Design of Offshore jacket platform
Design of Offshore jacket platform
(OP)
In design of Offshore jacket platform, I am having wave & current loads and ship impact load as lateral loads. Fr analysis purpose there are two types one is linear static analysis without effect of ship impact and another is ship impact analysis (nonlinear static pushover) without wave loads. If I m doing linear static then the structure is overdesigned in UC check. But for ship impact nonlinear static analysis the structure doesn't meet the requirements. If anyone have knowledge about this then please help me out with this.
Thanks
Thanks






RE: Design of Offshore jacket platform
I noticed that you said you were performing a pushover analysis. Are you actually incrementing a load or are you performing a nonlinear analysis which stops at the desired energy level. I am a SACS user and I know that SACS calls all nonlinear analyses "pushover analyses" in the analysis type selector. You can also use the ship impact analysis specifically designed to perform nonlinear dynamic ship impact analyses.
RE: Design of Offshore jacket platform
What I understood is that I have to design the structure for only one lateral load i.e. ship impact load. Other loads will be taken care off as ship impact will be always higher than other lateral loads eg. wave and current loads. This was the ans from one of the source that I got. Is it true?
