Pipeclad 2060 MRO – Advanced Moisture and Damage Resistance for Pipeline Presentation

 

London Branch

The branch held its first technical meeting of the new season on 8th October, which was joint with LMS and its first meeting to be held virtually. Pablo Merino, the Cathodic Protection Technical Authority at CLH presented “A New CP Approach on Non-Isolated and Aged Pipelines: A Case Study”.

He described the case of an aged pipeline with an oversaturated CP System not achieving the full protection criteria. An in-line corrosion inspection revealed several corrosion features and a severely degraded coating system (in some locations almost completely gone). The pipeline in question was a 34 km, 60 + year old, 10” bitumen enamel coated pipe running parallel, in the same right of way, with six other pipelines all bonded together, one of which was bare. Various options were considered to remedy the under protected areas, namely (a) electrical isolation, (b) upgrade of the existing CP system, (c) coating rehabilitation, and (d) change CP criteria for a less restrictive one. Pablo discussed several options, (a) and (b) were not feasible, and for (c), the CP system had already been upgraded with twenty impressed current groundbed installations having a total output of 560 amperes, thus further upgrading was not feasible. Option (d) to re-classify the pipelines scheme as a “Complex Structure” under standard BS EN 14505, was considered as possible.

The new strategy is to confirm which BS EN 14505 “alternative methods of verification” suits the pipeline integrity, re-balance the existing CP system based on the External Corrosion Monitoring System (ECMS) and the adopted BS EN 14505 alternative method of verification (CP current optimisation).

Hence, the work currently in progress is to re-classify the pipeline scheme as “Complex Structure” as per BS EN 14505, and implement an ECMS using buried electrical resistance probes at strategic locations to verify that the reduction of the corrosion rate suits the pipeline integrity.

Numerous questions were answered by Pablo. A vote of thanks was given by Ben Moorhouse and he was presented virtually with a London Branch pen (and sent it by post).

The virtual TEAMS meeting was considered a great success with 40 attendees from around the UK. The benefit of the virtual presentation is that it can be followed by anyone and does not require a visit to central London. However, the networking with peers is sadly missing. This presentation can be found at https://www.icorr.org/london-branch-a-new-cp-approach-on-non-isolated-and-aged-pipelines/
The November meeting was devoted to the YEP Case Study presentations, as with other ICorr events this year, this was held online via TEAMS. This year there were 7 teams, who reported on their solutions to a case study about an onshore titanium pipe corrosion failure.

Several leaks had been found in titanium piping in a glycol desalination plant which required action to be taken. In particular, the teams were asked several questions on this, including, what further information was needed and discuss in detail any results or data provided, propose credible root causes for the defects and to described possible failure scenarios. They were also asked to consider how they would carry out a corrosion risk assessment, what mitigation option(s) should be implemented, and to propose alternative materials of construction for replacement parts.

After all the teams had presented their solutions to the problem, the judges retired to decide on the winners, who would receive an all-paid trip to NACE Expo, Salt Lake City, in 2021, curtsey of BP, the sponsors of the YEP programme. Team 4, mentored by Tasos Kostrivas (Mott MacDonald) comprising, Ryan Cobbs (Mott MacDonald), Izabela Gajewska (Intertek), Harry Wright (Element), Praveena Nkumaran (Worley Parsons), and Vincent Lemoine (Saipem), were declared the winners.

In addition, PIH Ltd are sponsoring one place on a NACE Leadership course to be held in Houston in September 2021. Each of the YEP students have been asked to fill-in a questionnaire which will be assessed by all the team mentors, to decide on the recipient.

All the presentations are now on the Institute website 
(https://www.icorr.org/yep-programme-case-study-presentations/), and it is intended to have a more detailed report in the next issue of Corrosion Management.

Steve Paterson commented after the event, “I thoroughly enjoyed the case study evening. I thought the quality of the analysis and presentation of the case study by each team was excellent. As I re-examined this failure over the course of preparing the case study, I realised that the original failure investigation could have been more detailed and would have benefited enormously from the work done by any one of the YEP teams involved in the case study task. It is ironic that there continues to be corrosion issues in the new desalination unit. Please pass on my compliments to all the YEP teams for a job well done and my congratulations to the winning team. There is some real talent in the pipeline!”

Not-to-Be-Missed Corrosion Conferences Online

Not-to-Be-Missed Corrosion Conferences Online

London and Aberdeen Branches Present More Events Online

The world may be in a state of continual flux and debilitating coronavirus restrictions, but there are some things you can rely on. One of those is the Institute of Corrosion, which continues to bring conferences, events, and meetings to your digital device.

Following the success of our online events earlier in the year – such as the Week of Webinars – we have news of two further online events. These are corrosion conferences that you will not want to miss. Read on to learn more, including how you can participate from anywhere in the world.

London Branch ICorr Meeting Goes Virtual

The London Branch of ICorr has announced its first ever virtual branch meeting. This is an evening event, starting at 6pm UK time (7pm CEST) on Thursday 8th October 2020, and will be a joint meeting with the London Materials Society (LMS).

This technical session will deliver a case study under the title ‘A New CP Approach on Non-Isolated and Aged Pipelines’. The presenter is Pablo Merino, Cathodic Protection Technical Authority @ CLH PS.

Here’s the premise:

  • An aged pipeline
  • An oversaturated CP System NOT achieving full extent protection criteria
  • An in-line corrosion inspection showing several corrosion features and a deficient coating condition
  • In some locations the coating is non-existent

Questions that must be answered include:

  • What can we do?
  • How we can progress from this situation?

This is a real case. It’s a big dilemma, and there are several options available. All need to be assessed before the most feasible solution from both a technical and economical perspective can be selected.

By the end of this meeting, we will have discussed all the possibilities and shared the solution. It’s an amazing ‘learn from the expert’ event.

To attend, click the link below to register. You will then receive login details and the ‘rules’ for this online meeting. (Oh, and don’t forget, there is one thing we can’t supply – drinks and snacks for the event. Yes, the London Branch is famed for its refreshments, but this time they are down to you.)

Event #1: ICorr

A history of well integrity in the operations phase and its business impacts to the oil and gas industry

Presented by Simon J. Sparke, International Well Integrity Ltd.

5th October 2020, 12:00 PM

Abstract – Well integrity really impacted our lives and became part of our culture following the Piper Alpha disaster in 1988, and the publication of the Cullen report and the impact of the Design and Construction Regulations (DCR) 1996. 

Since then in United Kingdom Continental Shelf (UKCS), Norway, and many other parts of the world, the industry is required to adhere to a wide catalogue of guidelines and standards such as the Oil and Gas UK guidelines (O&GUK), ISO-16530 well integrity standard, NORSOK D-010 and more, so that these have become part of the daily reading and way of life, to demonstrate how we as an industry should and do conduct our business of managing well stock throughout the well lifecycle.

This presentation will open with the history of well integrity, how it has developed, the implementation of key management software, the well examination process, and much more. We’ll also discuss how the industry has shaped our attitude on day-to-day business.

The on/offshore oil and gas production industry as well as the underground gas storage business with use of disused oil wells, and salt cavities, is highly regulated and governed. What is now becoming a common industry thread is the use of Well Integrity Management Software (WIMS), which typically follows the ISO-16530 standard, using the nine structured elements to look at the technical, operational and organisational element of the oil and gas sector in a structured way to allow reporting and independent review to the standard expected by a wide range of regulators.

This is further supported with institutions such as the International Well Control Forum (IWCF) and its certification programme for a wide range of staff working on wells, to ensure that they understand and recognize the risks associated with working on and around the well stock.

Finally, the recent work of O&GUK will be discussed, which has published competency guidelines to ensure that all operators maintain a transparent and auditable programme to ensure that workers are periodically reviewed for compliance to a minimum standard.

Event #2: ICorr

A review of glass flake technologies and short-term aerosol solutions for marine corrosion protection

Presented by Graham Greenwood-Sole, Managing Director of Corrocoat, Leeds

6th October 2020, 12:00 PM

Abstract – Corrocoat has been providing cost-effective anti-corrosion methods, materials and engineering rehabilitation expertise for over 30 years. They enjoy a proven track record in solving corrosion-related problems throughout industry, operating across five continents from more than 30 locations worldwide. Corrocoat’s business is extremely diverse, dealing heavily with the oil, power, mining, marine, petrochemical and many more industries that encounter corrosion issues.

This presentation will outline the benefits and function of glass flake within high performance linings, options for the technology using differing resin systems, for the protection of equipment operating in harsh process environments. It will discuss the advantages of this long-life technology and the critical importance of the right application techniques in pipework especially. Further, as the industry looks to shorter-term solutions to corrosion prevention, the use of surface-tolerant epoxies (which has recently become more prevalent) and the development of single-container two-pack epoxy aerosol technology will be discussed, as this may well prove an ideal solution for holding back corrosion ahead of major intervention programmes by plant operators.

Event #3: ICorr

What is proactive maintenance, and how does it differ from preventive and predictive maintenance?

Presented by Gary Whyman, Business Dev. Manager at Plantweb Solutions – Emerson Automation

1 hr Free 7th  October 2020, 12:00 PM

Abstract – As the world embraces a new age of digital transformation, staying on top of asset health is easier than ever before. Advanced communication tools keep personnel in touch to collaborate on developing production issues. Data from predictive intelligence applications and analytical tools are aggregated to create a holistic picture of equipment condition.

The challenge is getting the right information to the right person at the right time and making sure you can ‘close the loop’. 

This presentation will explain how you can leverage your existing ‘condition monitoring’ and process instrumentation infrastructure, alongside new digitalisation solutions. Integrating them with your existing Computerised Maintenance Management Systems will allow you to effectively close the maintenance loop and move to a proactive maintenance strategy.

Highly scalable digitalisation solutions mean that you can focus on areas that matter the most in the short term, evaluate the benefits and return on investment, and then expand to other focus areas. Implementing a new maintenance strategy may come with its own challenges; not only technical ones, but potentially procedural and cultural ones too.

This presentation will also touch on some of those challenges and weigh them against the expected benefits, to allow all the stakeholders – from those who will be using the new solutions through to management – to make an informed decision remotely.

Event #4: MCF

Integrity management of hydrogen transportation pipelines

Presented by Neil Gallon, Principal Engineer at ROSEN UK

1 hr Free 8th October 2020, 12:00 PM

Abstract – This presentation will illustrate a comprehensive integrity management approach supporting pipeline operators with the conversion of their existing natural gas grids and operations for transporting hydrogen. It will summarise the potential threats, and the changes or additions to current integrity management (and potentially operating) practices needed to monitor these new threats.

Event #5: MCF

Subsea surveys utilisation of high-sensitive field gradient sensor for optimisation of life extension

Presented by Svenn Magne Wige, Business Dev. Manager at FORCE

1 hr Free 9th October 2020, 12:00 PM

Abstract – A High-Sensitivity CP Field Gradient (FG) sensor was developed and has now been in use for several years. With the data recorded by the sensor, one can determine significantly higher accuracy on the CP status such as anode current output, overall potential distribution, and not at least repeatedly observed current drain to adjacent structures.

On mature structures it has been known for years that the true mean current demand is significantly below those recommended in the standards. Utilising the FG data from this high-sensitivity FG sensor, allows documentation of these low current densities, from which a very cost-efficient design basis for CP life extension can be formed.

London Branch

The branch has been planning for its next session of technical meetings which start in October, with a joint meeting with LMS on “A new CP approach on non-isolated and aged pipelines”, by Pablo Merino, the Cathodic Protection Technical Authority at CLH.

If face-to-face meetings are still not possible due to the corona virus pandemic, then contingency plans are in hand to hold these online. Once the details have been finalised, notification will be sent to the branch mailing list, and will also be posted on the Institute website. The AGM for the 2019/2020 season still needs to held, and it is intended that this will take place at the first evening physical meeting.

London Branch

As with other Institute of Corrosion meetings, the branch’s March and April technical presentations had to be cancelled due to the pandemic. The committee held an online meeting under its new chairman, Ben Moorhouse of BP, to discuss how to move forward under the current situation. The committee would like to thank Paul Brooks the outgoing chair for the hard work he put into the branch during his tenure. Contingency plans were discussed to hold a replacement Annual General Meeting and next season’s regular talks (October onwards) via online video conferencing, if they cannot be held in person. Further information will be available in later issues of this magazine, and on the Institute website.
