Topic: Digital Solutions for Corrosion Control

Affiliation: Group CEO & CTO

Abstract: If there is one realisation in our current lifetime, it is the fact that a pandemic can force a global lockdown and severely disrupt our day-to-day lives. Though challenging, there are critical activities that need to be carried out nevertheless. Top on the list of critical activities are the monitoring and controlling the health and integrity, especially in areas concerning corrosion, of assets such as pipelines, platform, refineries and jetties, which left unchecked, could lead to dire consequences. 
Traditionally, operators used to rely on skilled personnel to periodically be on the ground at the facility, recording tedious data points to maintain and ensure safe operations manually. Such monitoring activities require high labour cost and time, leaving operators to heavily rely on manual data collection, in which some can be difficult due to access and subject to human errors.  
However, in recent years, with the development of smart sensors and high volume of data transmission and storage, remote monitoring technologies have been developed to offer real-time data, remote access and diagnostics, which reduce and eliminate the need for long manhours involved in inspection and maintenance, and operational down-time. Over the last 2 years there has been accelerated developments in these technologies to allow a more easy-to-deploy and user-friendly approach given that most operators had to work from home or countries away from the assets. The side benefit from this development has also, in turn, provide a huge savings in time and cost to the operators by not only maintaining and operating more efficiently, but also eliminating the risk of having failures and costly unscheduled repairs at their facilities.  
This paper will discuss in detail the need for the Corrosion Industry to embrace digitalisation and the reasons why these technologies are here to stay. The technologies to be discussed cover the remote monitoring of corrosion and erosion rate of pipeline and piping, and the performance of cathodic protection system for both ICCP and galvanic corrosion protection systems.

Abstract: An unexpected failure of 316L Stainless Steel instrument tubing occurred in a high pressure Hydroprocessing unit resulting in a shutdown of the unit. The tubing system consisted of a compression type fitting commonly used in instrument systems and had only been in service for 3 years when the failure occurred. The failed tubing samples were removed for metallurgical analysis and determination of damage mechanism.  
Metallurgical analysis and finite element analysis of the tubing identified excessive cold working leading to hydrogen embrittlement as the primary mode of failure. This paper details the investigation into the failure to arrive at the root cause and the preventive measures adopted to assess the installed population of tubing in similar service.  
Key Words: Stainless Steel Instrument Tubing, compression type fitting, cold working, hydrogen embrittlement, finite element analysis

Topic: Mitigation of stress corrosion cracking in boiling water reactors: noble metal chemical addition

Affiliation: Paul Scherrer Institute (PSI) 
Laboratory for Nuclear Materials 

Abstract: Stress corrosion cracking (SCC) in reactor internals and recirculation pipes is one of the major degradation issues in boiling water reactors (BWRs). Efforts to provide mitigation of this cracking have led to the development of noble metal additions (Pt) to the reactor feed water. Under moderate hydrogen water chemistry conditions the Pt nanoparticles, formed in-situ and deposited on the reactor component surfaces, work as catalysts for the efficient reduction of the oxidizing species formed by radiolysis. The catalytic property of the surface is now able to lower the electrochemical corrosion potential without the negative side-effects of the classical hydrogen water chemistry. To verify and optimise this technology called Online NobleChem (OLNC), a research project was started at PSI, investigating the deposition and distribution behaviour of Pt in BWRs. From a scientific point of view and based on the results gained, some recommendations for OLNC may be formulated: The Pt injection should be performed at a slow rate under reducing conditions for extended periods of time. Applications should be repeated on a regular basis to compensate for Pt erosion and to protect new surfaces and they should start as soon as feasible after plant start-up. Pre-oxidation of new components may contribute achieving higher Pt loadings early on. Even though extremely small amounts of Pt can be sufficient to mitigate SCC, it is important to note that the Pt surface loading value alone is not sufficient to fully judge on the catalytic properties of OLNC-treated component surfaces. The Pt inter-particle distance seems to be a more suitable parameter.

Topic: Under-paint corrosion sensing technologies for defense and engineering sectors

Affiliation: Sr. Principal Scientist,  
Surface Engineering Division,  
CSIR-National Aerospace Laboratories

Abstract: Under-paint corrosion sensing in aircrafts is a challenge due to the thickness of  
the aerospace paint layers consisting of ~25µm of Primer layer and ~25µm of polyurethane layer resulting in ~ 50-60 µm paint layer. Aircraft size and the type of corrosion which generally occurs in AA2024-T3 are additional disadvantages. Corrosion being localised, placement of sensors, number of sensors and points where they can be hosted is challenging, in addition, to the paint thickness. Under-paint corrosion sensing has been approached by many methods with little success. Several approaches such as indicator method, electrochemical, fluorescence based fiber optic corrosion sensors for corrosion detection in incipient stages have been attempted and applicable to localised regions but difficult for monitoring the entire aircraft due to the inherent limitations listed above. Indicator method and fluorescent colour changes due to metal–ligand complexation although showed promise on the substrate but imaging the same could not be realised under- paint due to the paint layers. Spectroscopic techniques such as thermal imaging and Terahertz imaging offered the solution and under-paint corrosion imaging was possible. The advantages, disadvantages and challenges of the various approaches are discussed. 
Keywords: Corrosion sensing, AA2024, Underpaint, Hyperspsectral, Thermography, Fiber optic, fluorescence.

Topic: AC Mitigation Criterion and the impact on Cathodic Protection Operations

Affiliation: Keynote Speaker 

Abstract: AC Mitigation is a recognized threat to the integrity of pipelines in shared AC right of ways. This presentation will discuss what is AC Interference, how to properly mitigate AC Interference and the impact that AC Mitigation has on how the pipeline operator must control their cathodic protection system when AC Interference is an issue. This relationship between AC Mitigation and CP Operations is a critical issue that must be accounted for in the design and operation of both systems.

Topic: High Level DC Interference Assessment

Affiliation: Reignite (Pty) Ltd - CEO

Abstract: Direct Current (DC) interference has become a particularly complex subject particularly in areas where multiple pipelines pass through the same right of way. Numerous methods have been developed to assess the effectiveness of Cathodic Protection (CP) on pipelines under such conditions making for significant debate around the best suited approach to manage interference currents. 
This presentation raises specific topics surrounding typical DC interference conditions, sources such as DC traction railway networks, other CP systems, High Voltage DC powerlines and Telluric activity. A few case studies are presented to look at the probable mathematics and the actual field conditions with the real risks of failing to manage DC Interference adequately. Recent changes in monitoring standards are touched on to provide some context for the future direction pipeline owners may wish to take in securing the integrity of their pipeline assets over the long term.

Topic: High Resolution Indirect Aboveground Survey for Non-Cathodically Protected Pipeline Network – Case Study

Affiliation: Deputy General Manager, 
Oil India Limited

Abstract: Pipelines are essentially the safest means for transportation of oil & gas and their products since the 19th century. Early 20th century saw the first use of coatings applied to the external surface of the pipeline in order to prevent corrosion. The application of Cathodic Protection to prevent corrosion in pipelines was first applied in the 1930s and spread slowly across the world. 
Assam was the first state in Asia where an oilwell was discovered and commercial production of petroleum was started. Assam has some of the oldest pipelines in India, which have been enduring the ever-changing population, urbanization and harsh weather. Oil India Limited (OIL) owns an extensive network of pipelines which are transporting crude oil and gas in upper Assam districts of Tinsukia, Dibrugarh, Sivsagar, etc. 
OIL planned to undergo a code compliant integrity assessment for their non-Cathodically Protected pipelines. Direct Assessment (DA) was selected as the tool to ascertain the health of the pipelines and provide a Fitness for Service compliance. In the absence of a Cathodic Protection (CP) system, a customised methodology had to be proposed for the inspection. A high resolution state-of-the-art integrated indirect inspection technique was utilized to assess the threat of External Corrosion and Stress Corrosion along with a certified Internal Corrosion Predictive Modelling software for simulating and predicting internal corrosion and pipeline wall thickness losses. 
The advanced integrated indirect inspection technology helped identify and declutter the extensively jumbled spider-webbed network of non-CP pipelines. The adaptability of the Direct Assessment methodology to cater to a wide variety of pipeline issues by customisation is what makes DA a versatile tool to perform inspections especially for atypical situations. 
This presentation provides an insight into the methodologies of Internal, External and Stress Corrosion Cracking Direct Assessment to proactively gauge the health of pipelines.
