Offshore structures

Offshore platform

I analyze and design offshore structures in my day job, so this collection of articles is my humble attempt at technical writing, and putting theory into practice.

  • Loadout—This article covers introduction to loadout analysis.
  • Tow—This article covers introduction to tow (or transportation) analysis.
  • Installation by lifting—This article covers introduction and analysis procedure to installation by lifting.
  • Jacket float-upend sequence—From either a launch sequence, or lifted-off from a transport barge, the jacket in a horizontal position is sequenced through upending. In pictures.
  • On-bottom stability—This article covers introduction to on-bottom stability analysis.
  • Piling sequence—An intensive, and methodical sequence of driving piles through jacket legs and connecting the shims finally for load transfer from jacket legs to piles. In pictures.
  • Seismic Time-History analysis—This post has a cheat-sheet for a dynamic response analysis, in SACS, using time-history as input.
  • Lifting vessels and barges—A list of lifting vessels and barges operational in the world today.

More to come, hopefully.
