Hydrocarbon Fire Protection and Fire Engineering -YEP June Meeting

Hydrocarbon Fire Protection and Fire Engineering

By, Philip Hollyman MSc AIFireE MSFPE

Young Engineer Program June meeting was opened by George Winning  with a brief discussion on the Case Study which was delivered to the delegates last month with an update on the programme and the mentors.

Hydrocarbon Fire Protection is a complex; important topics that a young Engineer needs to focus on;

  • Passive Fire Protection
    • What is fire protection and why is it needed
    • Fire types
    • How PFP coatings are tested
    • Factors affecting the loading
  • Structural Fire Design
    • What is it and how does it provide cost and weight savings
    • Magic numbers and real project examples
  • Further Information
    • What information is available
    • Who are the governing bodies
    • Where do I find information

There was some good interaction from the floor with discussion on how Engineers could approach Fire Protection to meet the current project requirements to save weight and costs.

The evening closed with a networking dinner hosted by the Institute of Corrosion and AkzoNobel.

Our thanks as always goes to those who give up their free time to come and assist with the YEP programme and in particular Philip Hollyman from AkzoNobel.

Coatings & Linings and Introduction of Case Study By David Mobbs and Richard Carroll

Coatings and Linings

The May meeting of the Young Engineers program was held at the CB&I offices in London. This month the topic was Coatings and Linings which was presented by David Mobbs and was warmly received by the enthusiastic audience.  The presentation covered the high priority areas of coating including the requirement to qualify products to standards, the standards and what they mean, the testing methods required to achieve this qualification, some typical specifications and the pitfalls and Engineer can fall into. The new ISO 12944-9 formed the backbone of the discussion as it now covers all aspects of coating specification and system selection.

The discussion also looked at modern day options that could be adopted and how innovative ideas are also qualified in the new ISO standard and the requirements for their use.

The Case Study

Prior to the presentation the case study for the program was presented to the delegates. The case study was presented by Richard Carroll of Shell and he highlighted the importance of working together in the teams to deliver the required information as detailed in the document.

Each team will be giving a presentation to be delivered at the November ICorr London branch meeting, the winning team receiving a sponsored trip to NACE Nashville in 2019.

This year the case study is titled “Offshore Heat Exchanger Corrosion Failure” the delegates will be required to;

  • Review the design and operating data and propose a root cause
  • Define the failure scenarios
  • Describe a testing scope to confirm the root cause
  • Perform a corrosion risk assessment
  • Identify mitigation options to prolong the service life of the heat exchanger
  • Design materials for a replacement heat exchanger

We are extremely grateful to all those members of the Institute that give up their free time to help the cause not least the mentors this year, who are;

John Boran

Rob Doggett

Chris Googan

The teams will meet their mentors in the coming weeks and get going on the case study, a linked in page and drop box have been set up for the teams to help them with this process.

The delegates enjoyed an excellent meal on a canal boat in Paddington after the presentation, hosted by ICorr. A thoroughly recommended experience that all enjoyed.

The next YEP meeting will be on 20th June at CB&I in Paddington and the topic will be Hydrocarbon Fire Protection

Again, we would like to thank our Hosts CB&I especially Sadegh Parvizi for organising the venue, our sponsors BP and our speakers, organising committee and delegates who are travelling from Leeds and Newcastle to attend the event each month.

Subsea Inspection – The Future by George Gair of Subsea 7 and Integrity Management of Brownfield Projects: Challenges and Rewards by Monzar Najami – Principal Inspection Engineer of Oceaneering International

George Gair of Subsea 7, commenced the evening session with a thought provoking theme ‘Subsea Inspection – The Future’ that considered many aspects of the current cost reduction environment, where there is a major focus now on how to reduce costs by incorporating new philosophies / technologies.

George Gair – Global Inspection Manager for Subsea 7 presenting to ICorr ABZ

Very clearly the drive is to produce new and robust methods of harvesting sensor data; subsea hardware suppliers are looking at increased in-suite equipment monitoring and intervention methods; the oceanographic community has developed remote seabed environmental monitoring systems. George highlighted many significant indicators that show a definite trend towards smarter systems, a key driver being to learn and incorporate inspection technologies from other industries such as Aerospace, Automotive, Medical and Power Generation, together with more efficient use of gathered data.

Significant Integrity Failure found by Advanced Subsea 7 ROV.

Monzar Najami and Hooman Takhtechian of Oceaneering International followed on with a similarly stimulating discussion on the theme of, ‘Integrity Management of Brownfield Projects: Challenges and Rewards’ highlighting the many important analysis and data gathering areas of modern RBI – Risk Based Inspection methodologies

Monzar Najami – Principal Inspection Engineer of Oceaneering International

The presenters informed the large audience, that the greatest challenge to developing and implementing an asset integrity program during Brownfield development projects is the fact that project schedule and milestones often take primacy over integrity management processes, and in particular emerging vital integrity related interventions which can lead to conflict and disagreement.  Any delays in the implementation of these activities impede the Integrity Management Programme (IMP) and increase the level of risk to the facilities in the operating stage.

Key stages in an IMP project were highlighted as:

  1. Identify stakeholders early in the project (project team, operations, planners, site personnel)
  2. Define strategies and processes and add activities to the construction plan (integrated project activity approach)
  3. Analyze historical data (collect the available list of failures, anomalies and review root cause analysis)
  4. Material fitness for new process (review threats assessment and existing material suitability)
  5. Baseline inspections: Get in early (define scope and input your inspection requirements in the manufacturer’s ITP)
  6. Brownfield revamp activities: Scrutinize output (repair recommendations were challenged and resulted in major cost saving, and change in material selection)
  7. Tagging and RBA output alignment with the existing CMMS (understand the existing Computerized Maintenance Management System prior to your RBA to avoid major re-work)
  8. Deployment of new and advanced inspection technologies (to achieve major cost savings)
