The Engineering workflow diagram presented below cover the Process deliverables development for the FEED phase of EPC and PMC projects until the Model Review and is meant to present, at a high level, the engineering execution logic and information exchange required by the different disciplines to successfully execute their work. It is meant to represent the basis of the logic for the engineering execution schedule development for PMC and EPC projects. The readers should acknowledge that various projects may have slightly project-specific contents.
The workflow is meant to demonstrate, at a high level, the Process engineering execution logic and information exchange required during FEED phase by the different disciplines including recommended stages for seeking Fertilizer Companies Operators and Engineers input during design.
The purpose is to:
- Understand engineering workflows for EPC and PMC projects and interrelationships with Client Operators and Engineers, which helps to build Client confidence in engineering effort used for their project.
- Shows the work each discipline must execute and the predecessors for the tasks.
- Helps to make other PMC project members aware of workflow logic and requirements.
- Is useful when informing Fertilizer Companies new staff of the way engineering is done.
Typically, during FEED phase the following deliverables are issued for Process discipline:
- Process Design Criteria
- Scope of project
- Mass and Energy balance (Preliminary)
- PFDs
- P&IDs (Preliminary)
- Design specifications
- Datasheets (Preliminary)
For each deliverables Client input is required at various stages. Engineering workflow diagram presented below underline several recommended stages for seeking Client Operators and Engineers input to improve the deliverables quality and design outcome.
