We have many options for conducting root cause analyses (RCA) including TapRooT™ and CAST/STPA. The method described here is the method developed by GATE to simplify the analysis while maintaining adequate rigor.

This paper is Part II of a two-part series intended to narrate the history, some of which has been forgotten over time, leading up to the publication of the first Material Requirement (MR-01-75) standard prepared by NACE and its subsequent auxiliary standards.

This is Part I of a two-part series intended to narrate the “lost” history leading up to the publication of the first Material Requirement (MR-01-75) standard prepared by NACE (now AMPP) and its subsequent auxiliary standards.

In recent years, the BSEE Safety Inspection Program section has been developing a risk-based approach to augment these inspections.

The building blocks of a robust inspection program are condition monitoring locations (CMLs). As defined by API 510 and API 570, CMLs are designated locations on pressure vessels or piping systems where periodic external examinations are conducted to assess condition.

Seawater injection is a vital tool for the economic success of some projects and those projects need to ensure that the seawater can be effectively delivered from the seawater source to the reservoir.

This article will outline the challenges during integrity management, and the best practices that ultimately deliver a coordinated, effective, and cost-optimized IM plan.

In determination of consequence and risk assignment, multiple aspects are considered such as the impact of failure on the health and safety of personnel and community in the impacted area, environment, cost of recovery (cleaning, maintenance, extent of operation, repairs) and business.

In this GATEKEEPER, the philosophy around the materials selection and corrosion monitoring is discussed as the primary design barrier to corrosion and cracking in critical parts of a subsea system.

The following material properties are important when understanding the limitations of API 5CT high strength steels: yield strength (YS), Charpy V-notch (CVN) impact energy, hardness and tempering.

An empirical method for improving the predictability of NACE TM0177 Method A Tensile tests on modified 13Cr 110 ksi grade martensitic stainless steels based on an H2S/Chloride/pH function has previously been developed based on published data in order to address this uncertainty.

Casing and tubing that are subjected to combined loads have higher collapse strength than previous formulas would predict, permitting the use of thinner walled, or lower strength, pipe than formerly required.
