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 weight jackets, implementing the self-upending process for their installation operations, are econom...

A 57-year-old male visited our clinic with chief complaint of exertional chest pain. He had been on anti-hypertensive medication for 15 years. In 1999, he went through coronary artery bypass graft surgery for myocardial infarction, using an aorto-left anterior descending artery (LAD) bypass with the left internal mammary artery, and aorto-right coronary artery (RCA) bypass with saphenous vein. ...

In offshore structures, most of failures are caused by the lack of sufficient piles strength. Scour phenomena affects the load transition and the pile strength. The necessity of the consideration of scouring phenomena amplifies when the scour depth becomes remarkable, which can endanger the jacket stability. In this paper, a new method is used to consider the pile scouring using nonlinear pusho...
