Abstract:

:The calculation and analysis of the integral wave load acting on offshore structures is an important step in the design Of the structures. In this paper, a truss-type offshore structure, which consists of cylindrical underwater members with different diameters, orientations and lengths, is taken as the research object, and the wave forces acting on the cylinders are calculated one by one based on the Morison equation and then superimposed to obtain a comprehensive wave load acting on the integral structure. Numerical results show that the integral response of the structure to waves depends mainly on the relative relations between structure dimension and such wave environment parameters as wave height, period and wave direction.

Key words: wave load, truss-type structure, offshore, dynamic response, jacket platform
