Numerical Study of Current Forces Acting on Floating Bodies in Side-by-Side Configuration

Abstract

In this study, the characteristics of current forces acting on four floating bodies are numerically investigated by using a commercial CFD software, STAR-CCM+. In the numerical analyses, 170k LNGC is located Left of FLBT and 30k & 5k LNG Bunkering Vessels are located right of FLBT under the uniform current conditions. Steady calculations with Reynolds Averaged Navier-Stokes(RANS) solver and realized k-epsilon model were conducted. Firstly, current coefficients of FLBT by CFD. Using the same technique, computation was carried out on the current loads of FLBT and 170k LNGC, 30k & 5k LBS in the side by side arrangement. In addition, the relative distance of 5k LBS that berth was independently changed to examine the current load property of 5k LBS and FLBT.
