Abstract

The goal of this thesis is to perform a global structural analysis of the deck truss structure of a semi-submersible Floating Production Unit (FPU). The primary objective of this structural analysis is to verify the global strength of the deck truss structure, ensuring its compliance with the American Bureau of Shipping (ABS) rules for building and classifying Floating Production Installations (FPI). Semi-submersible FPUs are vital in offshore oil and gas production, providing a stable platform for drilling, production, and processing operations in deepwater environments. The deck truss structure is a critical component, supporting the topside facilities and ensuring the overall stability and integrity of the unit. The research involves developing a detailed finite element model (FEM) of the deck truss structure, incorporating material properties, geometric configuration s, and boundary conditions. The model is used to simulate various loading scenarios, including environmental loads, as well as operational loads from equipment and personnel. The analysis aims to identify critical stress points and potential failure modes, ensuring that the deck truss structure meets the required global strength criteria as specified by ABS standards.
