Recent studies show that the Hydrotesting as the most common method employed for the pipeline integrity may cause damages to the structure, however, it might also improve some mechanical properties of the pipelines. Due to the growing use of hydrotesting of the pipelines in oil and gas industries, the first part of the project was therefore devoted to studying standards and procedures of this technique in order to provide all technical requirements and optimized instructions. Furthermore, at the second part of the project, a new emerging technique so-called Long Range Ultrasonic Testing (LRUT) was designed, developed and implemented in order to replace the traditional Hydrostatic testing. This reliable and cost-effective technique takes advantage of guided waves to inspect and screen pipelines for damages at the long distances in a pulse-echo configuration mode.
