Case Study: Flare Management Plan

Posted by Dustin Smith, P.E. on Dec 6, 2018 4:38:59 PM

The Opportunity:

A major United States refinery, with a significantly high Nelson Complexity Index rating, had nine flare stacks and multiple engineering contractors working within the facility which made managing their flare design and documentation a challenge.

Case Study: Flare Modifications Due to Rate Increase

Posted by Dustin Smith, P.E. on Dec 6, 2018 4:28:04 PM

The Opportunity:

A major United States refinery was in the process of installing a site-wide rate increase and hired a competing engineering firm to perform the feasibility study. The engineering firm sized their crude fractionator and recommended new relief devices that would require modifications to their existing flare header. The refinery’s corporate office called Smith & Burgess and asked us to perform a third-party review on the engineering firm’s recommendations.

Case Study: Elimination of a Remote Flare System

Posted by Dustin Smith, P.E. on Mar 4, 2018 6:09:00 PM

The Opportunity:

An offshore floating production facility was originally designed with two flares: one on a boom riser and the other remotely located. Due to the design, the remotely located flare required large amounts of gas to operate. The site was interested in reducing operational costs and emissions by consolidating the two flares into the flare on the boom riser, eliminating the remotely located flare. However, there were concerns with the feasibility of such a flare consolidation, the effects of thermal radiation, and the possibility that system changes would increase the backpressures on the relief devices. Smith & Burgess was hired to review this system.

Case Study: LOPA Action Item Review

Posted by Dustin Smith, P.E. on Feb 1, 2018 5:58:00 PM

The Opportunity:

A recent Layers of Protection Analysis (LOPA) of a cavern storage facility identified several equipment installations requiring safety system upgrades. While the facility management wanted to follow proper review procedures, these proposed mitigation options seemed excessive. As a result, the site hired Smith & Burgess to review the safety systems upgrades to ensure the installations were needed and met regulatory requirements.

Case Study: SIL Design

Posted by Dustin Smith, P.E. on Dec 2, 2017 6:05:00 PM

The Opportunity:

As part of a relief valve study, a competing engineering firm recommended a major United States refinery to replace multiple relief valves and modify the associated piping on a column system in order to mitigate for a higher flare load. The proposed changes would have cost the refinery approximately $300,000. Unsure of the recommendations and associated expenses, the refinery reached out to Smith & Burgess to review the EPC’s findings.

Case Study: Third Party Relief Valve Mitigation Review

Posted by Dustin Smith, P.E. on Nov 1, 2017 6:03:00 PM

The Opportunity:

A major US refinery used a competing engineering contractor to perform a flare and relief systems analysis. Upon completion of the project, the refinery was left with a list of facility upgrades that management deemed excessive. Smith & Burgess was hired to review the relief and flare systems documentation and provide engineering solutions that met corporate and industry requirements.

Case Study: Facility Siting

Posted by Dustin Smith, P.E. on Sep 8, 2017 6:06:00 PM

The Opportunity:

A major United States refinery was recommended to spend $2 Million on a temporary blast proof tent during turnaround from a facility siting study conducted by a third-party contractor.

Case Study: PSM / RMP Refinery-Wide Audit

Posted by Dustin Smith, P.E. on Aug 14, 2017 6:05:00 PM

The Opportunity:

A major United State refinery was proactively ensuring compliance for their PSM Program in preparation for OSHA’s NEP Program. The refinery contacted Smith & Burgess to share best practices on performing PSM / Internal Audits and used this opportunity to train their corporate and site staff to perform future PSM audits.

Case Study: Flare Bid Review Package

Posted by Dustin Smith, P.E. on Jul 25, 2017 6:02:00 PM

The Opportunity:

A major United States refinery was in the process of purchasing a new flare system and needed assistance reviewing the bid package from the vendors. The refinery decided that the system was needed based on the outcome of a facility-wide flare study and flare QRA. The new flare system was specified by an EPC and then bid by a major flare vendor. This refinery heard of Smith & Burgess’ flare design expertise and decided to hire us in order to review their vendor’s design package.

 Safety Knowledge Should be Share...

“It should not be necessary for each generation to rediscover the principles of process safety which the generation before discovered. We must learn from the experience of others rather than learn the hard way. We must pass on to the next generation a record of what we have learned.” - Jesse C. Ducommun, Safety Pioneer
 
As Process Safety engineers and consultants, we believe our unique position creates a responsibility for Smith & Burgess to share our years of accumulated safety knowledge.
