Topic: Challenges and Solutions for CP & Coating Surveys


Affiliation: Director, Allied Engineers- India


Abstract: Over decades for managing the external integrity of a buried pipeline, various aboveground continuous Cathodic Protection (CP) and Coating surveys have been performed globally. For many pipeline owners these are mandated by regulation every few years or remain a part of the owners Standard Operating Procedure (SOP). The surveys typically include Closed Interval Potential (CIP) On/ Off, Direct Current Voltage Gradient (DCVG), Alternating Current Voltage Gradient (ACVG), AC Current Attenuation (ACCA) and Depth of Cover (DoC).  
There are several challenges in performing these surveys which may lead to incorrect readings or missing indications, such as: 
- Subjectivity from the surveyor to find, mark and report the indications without transparency  
- Different surveys being performed at different times with multiple passes of the pipeline, leading to sources of error while integrating data and/or variance in results due to seasonal environmental changes and resistivity 
- Pipelines being buried under challenging surfaces such as concrete, road, gravel, dry soil etc. making it difficult to locate pipeline and/or measure potentials without a proper electrode contact  
- Certain indications not highlighted for the particular survey being performed, though exist  
- Unknown DC/ AC interferences, temporal or telluric effects  
- Difficult access for surveyors to walk the pipeline with a trailing copper wire always connected to pipeline, especially in urbanised areas  
These challenges can be overcome by utilizing advanced integrated survey techniques currently available in the industry, wherein surveys can be performed continuously and simultaneously in a single pass of the pipeline. In addition, the high-resolution automatic data capture with repeatable and auditable encrypted waveforms is made available for data analysts and asset managers to make supportable integrity decisions.

Dr. A. K. Tewari
Executive Director (Operations)


Topic: Operators perspective on Direct Assessment (DA) as an integrity assessment tool


Affiliation: Retired Executive Director (Operations), Indian Oil Corporation Limited


Abstract: Pipeline owners and operators have only a few approved, peer reviewed, standardized integrity assessment techniques for their assets. Although, pipelines are statistically the safest form of hydrocarbon transport, it is widely accepted and understood the associated risks in case of any untoward incident. The consequences of such an incident increases multi-fold when the human population along the right of way is relatively high for a densely populated country like India. Cross country piggable pipelines are at lower risk, as they are being regularly inspected using in-line inspection (ILI) and thereafter on a systematic repair/mitigation plan. Whereas, the city gas or upstream pipeline networks or the typical shorter lines which are designed as non-piggables, utilize the non-intrusive Direct Assessment (DA) as the accepted valid integrity assessment tool.  
 
With growing urbanization, pipelines being laid in common right of ways and aging assets which get interconnected with newer assets to form larger networks, the answer to their regular up-keep comes down to applying iterative methodologies such as Direct Assessment (DA) on these complex systems. This allows the Owner to keep operating their pipelines, simultaneously undergoing code compliant health assessment. This keynote presentation will discuss about the limitations of DA, and how best an Owner can overcome those to ensure the best results are obtained through the inspection campaign.

Head, Aqueous Corrosion & Protection Section


Topic: Fire Side Corrosion and Steam Oxidation of Advance Ultra Supercritical Power Plant Materials


Affiliation: Head, Aqueous Corrosion & Protection Section 
Metallurgy and Materials Group 
Indira Gandhi Centre for Atomic Research, Kalpakkam


Abstract: Advanced Ultra-Supercritical (AUSC) power plants with targeted steam temperatures and pressures as high as 720 ? and 31 MPa are being explored worldwide to enhance power efficiency and reduce CO2 emissions. The proposed 800 MWe Indian AUSC plant (Sipat Station, NTPC) will use Indian coal, and the performance of the indigenously developed boiler tubes is yet to be fully evaluated with Indian coal. Fireside corrosion (i.e. excessive metal loss in heat exchangers due to chemical reactions with the surrounding environment at high temperature) and steam-side oxidation are the major corrosion issues in coal-fired thermal power plants. Ni-base super alloys show significantly higher corrosion resistance than the Fe-base alloys in coal-ash environments. Also, Indian coal has high ash content that will lead to erosion on the fire side of the boiler tubes. Thereby, attaining adequate fireside corrosion and steamside corrosion resistance is still a challenge in materials for advanced steam-cycle applications. The talk will cover the important aspects of 1).Requirement of advanced materials for high temperatures 760 °C, and pressures 35 MPa steam in terms of erosion, corrosion, strength and oxidation resistance in AUSC environment. 2). Materials that limit the current technology: Focus on nickel-based alloys, 3) Need for the study of fire side and steam side corrosion of the major materials, and 4) Coatings requirement for steam oxidation and solid particle erosion protection. The programme on fireside corrosion evaluation of candidate structural materials under stimulated coal-ash and flue gas composition for Indian AUSC conditions are being pursued at IGCAR. Similarly, activities on Fire Side Corrosion Test Rig (FSCTR) to evaluate the fireside corrosion of Alloy 617M, and steam side oxidation of Alloy 304HCu under real plant life conditions (initiated under AUSC Consortium of BHEL, NTPC and IGCAR.) shall be briefly highlighted.

Topic: Coating System Performance Analysis & Assurance


Affiliation: Director Technical Sales Support,  
Jotun India Pvt Ltd


Abstract: Refinery & Petrochemical industry demands the most efficient coating system and thus service condition challenge conventional paint system used in our industry in many ways. 
Very high corrosive ambience and Operational flexibilities test the real-life performance of the coating system and in many cases, it is evident that performance is not adequate to meet the design criteria.  
Underperforming coating system cause severe impact on structural integrity and if not correctly rectified in time, it leads to huge operational complexities including metal replacement.  
To address such challenges, few additional prequalification criteria in addition to ISO 12944 guideline considerably improve the performance predictability, especially in critical or areas with higher corrosion exposure.  
In general Energy Oil & Gas Industry like Refinery , Petrochemical , Coal to chemical, Gas , Storage (Tank farm), Transportation (pipe line ), etc uniquely observe this critical performance issue, minor calibration in coating prequalification process may add considerable value addition.  
Commonly observed corrosion in these industries are General corrosion, Erosion, Pitting, Stress corrosion, CUI etc. Typically common corrosion protection mechanisms are Barrier, cathodic or inhibitive, out of it 1st two types are commonly used for higher corrosive exposure.  
In both the cases barrier layer of the coating system plays the most important role, barrier layer with higher pore resistance provide higher corrosion resistance with longer durability. Effectiveness of barrier layers can be verified by cathodic disbondment values, permeability or EIS () in addition to conventional tests like SST and Condensation.  
Such evaluation at prequalification stage clearly confirms the difference and dominance of selective systems. Coating system in combination with Galvanic & Barrier mechanism are commonly used with satisfaction for decades despite their specific formulation and applications challenges which defines the higher generic adoptability of such system in variable condition.  
On other side It is also observed that in some cases these generic combinations are unable to provide adequate protection despite using best quality products, typical example is Tank internal. Paint system in combination with inorganic zinc silicate & epoxies often observed with moderate to severe blisters after 2-3 years of exposure which is primarily due to inadequate barrier protection. Coating system higher barrier layer perform much better compared to paint system in zinc silicate combination.  
To summarize, minor calibration/addition in prequalification process demonstrate strong performance assurance, coating system in combination with zinc primer in immersed service are vulnerable to ageing exposure.

Topic: Importance of Corrosion in process safety management


Affiliation: Ex BPCL & Adjunct professor, ICT


Abstract: Damage from corrosion often leads to failures in refinery equipment, which interrupt refinery operations and create safety hazards. It has received wide attention in recent times due to some of the process safety consequence of loss of containment triggered by corrosion resulted in loss of lives / injuries apart from asset damage and major business interruptions. Hence, corrosion finds an increasingly dominant place (rightfully so) in process safety risk assessments.  
My focus in this talk is to emphasize the importance of understanding corrosion phenomena and develop action plans to combat corrosion thereby preventing process safety incidences. All refineries aim at their ability to identify risks and manage risks such that the impact is minimum even if the risk materializes. Several actions are taken towards achieving this, but we need to do much more.  
Emphasis must be in having all engineering disciplines developing appreciation for a strong link that exist between corrosion and process safety. We must accomplish this thru team building wherein the culture of risk identification and management is thru collaborative working of all the domain specialists in the team.  
The challenge is to reach a level in reading the process along with robust monitoring that we can predict the next potential failure and act before it becomes a reality. This is possible today with the expertise that are available in all the fields and tools available for data analytics.

Topic: Way Forward for Prevention and Control of Corrosion in Concrete Structures


Affiliation: Associate Professor, Dept. of Civil Engg., IIT Madras


Abstract: Many countries are witnessing a significant boom in the concrete construction sector. There is a huge demand for designing concrete structures with a target corrosion-free service life of 100+ years. Also, there is a huge demand for extending the service life of existing structures. These can be achieved by: (a) enhancing the resistance of cover concrete against the ingress of chlorides and carbon dioxide and (b) enhancing the resistance of embedded steel reinforcement against corrosion, in particular the initiation of corrosion, and (c) controlling the rate of corrosion propagation by cathodic protection. The performance of various steel-cementitious systems in these aspects will be discussed. Also, the nomograms developed for designing concrete structures for a specific service life will be presented.

Topic: Water – Elixir of Life: Managing it Sustainably


Affiliation: President, Ion Exchange (India) Ltd.


Abstract: Water is an essential building block of existence.  
Today more than ever, to meet the rising demand for water, it is imperative that water be effectively managed not just at the source but throughout its life cycle.  
The Central government through allocations for the water and sanitation sectors, aims to achieve the Sustainable Development Goal (SDG) 6 of ensuring availability and sustainable management of water and sanitation for all. These are welcome steps! 
Achieving water security and thereby achieving the water SDG, warrants a shift in paradigm encompassing holistic concerted efforts from all quarters. Changing the way we manage water today by applying the principles of circular economy have the potential to transform the current linear water systems to a circular system. Circular economy in the context of water can significantly reduce water stress as it aims to reduce, reuse and recover water. 
Companies such as Ion Exchange lead corporate efforts providing circularity in managing water, waste water, solid waste and waste to energy also to combat the growing water scarcity issue. Comprehensive circular technologies enable companies such as ours, cater not just to industries and municipalities but also to institutions, homes and communities - both urban & rural. We believe that past, current and future initiatives in effluent recycle, zero liquid discharge, treating municipal sewage and product and resource recovery along with source substitution of water (alternate sources of water) such as sea water desalination, could prove to be the most suitable alternatives to meet the growing water demand for achieving sustainability goals related to water.

Topic: Progress in Research on Corrosion Inhibitors


Affiliation: Faculty of Engineering & Technology, Aligarh Muslim University


Abstract: Corrosion costs the global economy billions of dollars annually. Protecting metals from corrosion is indeed a challenging task faced by academia and industries. As a result, experts are constantly working to find a sustainable corrosion-prevention strategy. The aim of the various corrosion control strategies is to find out the most efficient and cost-effective processes and to reduce the corrosion rate to a level that is acceptable. Each corrosion control strategy has its own complexities. The application of corrosion inhibitors is one of the most common strategy to counteract internal corrosion in various industries, including oil production, chemical processing, and aerospace etc. For over a century, corrosion inhibitors have been added to aggressive environments to protect metallic materials from corrosion. Even though corrosion inhibitors have been a standard research issue for decades, more advanced understanding is still required to win the challenge. In this connection, there is significant ongoing research in this area seeking to optimize the functionality of corrosion inhibitors, ranging from developing new active species which are environment friendly to gain mechanistic insights. A growing interest in the area of research on corrosion inhibitors can be depicted by observing the increasing number of published articles on corrosion inhibitors in the literature. So far, several organic and inorganic compounds have been evaluated as green and eco-friendly inhibitors, and a lot of work have been devoted to developing efficient green corrosion inhibitors extracted from plants, surfactants, biopolymers, ionic liquids, etc. The present talk aims to discuss the different auspects of corrosion inhibitors and to explore the progress and advancements in research on corrosion inhibitors.

Abstract: Removal of 100 to 1,000 gigatonnes of CO2 this century may be needed to achieve deep decarbonization and avoid exceeding the 1.5°C climate target. Nano wonder materials and nanotechnology is playing key role. Graphene has found its use in numerous industrial applications due to its unique properties. While its impermeable and conductive nature can replace currently used anticorrosive toxic pigments in coating systems, graphene can be an important component as a next-generation additive for many industrial applications (1). Graphene, a sheet of carbon atoms bound together in a honeycomb lattice pattern, is hugely recognized as a “wonder material” due to the myriad of astonishing attributes it holds. It is a potent conductor of electrical and thermal energy, extremely lightweight chemically inert, and flexible with a large surface area. It is also considered eco-friendly and sustainable, with unlimited possibilities for numerous applications. 
The current bottlenecks in using graphene & graphene oxide are the availability of cost-effective, high-quality materials from graphite and their effective incorporation into the product matrices.Removal of 100 to 1,000 gigatonnes of CO2 this century may be needed to achieve deep decarbonization and avoid exceeding the 1.5°C climate target.

Topic: Corrosion Protection of ship hull structures and seawater piping components


Affiliation: Senior Scientist, Naval Materials Research Laboratory (NMRL), Defence Research Development Organisation (DRDO), Ambernath


Abstract: Metals are most widely used for the fabrication of naval ship hull structures and for various marine engineering components used in seawater piping applications which include pumps, shafts, valves, etc., and therefore their protection against corrosion in aggressive seawater environments is of prime concern to marine designers, engineers and constructors. Selection of materials and protection methods to be employed depends on life cycle cost, criticality of the component and expected service life of the component. Corrosion protection of ship hull structures and seawater piping components has been the two most expensive maintenance burden costing huge financial burden to both ships' forces and repair activities. 
Hull structures and its appendages of naval ships are constructed by joining numerous assemblies/sub-assemblies / sub-systems made of HSLA steel, primarily by various welding processes. This being the most critical structure, its corrosion protection against the aggressive chloride ions of seawater and its structural integrity due to varying type of loads experienced by it due to operating machinery inside the ship and impacting sea waves from outside are of major concern and deserves utmost importance in maintenance schedule of the ship’s hull during its intended service life. 
In this paper, the corrosion protection methods employed for the ship’s hull structure through sacrificial anodes and Impressed Current Cathodic Protection (ICCP) systems along with recent developments in this field will be presented. Further the conjoint effect of seawater and the operational load on the ship’s hull structure leads to stress corrosion cracking and corrosion fatigue crack growth at highly stressed fatigue prone areas. Stress Corrosion cracking and fatigue crack growth studies conducted for development of indigenously developed ship building steel will be detailed along with mechanism of corrosion fatigue process, the various parameters affecting the crack growth rates and the effect of environment and the loading frequency on crack growth rates.

Topic: Role of nanoparticles on the corrosion-resistant properties of the electrodeposited and sol-gel composite coatings


Affiliation: Senior Principal Scientist Surface Engineering Division CSIR-National Aerospace Laboratories


Abstract: There is an increasing demand from the industries for the development of superior surface coatings with higher wear and corrosion resistance for improved performance of engineering components. Nanocoatings containing nanoparticles or consisting of layers that are less than 100 nm are being utilized efficiently to reduce the effect of a corrosive environment. Among the various surface engineering techniques, the electrodeposition method and sol-gel methods are highly promising due to their simplicity, cost-effectiveness, good compositional control, etc. Electrodeposited nickel (~40 m) is utilized in a large number of applications due to its strength, toughness and resistance to corrosion and wear. Nickel based composite coatings containing ceramics have been explored to combine the corrosion resistance and strength of nickel with the hardness, oxidation and wear resistance of ceramic particles and with the sole aim of achieving properties similar to hard chrome. Similarly, sol-gel based organic-inorganic hybrid coatings containing nanoparticles are explored as corrosion-resistant coatings for aircraft grade alloys. In the first part of the talk, the effect of addition of different types of nanosized ceramic oxides on the wear and corrosion-resistant properties of electrodeposited Ni-composite coatings will be dealt with. In the second part of the talk, the effect of different shapes of cerium oxide nanoparticles on the corrosion-resistance of Al-Si based inorganic organic hybrid sol-gel coatings (<10 m) will be discussed in detail.
