WAVE RUN-UP SIMULATIONS AND COMPARISON WITH EXPERIMENTAL DATA ON A SEMISUBMERSIBLE
Abstract
Use of CFD tools for industrial offshore applications is a great interest nowadays, therefore is the need for validation of such tools against experimental results. This paper presents wave run up estimations with a fixed large volume semi-submersible performed with the CFD code ComFlow. The predicted results of numerical simulations are compared with experimental data at two locations: on the first and the second column of the semi-submersible. These codes are used to simulate the flow around a semisubmersible offshore structure due to an incoming regular wave under the influence of high steepness regular waves. Wave basin tests were performed with small scale model of a large volume semi-submersible. These tests evidenced some issues of the run-up effects along a semi-submersible body and it will be shown that the simulation results are quite similar with the experimental data.
