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.

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.

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.

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.

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.

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.

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.

In order to meet the minimum corporate and regulatory requirements, a major United States refinery was implementing a Flare Gas Recovery Unit (FGRU) and needed assistance to ensure that the proposed equipment was suitable for their location. The EPC company selected for the project was skilled at refinery greenfield and upgrade projects, but had limited experience with complex flare systems. Smith & Burgess was hired to provide owners with an engineering review of the detailed engineering package prior to final acceptance and construction.

After a routine preventative maintenance inspection, a refinery found that a major flare header was in need of replacement. This header connected two large sections of the refinery, and the management feared that a majority of the facility would need to be shut down to safely replace the header. The site hired Smith & Burgess to perform a Flare Header QRA to determine the minimum amount of necessary shutdowns in order to safely perform the line replacement. The Flare Quantitative Risk Assessment used load probabilities to determine the likelihood of various events, should a power failure occur.
