Instability analysis of deepwater riser with fairings

Characterization of the Thermophysical Properties of Riser Sleeve Materials and Analysis of Riser Sleeve Performance

Riser sleeves are an effective tool in the steel foundry industry for minimizing riser size and increasing casting yield. Reliable simulation of the performance of riser sleeves requires accurate temperature dependent thermophysical properties. Unfortunately there is little or no such property data available in the open literature. A limited number of sleeve manufacturers provide advice and pro...

Spatial analysis of instability intensity of the villages with sustainable approach in Kaki district, Dashti Township

Sustainable development is an environmental concept appropriate to our era that nowadays in all of economic, social, environmental and physical-‌spatial aspects is considered and focused by everyone. In these times, global organizations that are working around the issues of sustainable development, emphasis on rural sustainable development, which seeks to improve rural living standards and welf...

Finite Element Instability Analysis of the Steel Joist of Continuous Composite Beams with Flexible Shear Connectors

Composite steel/concrete beams may buckle in hogging bending regions. As the top flange of I-beam in that arrangement is restricted from any translational deformation and twist, the web will distort during buckling presenting a phenomenon often described as restricted distortional buckling. There are limited studies available in the literature of restricted distortional buckling of composite st...

Transverse Vibration Analysis of the Riser in Deep Water

With high international oil price, the exhaustion of onshore resources and declination of oil and gas production in shallow sea, deep water has become the important succeeding area of worldwide oil and gas. During deepwater oil and gas development, riser must be used to isolate seawater, circulate drilling fluid, and compensate the heaving movements of the string and so on. However, with the op...
