Abstract:
The objective of this project is to study the behaviour and performance of an innotative floating offshore platform. Such Platform not only can be used for exploring oil from offshore fields, but for creating artificial islands, where land is in short supply. Due to its specific and, at the same time, simple geometry (symmetric), its fabrication does ont involve much complexity. Studies carried out on this platform include the investigation into its structural behaviour under gravitational (including self weight) and bouyancy forces. Studied cases include a number of platforms with different (geometrical) sizes and under 3 various bouyancy conditions (percentage), namely 1) 50% of the height of the platform is submerged, 2) 75% of the height of the platform is submerged, and 3) 100% of the height of the platform is submerged. These studies showed that the level of stresses as well as displacements in various parts of the platfroms were far below their allowable thresholds. This took place despite the very low relative thicknesses of the studied platforms
