Abstract

This paper is mainly concerned with the investigation of the second order wave loading on offshore structures. The diffraction theory of hydrodynam- ics is used to predict the wave loading. Lighthill's[2] second order theory has been extended to include the investigation to the shallow water case. Wave forces on cylindrical structures are calculated using LighthilPs theory, and the numerical results are compared with the available experimental data. The present theory encompasses the entire spectrum of ocean waves, from deep to shallow water cases, and makes a significant step forward for determining the wave loads on submerged structures. 1 Introduction The problems of hydrodynamic waves and wave loading estimation for off- shore structures have received considerable mathematical and engineering attention due to their many pract
