“A diversified approach to utilizing volatile corrosion Inhibitors (VCI)’’ – Talk by Philip Low, European/Middle East/GCC Business Development Manager, Zerust Oil & Gas.
The presentation will shed light on various approaches using volatile corrosion inhibitors (VCI’) technology in mitigating corrosion on pipelines, pipeline casing protection and above ground storage tanks.
Finally, a novel methodology for addressing CUI and Scab Repairs using a self-amalgamating inhibitor fused tape:
What are VCIs and How Do They Work.
An explainer and short animation on how the technology works in a 3 phased protective approach.
Above Ground Storage Tanks (AST’s)
We never know when, but ultimately all CP systems under storage tanks fail. When they do, there are not very many easy or inexpensive ways to repair or replace them. Whether you are building new tanks or involved in an API 653 inspection and the data indicates that the CP is not protecting everywhere, it is possible to install a backup plan.
This presentation will examine the installation of VCI delivery systems for various civil configurations and geometries.
With changes to regulations in the US, VCI can be used to mitigate corrosion under tank floors in conjunction with CP or in many cases, in lieu of CP. Information on the delivery system options will be presented, and data demonstrating the symbiotic relationship between VCI and CP will be shared. There are several delivery system designs based on the foundation design of the tank. These minor modifications to a tank foundation can significantly reduce cost and downtime in the future.
Summary: What do you do when your Cathodic Protection system does not last until the 653 Inspection? Can you build in a backup system inexpensively and easily? This discussion will examine options which can be utilized or installed during a current inspection or construction which may enable the enhancement of a weak or failed CP system, prior to the next inspection.
Pipeline Casing Protection and Using VCIs
NACE and PHMSA (DOT) have ratified the use Vapor Corrosion Inhibitors (VCI’s) as a corrosion mitigation strategy,
This presentation will focus on what the regulations from NACE, CEOCOR and PHMSA (DOT) have ratified the use Vapor Corrosion Inhibitors (VCI’s) as a corrosion mitigation strategy, and how they describe Multiphase delivery options including: “Dry Powder”, “Gel” and “Slurry” applications and when to choose each. Case studies will be shared from the most common Gel applications.
VCI’s to Prevent Generalized Internal and Microbial Internal Corrosion in Facility Pipes
A recurring issue during the construction and commissioning of facility pipe assets is the creation of internal corrosion threats due to leftover hydrotest water. Available methods for removing the water entirely, or applying inhibitor chemicals to the hydrotest medium, are time-consuming and expensive. A major Oil and Gas client applied vaporous corrosion inhibitor (VCI) chemicals in lieu of other methods which would mitigate the internal corrosion threats. This method proved to be very effective at mitigating both biological and generalized internal corrosion. A case study will be shared.
A Novel Methodology For Addressing Corrosion Under Insulation (CUI) and Scab Repairs Utilizing Corrosion Inhibitor Impregnated Self-Amalgamating Silicone Based Tape
Zerust Inhibitor Tape (ZIF) was specifically designed to combat the many areas to address when we evaluate a corrosion protection mechanism for CUI and Scab repairs, the main challenge is creating a physical barrier between the steel substrate and insulation medium.
ZIF provides this barrier in the form of a robust silicone based self-amalgamating tape, in addition to the robust outer nature of the tape; it is also impregnated with a corrosion inhibitor to combat any potential water or sweating of the line.
Finally, the tape is translucent to allow ease during inspection and due to ZIF having no glues/resins/primers for the adhesion mechanism; the tape is easily removed for allowing inspection cycles. The tape has also recently passed ISO-19277
Preservation of assets during idle or mothballed periods including spare parts and critical spare parts
Oil platforms including MDU’s, fixed, land and FPSOs are an integral part of modern day oil production. Not surprisingly, the number of rigs in operation at any given time is tied directly to the price of crude oil. The collapse of oil prices in 2020 due to the global pandemic has caused a large number of rigs to be mothballed albeit cold, warm or hot stacked as well as many high value critical spares to sit idle for prolonged periods of time, which of course they are never designed or engineered to do so.
An offshore oil platform is a very expensive asset, as is all associated parts and equipment; the average cost of an offshore rig is around $650+ million. As such, it is critical to put in place a robust preservation strategy to safeguard and prolong asset/equipment life. This statement is also true for spare parts and critical spare parts during storage and lay up, the topic will cover proactive approaches to preservation.
About the presenter:
Philip Low, European/Middle East/GCC Business Development Manager Zerust Oil & Gas.
Phil brings 25+ years’ experience in the Global Oil and Gas industry.
Having developed a wide range of skills within project and site managerial roles across the Uk and Norwegian O&G sectors, His understanding of the many challenges faced by maintenance and construction teams in this environment is invaluable when dealing with our customers and clients and the many problematic issues they face.
With responsibility for asset and corrosion management and fabric maintenance on various onshore and offshore facilities, Phil has continued to add to his knowledge and help develop new preventative techniques for a number of issues surrounding these facilities. This has included Refineries, Tank Farms and Offshore platforms.
With this proven track record in corrosion management and coating application, Phil has brought a new understanding of the challenges faced by these different types of sites and an ability to deliver cradle to grave project management for clients. Ever the innovator, he developed and headed a global tank and terminal maintenance team to help identify, assess and prevent a range of corrosion issues on Aboveground Storage Tanks (AST’s), Pipelines, Jetties and the associated valves and fittings. He continues to show a keen desire to bring new solutions to old problems and is often involved in new think tanks and innovation groups.
Phil is also an active member of Nace and CEOCOR.
