Relief Systems Design & Documentation
Our methodology is cost-effective, saving you money while providing you with comprehensive, PSM compliant documentation.
Smith & Burgess has the experienced staff to solve relief systems related problems. We can provide relief systems documentation as required by OSHA either from scratch or update existing documentation. Have other contractors told you that your flare loads are above your existing systems’ capacities? We can review the design to find possible solutions. Trying to confirm if atmospheric release devices meet current standards? Let us help. Our knowledge and methodology allows us to provide value beyond comparison.
Relief Systems Documentation
Smith & Burgess has provided multiple refineries with relief systems documentation. This documentation is critical to achieve compliance with OSHAâs PSM Standard. Relief systems documentation and the update of the documentation may be triggered in any of the following ways:
- Relief systems design documentation â Whether the need is for a single unit or a whole facility, Smith & Burgess has proven experience providing reliable documentation that fits the needs of the facility. We pride ourselves in using reasonable assumptions that meet the industry standards, yet donât burden the owners with excessive concerns.
- MOC based documentation updates â As the facility changes, the relief systems documentation needs to be updated. Smith & Burgess can provide relief systems experts for either temporary or long term assistance in keeping relief systems documentation evergreen as the changes are made.
- Project changes â Large debottleknecking or other projects require relief systems reviews and documentation updates. Smith & Burgess has provided both a check of the FEED contractors work and provided complete relief systems design for processes that are being revamped and/or expanded. Our experts can get every last ounce of protection out of the existing systems allowing a facility to focus funds in the areas that really need the upgrades.
These are just a few of the items that typically trigger documentation updates. Call our experts to find out more ways we can help with all of your relief systems documentation needs.
Atmospheric Relief Device Discharges
Most facilities with large numbers of relief valves have a few that may need further review due to deficiencies in any number of areas. Beyond our expertsâ ability to implement the recommendations in API STD 521, we can provide detailed dispersion modeling and risk facilitation for those valves that need further review. Our experts can also provide a management team with the information needed to make informed decisions on relief devices that discharge to atmosphere.
Flare Load Reductions
Most facilities have expanded over the years and in recent years may have added atmospheric relief device discharges to closed flare systems. Our experts have been called on many times to help a site understand what other contractors mean by âTheir flare is too smallâ. While every system is different and no one can predict what assumptions have been made in pastâ¦ we have found 20% â 40% reductions in the estimated total vapor relief loads to flare systems as compared to the original estimates from other contractors.
What OSHA’s PSM Standard Says
The OSHA PSM standard requires that covered facilities have a documented basis for their relief systems. For additional information on what is expected of relief systems documentation: download a copy of our white paper. Note also that the Action Item Resolution paper provides an in depth look at the regulatory requirements for these items and has the accolade of industry and regulatory bodies. For information on US codes and standards typically applied to relief systems, see our list of typical codes and standards.
Smith & Burgess has on staff experts that are fully trained in relief systems design and documentation methodology. Our knowledge of relief systems can save you money on documentation efforts and installation costs. We will generate fewer concerns and will provide documentation that is compliant with the PSM standard.
