giant metal beams down into the ground and lets the dock float up and down on them. They use ratchet straps to pull them up when they need to move them.
