Optimisation of maintenance and inspection programmes through risk analysis can be used for coating maintenance. The risk picture can be described by 1) Scenario, 2) Frequencies, and 3) Consequences, for protective coatings. A systematic approach for optimisation of the maintenance programme has been developed.
Outdoor tests and accelerated weathering experiments have been carried out to confirm the weathering performance of coating systems with ambient cure fluoro-polymer topcoats. The results showed that the protective performance of such coating systems was superior to other topcoats such as polyurethane coating.
Fitness for purpose of low temperature cure liquid-applied coating systems for pipeline maintenance and repair. Potential revisions to incorporate low temperature cure liquid-applied coating products into Table 1 of CSA Z245.30-14 will be presented along with commentary related to the deviations from the standard.
Corrosion management (CM) is a rather new concept and expertise. Its origins go back to early 2000's. The CM concept emerged from the UK's offshore oil and gas industry; from where the author also started his professional career.
Due to this newness and a vast multitude of application benefits, there has been a constant growth in demands for the provision of CM awareness, training, expertise and consultancy year after year.
The author has so far compiled a total of four CM books and this one is the last in the series. It is also the most comprehensive among the four books, with a greater emphasis and focus on CM field implementation.
Therefore, if one intends to implement CM across their asset(s), then this book could provide them with the required advice, instructions and guidelines on proper CM field implementation for both hydrocarbon and non-hydrocarbon industries.
The book covers subjects from how to define the scope of work to report writing and communicating the latest integrity findings.
It is written in a simple and jargon-free language and intended for various disciplines including: corrosion and integrity engineers, inspection engineers, pipeline engineers, process engineers, maintenance engineers and asset integrity managers.
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.
Impressed current cathodic protection (ICCP) is one corrosion management approach adopted by the Port of Newcastle (PoN) for their reinforced concrete wharves. The Port’s West Basin 3 wharf, has ICCP systems installed to select substructure concrete elements (beams). The West Basin 3 ICCP system to the front beam soffit section was installed in 1998 (rear beam soffit sections having been protected from 2014). Other ICCP systems have also been installed by the PoN during the period 2002 to 2005 for the West Basin Wharf 4, East Basin (1 & 2) wharves and the Kooragang K2 wharf. This paper provides background to the different ICCP systems utilized and details performance results for the West Basin 3 front beam ICCP system dating back more than 20 years. Monitoring results are presented and discussed. Performance assessment to protection criteria is undertaken and the CP system maintenance requirements are summarized.
