This  thesis  emphasizes  one  practical  offshore aspect and optimal cost consideration. Two  models,  namely  Gravity-based  minimum  unmanned  stacked  platform  and  Piled  minimum  unmanned  stacked  template  platform,  are  proposed  after  reviewing  the  existing  minimum offshore structure design concepts around the world.  The design and analysis of total six models were carried out by performing dynamic wave in-place analysis to verify the structural strength and serviceability of these platforms for designed water depth of 40 m,  60  m  and  80  m,  subject  to  two  storm  cases  1-year  and  50-year  storm  environment.  These  two  storm  cases  are  taken  as  design  criteria  for  platform  operating  and  extreme  storm conditions respectively.  The  results  show  that  these  two  minimum  platform  configurations  are  practically  self-installable  for  marginal  fields  in  the  GOT  by  using  tandem  barge  with  topside  crane  pedestal.  No  jack-up  rig  assisted  installation  scheme  is  selected  in  order  to  provide  installation schedule flexibility. 0aOffshore structureszThailand, Gulf of1 aChiu, Gregory L.F.,eChairperson1 aWidjaja, Joko Harsono,eCo-Chairperson1 aWang, Ching-Jong,eExamination committee 2 aRoyal Thai Government Fellowship,eScholarship donor2 aAsian Institute of Technology.tThesis ;vno.
