| Summary: | `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 |
