Implementing Self-upending for lightweight Jackets in Persian Gulf

S.A. Amid; S. Allahyaribeik

Volume 5, Issue 2 , June 2015, Pages 55-64

Abstract
  Steel-structured jacket or template platforms have been extensively installed in Persian Gulf offshore oil & gas fields. For the jackets in the water depth range of 40 meters in this region, utilizing the self-upending concept has been investigated. It has been concluded that designing the light ...  Read More

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

Abstract
  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

Application of Additive Manufacturing in Marine Industry

A. Ebrahimi
