Cathodic Protection (CP) System at Gas Wells Maintenance and Troubleshooting

Product Number: MPWT19-14286

Author: Mohammed M Alsaaq

Publication Date: 2019

$0.00

A cathodic protection (CP) system reduces corrosion by minimizing the difference in potential between the anode and the cathode. This reduction can be achieved by applying a current to the structure to be protected from an electrical source. When enough current is applied, the whole structure will be at one potential, thus anode and cathode sites will not exist. CP is commonly used on many types of structures, such as pipelines and underground storage tanks.
The paper is about an effort to improve Southern Area Gas Producing Facilities’ (SAGPF’s) CP system in compliance with all related Saudi Aramco standards, procedures, and GIs, and provides in depth analysis and recommendations to mitigate CP system challenges, and to make CP system reliable. In addition, the study aims to identify key tasks to minimize the effect of component failures and to increase the reliability of SAGPF remote monitoring units, to get accurate data. The onsite CP system survey was performed from April 26 to September 30, 2018, for all SAGPF. This paper is focused on the major challenges, such as equipment failures, operational deficiencies, and technical recommendations to make the CP system efficient and reliable.

Combining RMU, Annual Survey, and Groundbed System Design Data to Predict Capital Replacement Needs

Product Number: 51324-20805-SG

Author: Matt Barrett; Mill Jawed; Dylan Bolch; William Maize; Tony da Costa

Publication Date: 2024

$40.00

We present a procedure to estimate the remaining service life of an impressed current groundbed using data analytics techniques to combine the various manually and remotely collected measurements, and rectifier groundbed metadata. Multiple data sources, including commissioning data, annual survey data, remote monitoring data were combined to create a consolidated dataset spanning over ten years for each impressed current cathodic protection (ICCP) rectifier groundbed. Using advanced analytics algorithms applied to ICCP rectifier groundbed sites, weighting factors have been calculated to determine the influence of each dataset on the estimated groundbed remaining service life. This work builds on previous presentations at AMPP Corrosion 2021 and 2022, where seasonality and historic trends in rectifier resistance measurements were modelled. By including additional datasets describing the location at the time of installation and the historic survey measurements, a more robust prediction can be made.

Considerations Associated with the Selection of Electrochemical Protection Systems for Reinforced Concrete Structures

Product Number: 51323-19045-SG

Author: Atef Cheaitani, Samir Cheytani, Martin Cheytani

Publication Date: 2023

$20.00

Impressed current cathodic protection (ICCP) for reinforced concrete structures has been installed on numerous bridges and wharves in Australia over the past 40 years. The exposure conditions at the majority of these bridges and wharves made them more susceptible to chloride-induced corrosion.

The ICCP systems in Australia are designed, installed and monitored in accordance with the global cathodic protection standards such as AMPP Standard SP 0290-2019, International Standard ISO 12696:2022, and Australian Standard AS 2832.5 – 2008 (R2018).
