Design Process
Concept Design
Design Production to level of providing an outline of both process and building layout required to undertake HAZOP 0
Key Benefits:
- Requirements Capture
- Draft plant item list
- Verification plan against the requirements
- Draft process description
- Outline 3D models
- Establish a design actions tracker
- Process Flow Diagram(s)
- Draft DPD of area or system layouts
- MDDR (Design review)
Scheme Design
The production of a design to a level that provides outline DPDs of the plant and equipment, initial structural sizing, MFDs and MHDs for the process and allows the undertaking of HAZOP 1
Key Deliverables:
- Review and addition of Level 3 requirements
- Mechanical Handling Diagrams
- Defined plant item list
- Outline calculations for key structure members
- SDDRs (Design review)
- Process description
- Draft S&IDD
- Plant 3D models
- Area / System layouts
- MDDR (Design review)
- Updates to Process Flow Diagram(s)
- Draft OIMS (to inc constructability reviews)
- Draft DPDs of Plant items
- Verification plan for this stage against the requirements
- Draft DJR against Engineering Schedule requirements
- Mechanical Flow Diagrams
- Draft Designers Risk Assessment
- Draft radiological classification of areas drawing
- Outline procurement specifications for long lead items
Detail Design
The production of a design to a level that provides mature DPDs of the plant and equipment, detailed MFDs and MHDs for the process and allows the undertaking of HAZOP 2 and procurement activities.
Key Deliverables:
- Review and addition of Level 4 requirements
- Mechanical Handling Diagrams
- Plant 3D models
- Review NODA
- Mature Area / System layouts
- MDDR (Design review)
- Process description
- S&IDD
- DPDs of all Plant items
- Review of shielding requirements against NODA and adjust design to increase/decrease shielding
- Verification plan for this stage against the requirements
- Updates to Process Flow Diagram(s)
- OIMS
- Radiological classification of areas drawing
- Designers Risk Assessment
- Procurement specifications for long lead items
- DJR against Engineering Schedule requirements
- Mechanical Flow Diagrams
- Completed plant item list
- Occupancy data for activities in all controlled areas
- Detailed calculations
- SDDRs (Design review)
