Vertical Response of Offshore Structures to Nonlinear Waves-A Review

摘要

The effect of sea severity on the vertical response of structures is reviewed, and it is seen that the vertical responses are consistently smaller in the higher seas than in the lower seas. The application and limits of the Volterra linear and quadratic models are examined. A semi-empirical method like UNIOM is used to overcome some of the limitations of the Volterra model. The Cummins impulse response function determines the lateral and vertical response motion. The developed numerical tool is limited to the slow ship motion.
