Computer Aided Design of Semi-Submersibles for Deepwater Operations

Current selection work for offshore floaters typically engaged to detail calculations
and scaled-model testing. Design library for offshore floaters may ease the design
and selection process by providing instant result for basic performance analysis of
the floaters. The project “Computer Aided Design of Semi-submersibles for
Deepwater Operations” is a project made in order to improve the work made in
previous projects on offshore platforms libraries. The main objective of this project is
to improve the variation of the semi-submersibles model platform from previous
project and also to evaluate the performance of the semi-submersible using
parameters chosen. A proper research work has been made before specifying any
design criteria and parameters. The scope of work of the study is to develop the hull
section for semi-submersible model of six-column twin-pontoon. The design of the
floaters and the libraries are developed using CATIA V5R20 with focusing on the
vertical center of gravity and draft of the floater. The performance of the semisubmersibles
is supported using established numerical methods and calculations. The
results are divided to three components of the semi-submersibles floater and its
individual stability analysis. As a conclusion, this project is the improved version of
currently existed offshore floaters design library and may be a stage for any future
library enhancement.
