Abstract: Although novel techniques and high performance material open the way for generation of high-performance welded joints, the welding operations are inherently quite complex and expensive. This has been the case, especially ...

Abstract: Vibration induced fatigue (VIF) failure of topside piping is one of the most common causes of the hydrocarbon release on offshore oil and gas platforms operating in the North Sea region. An effective inspection plan for ...

Abstract: This paper examines the applicability of the different surrogate-models (SMs) to predict the stress intensity factor (SIF) of a crack propagating in topside piping, as an inexpensive alternative to the finite element methods ...

Abstract: Technology qualification (TQ) centers on establishing an acceptable level of confidence in innovative aspects of new technologies that are not addressed by the normative standards and/or common certification procedures. ...

Abstract: Currently, in the oil and gas industry, finite element method (FEM)-based commercial software (such as ANSYS and abaqus) is commonly employed for determining the stress intensity factor (SIF). In their earlier work, the ...

Abstract: Underwater friction stud welding (FRSW) without a shroud around the stud requires controlling welding parameters to achieve optimal joint strength. A hydraulic FRSW unit has been designed and fabricated to perform FRSW ...
