Description
Book SynopsisSponsored by the Ocean and Offshore Engineering Committee of the Coasts, Oceans, Ports, and Rivers Institute of ASCE. Spar Platforms: Technology and Analysis Methodsexamines the design, analysis, and use of spar platforms for offshore oil production. Since the first spar platform, the Oryx Neptune, was installed in the Gulf of Mexico in 1996, spars have evolved into a proven, reliable technology for oil drilling and production in deep and remote areas. Three spar concepts are in use today: the classic spar, the truss spar, and the cell spar. Although the technology and analysis methods are considered mature, technical challenges remain, including understanding and suppressing vortex-induced motion and improving survivability in category 4 and 5 hurricanes. This volume surveys the history of spar development and presents detailed design modeling aspects of spar hull, mooring, and anchoring systems. Two methodologiesthe diffraction method and the Morrison formulathat can be used to
