feed front end engineering design

what is FEED Front end engineering design oil and gas

Front end engineering design example
Every Project and Every Organization is unique. However, as a general FEED may have following key deliverables:

Process
Basis of Design
Process Flow Diagram (PFD)
Process and Instrumentation Diagram (P&ID)
Heat & Material Balance
Equipment List
Instrument Process datasheet
Cause & Effect Diagram

Mechanical
Equipment specifications
Equipment datasheets
Equipment mechanical design
Procurement Enquires for Long Lead Items
Technical evaluation for main equipment

Piping
Plot Plan
3D model (Equipment and main lines)
Piping Layout
Paint specification

Instrumentation & Control
Control system specification
Instruments design datasheet
Systems I/O sizing
Instrument List
Hook-up drawings
Cable routing drawings (main routing only)

Civil & Structure
Soil investigation specification
Underground network drawing (general)
Design specification
Civil works specification (main only)
Drainage network calculation
Concrete/steel standard drawings

Electrical
One line diagram
Electrical consumer list (preliminary)
Equipment specification
Equipment datasheet
Standard design drawings
MTO (preliminary)
Cable schedule (preliminary)

These deliverable are used to generate:

Project Scope for EPC contractor
Overall project cost estimate
Procurement estimates
Project schedule

FEED reduces risks and can give success in detailed design, construction, and commission and plant maintenance.

Study says benefits up to 30% reduction in cost and shorter project execution can be achieved when proper FEED studies performed

Common Outcomes/Concerns can come in FEED
Material or equipment
Availability of Finance
Social or political impacts
Return on Investment
Economic viability
Operational complexity
