C-P Systems
RELIEF SYSTEM DESIGN
Managing relief systems in industrial environments requires more than just meeting compliance standards—it means anticipating overpressure risks and safeguarding your team and equipment. You need a partner who understands the intricacies of your process and can create a pressure relief design that addresses gaps in documentation, system complexity, and regulatory requirements, including OSHA 1910.119, API 520/521, and PSM standards. C-P Systems’ relief system design services bring expertise and precision to this process, ensuring your facility is protected, compliant, and built to withstand even the most challenging conditions.

What Our Clients Say
“My experience working with C-P Systems on this project was extremely satisfying. Their level of organization and professionalism was the best I have been associated with and the attention to detail along with the knowledge of the code to get us to the correct results made the project run smoother and saved time by reducing unnecessary rework. The final packages are extremely complete and require little to no in field measurement verification. I try to use them on every project I work on.”

Frequently Asked Questions
What is the purpose of a relief system study?
A pressure relief system study ensures your facility is protected from overpressure events. It evaluates whether your relief devices are properly sized and located to safely handle worst-case scenarios and whether they comply with PSM, API, and ASME standards. We bring clarity to complex relief design challenges with practical, thorough deliverables that help prevent downtime and protect both people and equipment.
Do you provide relief studies for existing systems?
Yes. We routinely evaluate and update relief systems in operational plants, even when legacy documentation is incomplete or outdated, to help ensure compliance to safety standards and improve protection for existing assets.
How do you determine worst-case scenarios for relief sizing?
Our industry experience allows us to quickly hone in on the worst-case scenario so we spend our time efficiently and effectively on what actually matters vs. holding up process design, material orders, or project schedule.
What if we don’t have documentation for all equipment?
If documentation for all equipment missing or incomplete, we can run equipment pressure calculations to guide next steps and specify overall design.
Can you help implement recommendations from a relief study?
Yes. We can carry recommended changes through detailed design with practical, thorough engineering deliverables, including updated P&IDs and piping changes to bring your system into compliance.
