ASME PSD-1: Integrating Systems Engineering and Plant Design

The draft ASME Plant Systems Design standard integrates systems engineering, risk evaluation, and probabilistic design practices into traditional plant engineering processes. This standard provides a framework through which plant owners, designers, and other stakeholders may execute projects in a manner that minimizes errors and omissions in the design process and produces optimal cost and schedule outcomes for its users. Integration of classic systems engineering processes into plant design provides a uniform framework for communicating design requirements, design information, and acceptance criteria throughout the lifecycle of a plant design project. Traditional plant design processes emphasize the use of separate engineering disciplines, which often create information silos that cause errors and omissions in design. The use of a systems engineering process ensures that the plant, its systems, and its infrastructure are designed holistically and consider all requirements for productivity, safety, and the plant lifecycle. This paper provides an introduction and overview of the Systems Engineering and Design Integration (SEDI) portion of the new standard that is targeted for publication in 2025.
