ABSTRACT
Background The efficiency and safe design of marine platforms depend on a complex structure of mutual influence between these facilities and the surrounding environment and the degree of resistance to different loading patterns during the entire investment period. Fixed jacket platforms are huge steel framed structures used for the exploration and extraction of oil and gas from the earth’s crust. Jacket type structures are appropriate for relatively shallow water depth. Objectives: the objective of this study is to select specific parameters for the elements of a fixed platform (jacket) and conduct an static analysis study to resist these elements for the influence of the basic loads that are subject to it within the environment of the Syrian coast , using the software SACS. Methods: the jacket is modeled in SACS finite element program and static analysis is conducted with fixed boundary conditions. Critical conditions are taken into account, which include structure and equipment weight, wind load, hydrodynamic load using Morison equation. Results: Linear static analysis is performed for the four legged jacket considering (3) loading directions. The maximum base shear and overturning moment are calculated in normal environmental conditions and stormy. as well as the unit check values, for all member are obtained it. Conclusions: the environmental conditions of the Syrian coast are suitable for the construction of jacket offshore, therefore a great importance to support the Syrian national economy.
Keywords: Unity Check, Jacket, Linear Static Analysis, SACS software.
