BakerRisk is pleased for the opportunity to participate at the Mary Kay O’Connor Process Safety Symposium (MKOPSS) 2020 Virtual Conference. BakerRisk will have a virtual booth with a lot of available information and learning resources for download. For the second year running, BakerRisk will be joined by FORTRESS Protective Buildings, LLC to discuss building risk mitigation solutions for your facility. In addition, our presenters below will present their listed topics.

Although we will miss meeting in-person with fellow attendees, we are delighted that the virtual platform will provide the opportunity to video chat! Our presenters will be hosting a virtual Q&A session over Zoom on October 20th. Karen Vilas of FORTRESS Protective Buildings will also join the team to answer questions from the attendees.

Tuesday, October 20th – 4:30pm

Track I: Risk/Consequence Analysis & Design Aspects.
Session: Layers of Protection: Relief Systems II
Todd Drennen, P.E., Senior Process Safety Engineer, Presenting:

“Failure Under Pressure: Proper Use of Pressure Relief Device Failure Rate Data based on Device Type and Service”

Component failure rate data is used in a variety of quantitative and semi-quantitative study methods related to process safety and reliability, including Fault Tree Analysis (FTA), Quantitative Risk Assessment (QRA), and Layers of Protection Analysis (LOPA).  This presentation examines pressure relief device failure rate data from multiple published sources, categorizes the data based on device type and service, and then seeks to develop guidelines for determining probability of device failure on demand based on the proposed device type and service categories. Additionally, the presentation provides commentary on the administrative aspects of relief device handling relative to observed relief valve reliability.

Wednesday, October 21st – 10:45am

Track I: Risk/Consequence Analysis & Design Aspects.  Sessions: Risk Mitigation
Rafael Callejas, Ph.D., P.E., Senior Process Safety Engineer, Presenting:

“Development of Risk Mitigation Programs using a Quantitative-Risk-Based Approach”

Once the hazard and risk profiles have been determined, owners/operators are struggling with implementing a prioritized action item list to systematically drive down the site risk profile to As Low As Reasonably Practicable (ALARP).

We use example case studies to demonstrate how a quantitative-risk-based approach can be leveraged in a risk mitigation program to optimize risk mitigation solutions such as building reinforcement, building replacement, and/or scenario mitigation. Also, we show examples of facility siting issues that the processing industries struggle with, such as focusing on implementing solutions to mitigating explosion hazards while neglecting other equal or high risk hazards, or implementing solutions company-wide that might be only effective for some assets, which results in unnecessary costs that do not mitigate the risk effectively.

Presentation slide - Fireball and flame venting comparisons

Wednesday, October 21st – 1:45pm

Track V: Explosions.  Sessions: Explosion Phenomena II
Peter Diakow, CFEI, Senior Blast Effects Consultant, Presenting:

“Fireball and Flame Venting Comparisons: Test Data, CFD Simulations and Industry Standard Predictions”

This presentation discusses flame jetting/venting and fireball propagation that occurs when an enclosed explosion (deflagration) vents to the outdoors.  Comparisons are made between test data (BakerRisk DLG Tests), standard industry predictive methods (NFPA 68 and EN 14994) and computational fluid dynamics (CFD) analyses conducted with the FLACS code.  The information is relevant for process buildings/enclosures and/or equipment that is (or should be) protected by deflagrating vents.

Wednesday, October 21st – 4:30pm

Track V: Explosions: Explosions Phenomena II.  Sessions: Consequence Analysis: Flammability
J. Kelly Thomas, Ph.D., CFEI, Vice President, Director of Blast Effects Engineering, Senior Principal Engineer

“The Use of Bent Poles as a Detonation Indicator”

This presentation discusses whether the deformation of slender columnar objects (e.g., poles) can serve as an indication of whether a vapor cloud explosion was a deflagration or a detonation.  The analysis covered in the presentation shows that the deformation of such objects is not necessarily a reliable indication of whether a detonation has occurred or not.
