CFD assessment of the wind loads on an LNG carrier and floating platform models

Numerical analysis of the wind forces acting on a floating LNG platform and an LNG carrier models is performed with a computational fluid dynamics (CFD) code and compared with experimental results obtained in a wind tunnel. The results are represented in the form of coefficients of the wind force components in X and Y directions and yaw moment for various angles of wind attack. The numerical study based on a CFD code started by performing several tests with different type and resolution of the mesh. The results were also compared with two empirical methods as well as additional experimental measurements of similar LNG carrier. Reasonable agreement of the numerical and experimental results was reached.
