  • RE: How to perform SACS dynamic analysis (Dynpac) with COG shift for topside

    Kasiphon Kurojjanawong
    Kasiphon Kurojjanawong
    COG shift in dynamic run is always an argument from the past until now. Couple forces should not be used in SACS dynamic analysis and also Tow Analysis. The upward forces will be converted to 'Negative Mass' while the downward force will be converted…

    Hi Pei Shing, I understand what you would like to do but unfortunately SACS are not able to print it in this way as we intended to allow user to select the location/fatigue case/side for the output. However I will put your advice to user desired feature…

    Hi Pei Shing, I've tried to open ftgext in precede directly by double click it, and then click report-stress and cycles, the same thing happened. However, if I choose to open a PSVDB database file from a static analysis, and then choose joint - import…

    Hi Actually, I read this long time ago. Then, I just looked in the code again. I also could not found T+0.45Tp in ISO19902. However, this equation is very clear in DNVGL-RP-C203, see picture below. You will found that the equation (5D + 134T) /…

    Hi Pei Shing Ooi As my understanding, option G in FTOPT is applicable for 'Single Skin Grouted' which is the member fully filled with grouted concrete. However, your case is 'Double Skin Grouted' which is one member (pile) inserted inside another…

  • RE: Dynamic Wave Response for Fixed Platform

    Kasiphon Kurojjanawong
    Kasiphon Kurojjanawong
    you are correct. it is typo mistake and i already edited them. If you not call both dynsef and psi during wave response run, fixed boundary will be used during static run to solve applied load from equivalent static load derived from wave response…

    For step 4 wave response 1) Only Wave Response Analysis without Solve (Not required *.CSF) --> CSF is not generated as it is not solved. --> Cannot perform fatigue damage on step 5 -- > No need to call any dynsef or psi. --> You will get only…

    Hi Pei Shing, 1. SLE and DLE are two different considerations which you can refer to design code such as API (chapter 2.3.6.a of API 21st). Generally for area with strength level acceleration less than 0.10g, no ductile level analysis was required…
