Partner ContentHow long does it take for you to receive reports after an inspection has been completed? A week? A month? Does the data come from multiple sources with no way of knowing if it has been manipulated? Traditional inspection contractors do not have the ability to provide reliable and real-time data once an inspection is complete. The only way to ensure accurate, reliable data is with technology.

May/June 2018 Inspectioneering JournalBy Dhananjay H. Rawal at Systech Consultancy ServicesThis article details the experience an oil company had when using FEA to evaluate the implications of a damaged pipeline. Specifically, it presents an efficient method that combines analytical techniques with FEA to determine the pipeline’s fitness for continued service.

May/June 2018 Inspectioneering JournalBy Geoff Clarkson at UTComp, Inc.With no industry consensus documents in existence that provide guidance for determining FFS of FRP, this article provides a case study that illustrates how an existing European design standard on GRP tanks can be used to calculate expected changes in FRP for FRP vessels.
-
March/April 2018 Inspectioneering JournalBy Ibrahim Kodssi at Independent Consultant, and Houssam Sabry at ADNOC LNGImplementing RBI for process piping can be a very tedious and lengthy exercise, especially for major process plants with thousands of feet of interconnected piping. This article shares the experience of ADNOC LNG following a structured RBI approach for piping groups.
-
March/April 2018 Inspectioneering JournalBy Rami Mattar at Amerapex CorporationThis article features a case study on the feasibility of a wall-sticking drone for effectively conducting ultrasonic testing and other NDT methods on equipment at elevated heights.
-
January/February 2018 Inspectioneering JournalBy Phillip E. Prueter at The Equity Engineering Group, Inc.Given the concern throughout industry regarding the potential for brittle fracture failures, PWHT guidance to address potential issues arising from the recent changes in PWHT code requirements for carbon steel is examined in this article, and commentary on the potential reduction in fracture toughness due to PWHT is provided based on a review of published literature.
