A barge carrying 700 Tons of added weight (7 motors) plus its own weight is to be anchored using driven steel pipes (piles), (48” diameter, 5/16” thick) that run 34 meters deep into the sea bed. The barge is to have free vertical movement while its lateral movement is to be transferred to the pile cap through bumpers, so it seems that only lateral loading of the piles would be important to consider.
The geotechnical report states that the allowable lateral load for the piles is 10 Tons.
I really need some guidance, since most of my experience is based on designing building structures. Some of the questions that come to mind are the following:
1)What lateral loads to consider. Certainly Seismic loads, but what type of structure would it be? Should I treat it as a cantilever structure? While considering loads related to the tide, is there a way to consider or estimate the lateral load as a percentage of the load supported by the barge and the weight of the barge itself?
2) What detailing goes into achieving that fact that the piles would permit the barge to freely move vertically while restraining it laterally? Should there be a fixed connection that the pile head? Is there a special detail of the piles at the sea bed?
3)Any other thing that I might be missing.
Thanks for your time.
