Abstract

`Hydrodynamics Stability of a Semi-submersible Offshore Platform'. This project is basically will prove on the reliability of design in theory by performing experiment on the scaled model. The experimental are run to provide reliable experimental data for responses of semi-submersible offshore platform and to verify and compare the results with the literature (hypothetical data) on the hydrodynamics stability. The idea of the project was based on the comprehensive design from University of Texas on the "Conceptual Design of a Semi-submersible Floating Oil and Gas Production System for Offshore Malaysia". A semi-submersible platform connected to the sea bottom by anchoring the mooring lines that is functioned to ensure that the platform will maintain on site during operation. Starting with few researches on relevant information of semi-submersible and related floating structures overview; the mathematical calculations is done to analyze the stability of wave impact and the balancing of the substructure weight that will enable the superstructure to float on the water surface. Modelling comes after the entire theoretical part is covered. The fabrication of a scaled model (1: 100) of the semi-submersible platform was built in order to compare the experimental hydrodynamics data with the actual performance data to ensure better understanding and clarity of this study. Total number of eight experiments are carried out consist of variation in value of wave height; 0.10 in and 0.20 m; wave period, 2.0 sec and 5.0 sec; and current velocity; 0 m/s and 0.20 m/s. During data gathering and analysis, correction factor is applied to generate the accurate values
