Pressure Relief System Design and Evaluation

Maximize Safety and Compliance

Pressure Relief Systems are crucial for ensuring safety and preventing the potential consequences of equipment overpressure and loss of containment. At Cognascents, our experienced engineers specialize in Pressure Relief System Design and Evaluation for the assets and facilities of various industries, including oil and gas upstream (onshore and offshore), midstream, downstream (refining), and chemical. We follow recognized industry standards such as API-520, API-521, and API-2000, in addition to adhering to recognized engineering best practices within the industry.

Why are Pressure Relief Systems needed?

Pressure Relief Systems serve as the final line of defense against equipment overpressure and the subsequent risks associated with loss of containment. When process conditions exceed safe operating limits, Pressure Relief Systems come into action to protect equipment, personnel, and the environment from potential harm.

The importance of Pressure Relief System Design and Evaluation is recognized by regulatory bodies, including the Occupational Safety and Health Administration (OSHA). OSHA’s 1910.119 Process Safety Management mandate, established in 1992, explicitly defines Pressure Relief System Design and design basis as critical components of process safety information. This underscores the significance of implementing effective Pressure Relief Systems to ensure compliance and mitigate hazards.

What is Involved with Pressure Relief System Design and Evaluation?

Pressure Relief System Design and Evaluation encompasses a comprehensive set of activities aimed at creating reliable, compliant, and efficient systems. Our services include:
  • Definition of Design Basis and Overpressure Scenarios
    Our experts will gather relevant process information to define or verify the design basis of the system, including the Maximum Allowable Working Pressure (MAWP). We will identify potential scenarios that can lead to overpressure of the system, such as equipment failure, process upsets, or blocked flow.
  • Relieving Rates
    We will conduct a thorough evaluation to determine the appropriate relief device type and size based on the identified overpressure scenarios, upset conditions, and system requirements.
  • Hydraulic and Sizing Calculations
    Our team will perform accurate hydraulic calculations to determine the sizing requirements for the relief device. These calculations will consider various factors, including flow rates, fluid properties, equipment dimensions, and system configurations.
  • Design Basis Documentation
    As part of our service, we will meticulously prepare and provide documentation that includes relief system datasheets, calculations, and design specifications. This documentation will encompass detailed analysis, such as flare radiation analysis, dispersion modeling, and evaluation of flare system design.
