Detailed Engineering Design
Detailed Engineering Design: Finalizing equipment and pipe sizing, hydraulics, and plant 3D model
In process industry, the detailed engineering stage is a critical phase in the process design journey, where the final design and specification of all equipment, piping, and instrumentation are completed. This stage aims to finalize equipment and pipe sizing, and hydraulics and develop a comprehensive 3D model of the plant.
Detailed design progresses through several stages. Initially, with no purchases made and limited vendor data, there is room for adjustments. Subsequently, HAZOP and SIL sessions are conducted to challenge the design and ensure system safety, leading to potential modifications. As vendor data is received, it is incorporated into the design, with limited scope for further changes.
Objectives:
Common deliverables:
Cost Accuracy:
Flexibility to Modifications:
Low flexibility, as changes can impact project costs and timelines
The detailed engineering stage requires close collaboration among the project team, equipment vendors, construction contractors, and other stakeholders to ensure that the final design meets all technical, safety, and regulatory requirements. The resulting deliverables serve as the foundation for procurement, construction, and commissioning activities.
With a focus on finalizing equipment and pipe sizing, hydraulics, and developing a comprehensive 3D model of the plant, the detailed engineering stage sets the stage for a successful construction and startup process.

Objectives:
- Finalize sizing equipment and pipe in addition to hydraulic checks
- Incorporate the final data from vendors
- Develop a comprehensive 3D model of the plant
- Ensure that the final design meets all technical, safety, and regulatory requirements
Common deliverables:
- Final Piping and Instrumentation Diagram (P&ID)
- Verified equipment and instrument data from vendors
- Piping isometrics
- Completed 3D model
- Detailed construction schedule
Cost Accuracy:
- Budget variance of ±0-10%, depending on the project phase
Flexibility to Modifications:
Low flexibility, as changes can impact project costs and timelines
