abstract: A Large-eddy Simulation (LES) has been conducted of the flow around typical oil-production jacket platform in a sea of relatively shallow water depth. The LES solves for a three-dimensional flow with moving free surface using appropriate sub-grid turbulence and wall models. The structure consists of various slender tubular members in truss configuration. It is assumed rigid and the pressure distribution obtained by the LES is integrated over individual members and over the entire structure to evaluate the loads. The flow approaching the jacket platform is assumed known but is possible to be obtained from the larger-scale simulation reflecting the details of the bathymetry of the surrounding sea bed and the metocean conditions. Although the results need to be examined in detail and cases with different current speed, direction and wave heights but the present results are reasonable and promising first step for further calculation.. © 2019, IAHR.
