The behaviour of nonlinear irregular waves when interacting with tripile foundations was studied. The analysis was conducted using the open source code HydroDyn. Second-order nonlinear irregular wave behaviour was investigated in terms of surface elevation and wave force acting on the tripile foundation. Calculation was also conducted employing the linear wave theory for comparison purposes. Results show that the linear wave theory tends to underestimate the wave force acting on the tripile foundation by roughly 10%. The second-order nonlinear irregular waves more accurately represent the real ocean environment. A parametric analysis on the effects of incident wave angle on the wave force was carried out. It is suggested that the tripile foundation be installed at an angle of 40º with respect to the predominant incident wave angle.
