Material used in geothermal power plant components can experience damage during direct contact to geothermal steam. This applies specifically to turbines components as they can be prone to erosion and erosion-corrosion due to droplet formation and corrosive species present in the steam. Development of coating material as protection against such damage is being investigated. To test such effects on coatings a device was developed for in-situ testing in geothermal fluid. This device is capable of creating an erosive environment from geothermal fluid through pressure drop created by an orifice. The corrosive species present in the fluid then subsequently lead to the creation of an erosive-corrosive environment. This paper describes the development of the test setup and its potential for creating an adequate environment to test erosion-corrosion experienced by geothermal turbine components. The final setup allows for simultaneous testing of six samples. The variance between the locations of the sample holders in the device was analysed to determine its effect on results for the tested coated samples. This device was used to test different types of coatings among which electric arc sprayed titanium coatings were tested. They were located in different sample holders and their results compared in light of the differences between the environments present in the holders.

Inspection & Corrosion Control of Wet Sour Gas Subsea Pipelines

Product Number: MPWT19-15277

Author: Meshary A. Al-Bahli, Rashed Alhajri

Publication Date: 2019

$0.00

Recently the oil, gas and petrochemical sectors have been facing together safety, environmental and mechanical integrity regulations as well as challenges associated with the need for cost reduction to improve competitiveness. Therefore, continual inspection and corrosion control health assessments and investigations are key towards sustaining reliability and availability together with value creation through avoiding unplanned production loss and asset failures. The present paper discusses an inspection and corrosion control technical assessment performed on thirteen (13) subsea flowlines. These flowlines supply wet sour gas feed from two offshore fields, gather through two 36 in” trunk lines. In order to meet the health and integrity objective, the assessment covers a review on the susceptibility and control of three (3) damage mechanisms using available literature covering field and empirical data. In addition, a review and discussion on the available and required inspection methods to combat the susceptible damage mechanisms are performed. This review is extended to an exploration and evaluation of (6) inline inspection techniques and two (2) remotely operated vehicles (ROV) to complement damage mechanism inspection methods.

Integrity Assessment Case Studies of Time-Dependent Threats

Product Number: 51319-12928-SG

Author: Chukwuma Onuoha

Publication Date: 2019

$20.00

This paper summarizes pipeline integrity risk assessments that were conducted on different oil and gas pipelines. Internal external and stress corrosion cracking threats were comprehensively assessed considering historical records and several susceptible factors that were specific to each threat. The result of the risk assessment is a ranking of each pipeline based on known and established parameters which affect the likelihood or probability of a corrosion related event occurring and the “consequences” of a corrosion related failure. This paper will substantiate presented arguments using comprehensive case studies discussing risk assessments of various threats practical experience and lessons learnt.Key Words: Pipeline Integrity Risk Assessment Internal Corrosion External Corrosion Stress Corrosion Cracking Inline Inspection ACVG DCVG ACCA Cathodic Protection Indirect Inspection Severity Classification Data Interpretation.

Integrity Maintaining and Cost Saving Advanced CUI Detection Technique (PEC)

Product Number: MPWT19-14242

Author: Amro Hassanein, Ahmed Elsharkawi

Publication Date: 2019

$0.00

Corrosion under insulation (CUI) is a major problem for petroleum and petrochemical process industries that affects the plant mechanical integrity and attacks assets. CUI can result in sudden and hazardous leaks (safety concern), and plant shutdowns with high losses of production (economical concern).
Traditional detecting methods of CUI to cut a window in thermal insulation used to inspect visually, to measure the thickness, and then return thermal insulation back, giving high chance for water and moisture ingress, accelerating CUI, moreover big amount of scaffolding erection along with thermal insulation removal required.
SHARQ (Eastern Petrochemical Company, one of SABIC companies) is pioneer to study CUI, evaluating many Non–Destructive techniques has proven Pulsed Eddy Current (PEC) as the most effective technique in terms of integrity and cost optimization.
Considering all available techniques, all aspects studied, such as range of applications, features, and limitations, it is concluded and verified to meet our inspection plan strategy needs.
PEC does not require thermal insulation removal; optimize scaffolding erection, has a wide range of applications related to thickness, and temperature. PEC approved by international codes and standards (API) to meet RBI Meridium software requirements.
The validation study results show cost savings of more than 50% compared to traditional thickness measurement methodology, moreover it reduces EHSS (Environment, Health, Safety, and Security) negative impact reduces the probability of safety incidents due to reducing labor, man-hours, and eliminating many associated activities with potential hazard and risk.
PEC has high productivity, easily operated, and provides comprehensive and professional inspection report

Integrity Operating Window Development for Refinery Units and Implementation Through a Digital Platform

Product Number: MPWT19-15288

Publication Date: 2019

Integrity operating windows can be developed to account for any changes occurring during plant
operation that affect expected damage rate or susceptibility to damage.
A five-step methodology based on API RP 584 advice was developed for consistent identification of
integrity operating windows and subsequently applied to several plant units in different refineries.
A digital dashboard was also developed for collecting and trending all the parameters affecting each
IOW and possibly for performing advanced data analysis (which may lead to the development of
predictive models). This represents a further step towards reliable implementation of integrity
operating windows and their positioning within an asset integrity management framework.
