Abstract

In this work, the computational fluid dynamics analysis of sections in the circular, square and diamond formats of an offshore platform column was performed, in fixed condition and with two degrees of freedom (2DOF). The simulations were conducted in a two-dimensional laminar ﬂow (Re = 100). The simulations with degree of freedom were performed with a mass ratio of 10, without considering damping. From the results obtained, the lowest mean drag value was found for the fixed circular column and the lowest root mean square lift value occurred for the square section column with 2DOF.
