Authors: Scott Riccardella and Andy Jensen 2021 marked another successful year for the Structural Integrity (SI) Oil & Gas team with several exciting pipeline integrity projects, industry presentations, training events and research programs. Some of the key highlights include: Continued regulatory consulting support of new pipeline safety regulation (known as Mega-Rule 1 or RIN 1) […]
Structural Integrity’s Own Honored Awarded to an alumnus/a for exceptional accomplishment and leadership in the nominee’s professional or vocational field, which brings distinction to themselves and honor to the university. The contribution(s) need not be publicly renowned but should represent important creative effort or accomplishment with significant impact and value. Barry Gordon is one of […]
PIPELINE INTEGRITY SOLUTIONS By: Scott Riccardella and Roger Royer On October 1, 2019, the Pipeline and Hazardous Materials Safety Administration (PHMSA) published amendments to 49 CFR Parts 191 and 192 in the Federal Register, issuing Part 1 of the Gas Transmission Mega-Rule or “Mega-Rule 1”. In advance of Mega-Rule 1, SI developed field protocol and […]
VESSEL LIFE CYCLE MANAGEMENT By: Erick Ritter and Daniel Peters Initial introduction of many of the hydrogen fueling stations to support this rapidly growing demand were installed around 2010. There were many designs of cylinders developed and installed at that time, many with known limitations on the life of the equipment due to the high pressures […]
FRACTURE TOUGHNESS CRITERIA By: Tim Griesbach and Dan Denis The integrity of the nuclear reactor pressure vessel is critical to plant safety. A failure of the vessel is beyond the design basis. Therefore, the design requirements for vessels have significant margins to prevent brittle or ductile failure under all anticipated operating conditions. The early vessels […]
EQUIPMENT TESTING AND CERTIFICATION TO ASSESS RISK By: Katie Braman Using a risk-based approach derived from various seismic standards from the Institute of Electrical and Electronics Engineers, TRU and BC Hydro will develop a synthetic test motion in three axes, mount the equipment on a triaxial shake table at TRU’s testing partner’s facility, and test […]
ADVANCED STRUCTURAL ANALYSIS By: Livia Mello and Shari Day One of Structural Integrity Associates’ (SI) strengths is combining state-of-the-art software with material science expertise to solve difficult structural and mechanical problems. A notable example in recent years is the Aircraft Impact Analysis (AIA) performed by SI for NuScale Power, using the ANACAP concrete material model. […]
PRCI June Technical Committee Meetings Structural Integrity Associates (SI) recently attended the PRCI June 2021 Technical Committee (TC) Meetings. SI is also planning to support the upcoming PRCI NDE workshop scheduled for October 2021 as well as future committee meetings. SI will continue to engage and support industry with PRCI. As a researcher for PRCI, […]
MATERIALS LABORATORY CASE STUDY 6 THE PROBLEM A supplier of electromagnetic interference (EMI) components noticed that one of their manufacturer’s components was not performing as well as similar components had previously. The supplier had several theories on the make-up of the component and asked SI to investigate and confirm the material constituents as well as […]
MATERIALS LABORATORY CASE STUDY 5 THE PROBLEM A filter was removed from a stator cooling system after pressure differential sensors indicated it may be blocked. The filter was submitted to SI’s Materials Laboratory for analysis to help identify the material blocking it. Figure 1. The filter shown in the as-received condition Figure 2. The yellow […]
