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: Wellhead Gathering System Overpressure QRA

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

The Opportunity:

A review of the “overpressure protection plan” for a wellhead gathering pipeline found that the potential for “multiple simultaneous well shutdown system failures” had been overlooked. The flowing pressure on the inlet to the well choke valve exceeded the allowable pressure in the gathering system. If multiple well safety systems failed, there would be an unacceptable potential for large-scale loss of containment. A Quantitative Risk Assessment of the entire system was needed to determine if the existing overpressure protection system, as a whole, met corporate and regulatory requirements. Initially, the protection plan suggested additional shutdown hardware and increased testing frequency. Smith & Burgess was hired to review this system.

Spring Loaded Relief Valve Details: Valve Internals

Spring Loaded Relief Valve Details: Valve Internals 

A spring loaded relief valve is used in many applications to protect the over pressurization of vessels, pipes and containers. Conventional and balanced bellows relief valves are examples of spring loaded relief valves. Codes and standards like ASME, API,and ISO (to name a few) require that these relief valves are sized to have a relieving capacity that is sufficient to maintain the integrity of the system by preventing the internal pressure for exceeding the design limits. In general, the relief valve is designed and selected by the relief systems designer to meet process-engineering 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: Gas Plant Detailed Relief System Design Review

Posted by Dustin Smith, P.E. on Sep 1, 2017 6:04:00 PM

The Opportunity:

A recent audit of a “rebuild” design package for a major Asian gas plant identified that the EPC may have failed to follow company or industry standards. The owner needed an engineering review of the entire facilities’ relief systems designs prior to their start up in two months. Any deficiencies in company or industry standards needed to be addressed prior to the facilities’ start up.

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.
