This paper discusses the model test results of float-over barge used for
the installation of topsides onto jacket platform, which were carried out
in the shallow wave basin of Universiti Teknologi PETRONAS. The
objective of the paper is to highlight the importance of determining the
single barge responses prior to performing multi-body dynamic analysis
of float-over installations. As part of developing the industrial
capability of model testing in this wave basin as an indispensable
component of the design of float-over barge, the methodologies and
procedures for test setup, execution and analysis are described in this
paper. Furthermore, the method of data analysis using advanced
numerical method for regular wave named Filon Quadrature method
are discussed and the test results are presented in terms of first order
responses, namely RAOs of the barge for head and beam seas. Results
of the model tests were cross-checked with the results of established
diffraction method using 'WAMIT' and were found to be generally in
good agreement for predicting the dynamic responses of float-over
barge subjected to waves.
KEY WORDS: Float-over barge; first order responses; model tests;
diffraction method.
