Variation of stress created by waves and marine currents in a leg of offshore platform

The offshore platform have usually leg for sustaining on sea deep. The calculus of the legs is very complicated because of the variation of the loads in time. In this paper is present the numerical results for charging of a leg with forces caused by waves and marine currents. The software for calculation of force induced by water use Airy theory (for regular waves). The structure has been analyzed numerically using the program Solid Works-COSMOS/M (stress and displacements), and FORHID (loads).
