14 Some challenges during launch and upending Position and size of temporary buoyancy tanks Maximum forces at rocker beam Maximum depth during launch Structural loads due to hydrostatic pressure Bottom clearance Floating condition after launch Access to lifting arrangement Upending Structural loads Crane load Bottom clearances Proper upright position Ballasting of side legs

15 Jacket installation: crane lift

16 Jacket installation,- final phases Jacket in upright position? Ballast in jacket legs Transit to set-down point. Several 100 meters Further ballasting and lowering by crane Landing Release crane On-bottom stability in temporary phase? Piling
