Dealing with Changing Regulations -
  Dr. Tom Bubenik

In the early 2000s, pipeline companies began implementing Integrity Management Programs in response to regulations ordered by Congress and promulgated by PHMSA.  Now, with a decade of experience, PHMSA is changing the rules.  Learn what’s happening and why. 

Dr. Bubenik will give a brief history of the IM regulations, highlighting the failures that led to the push for integrity management by Congress and PHMSA.    

Tom will trace operator compliance and discuss the effectiveness of Integrity Management Programs in terms of the numbers and types of incidents - both before and after the regulations.  He will then compare and contrast recent high profile failures with those that led to the original regulations. 

Finally, he will review recently proposed rules and how those changes will impact pipeline companies.

Dr. Bubenik has 35 years of experience involving pipeline integrity.  Before joining DNV GL, he held senior scientific and management positions with Battelle and Exxon Production Research.

Tom has in-depth experience in pipeline degradation, including seam-weld fatigue and SCC, integrity management, fracture mechanics, defect assessments, and regulatory compliance. 

He’s been actively involved with professional organizations such as API, ASME, NACE, PRCI and GRI and has authored over 50 technical publications.  

Optimizing Preventative and Mitigative Measure Selection -
  Tony Alfano, P.E.

The centerpiece to a successful risk management program involves identifying and mitigating high risk locations along a pipeline system through optimized preventative and mitigative measure selection. The ability of a company to achieve this outcome is often limited by the characteristics of the supporting risk assessment program. DNV GL has developed a set of guidelines which, when implemented, lay the foundation for a risk assessment program which can overcome these limitations allowing for risk intelligence to guide this process.  DNV GL first published The Essential Elements of Pipeline Risk Assessment in Pipeline & Gas Journal.  The Elements were developed, in part, in anticipation of more stringent ‘smarter risk assessment’ measures envisioned by regulators.

Mr. Alfano will cover all aspects of conducting systematic, measureable and robust pipeline risk assessments leading to PHMSA’s stated goal of improved integrity management and increased public safety.  Mr. Alfano will demonstrate how adopting a risk assessment program following the Essential Elements can be used directly for optimizing preventative and mitigative measure selection.

Mr. Alfano will:
•    Discuss the make-up and methodology of the Elements
•    Provide example tools and processes for leveraging risk intelligence
       into business decision making
•   Supply materials and methodology for a helpful self-audit developed to
       measure current (or planned) assessments against the Elements

Tony Alfano, P.E.

Mr. Alfano is DNV GL’s Head of Section for Risk Solutions with primary focus on risk management of pipeline and facility assets. 

He has significant experience working with pipeline operators to update their existing risk assessment programs into higher-value risk management programs. 

He has core experience with numerous pipeline integrity management assessments, techniques, and regulations which help him bridge the gap often found between a pipeline operator’s integrity and risk departments. 

Build on Your Foundation to Efficiently Develop Your Pipeline SMS -
  Megan Weichel

The recent introduction of API RP 1173 for Pipeline Safety Management Systems (SMS) has left many operating companies wondering where to begin.  When developing an SMS, it is essential to first know where the company is now and where the company intends to go with regard to risk management, pipeline safety management, pipeline and facility integrity management, and other forward-thinking programs and systems.

Ms. Weichel will discuss the key considerations and first steps for developing a management system that aligns to API RP 1173, including the following topics:

  • Utilizing gap assessments to determine how to best leverage what is already in place
  • Starting on the right foot with an effective Leadership and Management Commitment element
  • Utilizing effective incident investigation methods to prioritize development efforts
  • Closing gaps with internal best practices

She started with DNV GL in Houston in 1998, and after a brief stint in the glass industry, she moved to the company’s Dublin, Ohio, office. She was drawn into the oil and gas industry by way of process safety management work while writing mechanical integrity system documents and procedures.

Megan now focuses primarily on assisting pipeline companies develop and improve management systems for Facility Integrity, Risk Management, Process Safety Management, and HSE, performing audits, and developing and assessing management system components. In her time at DNV GL, she enjoyed a 3-year stint as an embedded Process Safety and Risk subject matter expert at an operating company, where she was able to experience first hand the challenges operators face when implementing and modifying management systems.

Simulation for Mitigative Design and CP Troubleshooting - Shane Finneran, P.E.

Pipelines sharing, paralleling, or crossing high voltage power lines (AC or DC) or electric rail traction systems are subject to electrical effects. If the interference effects are high enough, they may pose a safety hazard to personnel or the public, or may compromise the integrity of the pipeline. In such cases, an evaluation of the risk to personnel safety, coating damage, and corrosion is recommended. A mitigation system can be designed for those areas where potentials or current densities are above permissible limits.

Predicting electrical interference on pipelines is a complex problem, with multiple interacting variables affecting the influence and consequences. For this reason, computer models have been developed to accurately simulate a collocated pipeline’s susceptibility to AC or DC interference, identify locations of possible current discharge, and design appropriate mitigation systems to reduce the effects of interference.

Mr. Finneran will provide background information into the technical factors influencing high voltage interference, present a summary of the severity rankings associated with each factor, and address relevant guidelines and standards. The presentation will also address state of the art computational modeling techniques for simulating high voltage interference and designing mitigation and cathodic protection systems.

Hydraulic Simulation for Analyzing and Reducing Operating Costs  -
  Michael Bednorz

For the majority of pipeline operators, the emphasis has now swung from “increase capacity” to “reduce costs”. Fortunately, the high-fidelity hydraulic simulation models built and implemented for capacity and surge analysis can be “re-purposed” to help with cost analysis and optimization. Existing SynerGi Pipeline Simulator (SPS) models can be used for accurate calculation and optimization of the costs of power, drag-reducing additives, batching, and other pipeline operations. This presentation covers some of the benefits and “how-to’s” for modifying and using the existing pipeline models. A case history will be presented.

Topics include:

  • Review of the data and level of accuracy needed for power cost analysis
  • Structuring and implementing cost calculations
  • Typical decision-making and optimization algorithms
  • Methods for inputting data and setting up parametric cases
  • Methods for automating batch cycles, DRA injections, pump start/stops, and others
  • Tracking and interacting with the progress of the cost algorithms
  • Capturing, reporting, and exporting the results for further processing
