Structural analysis of offshore module

Abstract

The thesis will contain analyses of an existing platform consisting of five decks, including a cellar deck. The platform has already been completed, and the objective of the thesis is to look into if there are alternative actions in order to suggest a better suited placement of the platforms bridge landing. The platform will be exposed to a set of defined loads: Environmental loads, dead loads and live loads. With the new placement of the bridge landing, the utilization of the girders will be checked. In order to prove the improvements, selected elements of the structure will be controlled. StaadPro 2007 is used for modeling and conducting analyses of the structure. The structure is checked for ultimate- and serviceability limit states according to the requirements of the NORSOK standards. The conclusion shows that another location for the bridge landing can be considered, depending on the assumptions made.
