SACS Post Launch Analysis ( Launch Of Jacket)

SACS Post Launch Analysis ( Launch Of Jacket)

(OP)
Hello Everyone
I wanna perform Static Analysis for a Jacket for tipping position ( Launch of Jacket ) . the Load case has been generated via Post Launch but I don't know which Joints of Launch Truss of Jacket should be restrained for Static Analysis . should I use Springs or just completely fix the Joints ? should I model the Rocker Arm Of Barge ?
my regards ; Ali

RE: SACS Post Launch Analysis ( Launch Of Jacket)

The forces generated should be in equilibrium.Check this in pre vue.
So theoretically,no joints need to be restrained.
For the purpose of analysis, you can restrain any 4 joints with weak spring.
Please check that reactions in these weak springs are really very low.
