how to calculate stability of semi-submersible vessel?

your discuses are useful to me!

 

hi dear
you can model your vessel on Rhino and loft surfases on this,so then save as "igs" format for maxsurf usage.

i can do this for u.send me your cad model,for this.

 

thanks for your interest sir, but i already have the maxsurf model. but the problem occured while calculating the stability, becasue i cant understand which stability criteria in hydromax will be appropreate for such type of vessels.

 

oh ,ok
i can send you the modify MODU code on hydromax criteria,but you may be wait about some day.
at the last night,i had a same project on iranian MODU "shahid rajaee" about the modifing the stability booklet on new inclining experiment.i think you have problems same as i had.

 

first read this file:
OFFSHORE STANDARD
DET NORSKE VERITAS
DNV-OS-C301

 

sir, the problem is, this vessel is not a drilling unit, this is actually multi purpose semi-submersible unit...........can i use the modu code? if so, i already have the GL class codes.

i a have tried to calculate stability with
1.The Health and Safety Executive, Offshore Installations: Guidance on Design, Construction and Certification, Fourth Edition with amendments, 1993.
2.CODE FOR THE CONSTRUCTION AND EQUIPMENT OF MOBILE OFFSHORE DRILLING UNITS, 1989
.......again, if you could please can send me the MODU criteria for hydromax, it will also be very helpful.

thank you very much

 

yes manon,you could use that code.for the semi-sub vessels ,the rules same used for this types.
but on your calculatio,U must be provide the rigging forces on vessel for meassure the righting arm effect,like you calc the wined force and so on.
