Numerical modeling of wave run-up along columns of semi-submersible platforms

SH. Entezam; S. Kazemi

Volume 5, Issue 2 , June 2015, Pages 77-86

  Wave run-up is one of the most important and effective parameters in designing semi-submersible platforms. Besides unforeseen effects on the movements and response of the platform, wave run up can also cause slamming forces to be exerted on the lower deck of the platform. Therefore, at the first stages ...  Read More
