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: 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.

 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.
