Estimated
Caesar II has the capacity or forms of calculating buoyancy
Thank's

If you're asking if CAESAR II can calculate buoyancy, the answer is "yes". Buoyancy is automatically considered in the "weight vector" anytime WAVx is included in "any" load case.

We have a pipeline buried in an area with water level hight (groundwater), and we need check if exist bouyancy problem.
how to entry input in to the caesar II to modeling this soil or load case. Tipicaly.

Ok, CAESAR II can't do this. Either the pipe is buried, submerged, or above ground. These are exclusive traits.

so does that mean that if the wave loader is turned on if i am entering rigid weights (valves etC) i can enter the 'in air' weight and the bouyancy will be calculated within caesar?

Yes, that is correct.

Good Afternoon, if I found the Buoyancy load (distributed load)on my buried pipe system, Can I simulate this load in the Caesar II like a Uniform load? or it will be a mistake.

Yes you can do this, BUT, if the pipe is submerged, and you include WAVx anywhere in any load case, CAESAR II will compute and apply the buoyancy load. Be careful you don't "double-dip".

Hi
It seems that one of my problem regarding subsea buoyancy analysis is solved by reading this thread, but i have another issue that I want to ask...
My project involves a subsea structure (PLET - pipeline end termination) in which the pipe is located 1350 m in depth. The problem occurs when i tried to do the analysis. It seems like because of the depth, my system is outside the applicable "wave theory" region
Could you please advice regarding on this matter
Regards, FaizAriff

Check the wave solution to make sure it converged. If not, tweak something, perhaps change the wave theory.

I'm aware of the wave theory, the problem is due to my depth, there is no wave theory suitable for my analysis
Is it okay if i assume that due to the depth, there is no wave calculation involved? only current is applied to the analysis?

Then this is a discussion you need to have with the Client/Owner ...
