The North American Oil and Gas industry is an interesting market for any suppliers willing to meet its needs. However, the industry standards are set high and keep evolving. In this regard, this Master’s thesis presents the development of a pedestal prototype, which is the structure linking pipeline process valves to their actuators, in compliance to the industry’s requirements. Thus, this work follows the whole design science research process by drawing up the project specifications as well as designing and evaluating the prototype. Finite element analysis (FEA) and mechanical tests monitored by a digital image correlation (DIC) system were also carried out to complete these steps. Moreover, the gas metal arc welding (GMAW) was the prevalent method chosen to join the structural components of the pedestal. The welding procedure specification (WPS) development and evaluation are therefore covered in this project where five (5) non-destructive testing (NDT) methods were employed. The results suggest that the prototype and its associated WPS meet the standards established by the American Petroleum Institute (API) and the American Welding Society (AWS). Nevertheless, a few elements such as the structure’s fatigue behavior would need to be evaluated in a deeper analysis and only one particular element shall be modified: the tightening torque of the bolts joining the pedestal to the valve.
