Prediction of Internal Solitary Wave Loads on
 NANHAI 8 Semi-Submersible Platform

doi:10.16183/j.cnki.jsjtu.2019.01.006

Abstract

Abstract: A prediction method is established for internal solitary wave loads on NANHAI 8 semi-submersible platform based on internal solitary wave theory, Morison equation and pressure integral. A series of experiments were carried out to study the internal solitary wave loads in a wave flume. The inertial and drag coefficients in Morison equation for the platform have been determined by experimental results. It shows that the coefficients are not only related to Re number, KC (Keulegan-Carpenter) number and the layer thickness ratio, but also affected by the platform structures. The inertia coefficient decreases with KC number in power function, while the drag coefficient decreases with Re number in exponential function.

Key words: semi-submersible platform, internal solitary wave, model test, inertial coefficient, drag coefficient
