There isn't a single, universally mandated "standard" for FEED deliverables. The scope and detail of FEED deliverables vary widely depending on the project's complexity, industry sector, client requirements, and regulatory environment. However, there are common and minimum deliverables generally expected from a FEED stage.Here's a breakdown of the minimum deliverables, categorized for clarity, and a discussion of where to find guidance

Minimum FEED Deliverables (Categorized):

1. Process & Basis of Design



Basis of Design (BOD) Document

This is arguably the most crucial document. It outlines the fundamental assumptions, design philosophies, codes & standards, and acceptance criteria upon which the entire project is based. It needs to be as complete as possible to ensure accuracy during the detailed design stage.

Process Flow Diagrams (PFDs)

Simplified diagrams showing the main process equipment and flow streams. This includes mass and energy balances.

Piping and Instrumentation Diagrams (P&IDs) (Preliminary)

Show the layout of the proposed piping, equipment, and instrumentation. Usually at a preliminary level indicating basic control loops and safety devices.

Process Description

A written narrative explaining the process, including operating conditions, control strategies, and potential issues.

Process Simulation Reports

Results from process simulations used to model and optimize the process design.

Equipment List (Preliminary)

A list of all major process equipment, including preliminary sizes, capacities, and material specifications.

Utility Summary

Overview of utility requirements (electricity, water, steam, compressed air, etc.).

Technology Licensing Agreements (if applicable)

Details of any licensed technologies being used in the process.

2. Equipment & Mechanical



Equipment Data Sheets (Preliminary)

For major equipment items (pumps, compressors, vessels, heat exchangers), outlining key parameters and specifications.

Mechanical Equipment List

Including specifications and ratings.

Materials Selection Report

Specifies the materials of construction for different parts of the plant based on corrosion resistance, process conditions, and cost.

3. Piping & Layout



Plot Plan (Preliminary)

Shows the overall layout of the plant, including equipment locations, access roads, and safety zones.

Piping Layout Studies

Preliminary piping layouts to identify potential clashes and optimize piping routes.

4. Instrumentation & Control



Instrument List (Preliminary)

A list of all instruments, including type, range, and location.

Control Philosophy

A document outlining the overall control strategy for the plant.

Safety Instrumented System (SIS) Philosophy (Preliminary)

Outlines the safety functions and requirements for the SIS.

5. Electrical



Single-Line Diagrams (Preliminary)

Shows the electrical power distribution system.

Electrical Load List

Lists the electrical loads for all equipment.

6. Civil & Structural



Geotechnical Report

Provides information about the soil conditions at the site.

Foundation Design Criteria

Specifies the design requirements for foundations.

7. Health, Safety, and Environment (HSE)



Hazard and Operability Study (HAZOP) Report (Preliminary)

Identifies potential hazards and operability problems.

Environmental Impact Assessment (EIA) (Preliminary)

Assesses the potential environmental impacts of the project.

Safety Philosophy

A document outlining the safety principles and practices to be followed.

8. Cost Estimation & Economics



Capital Cost Estimate ( +/- 10-15% accuracy)

A detailed estimate of the total cost of the project. This is a key deliverable.

Operating Cost Estimate

An estimate of the ongoing costs of operating the plant.

Economic Analysis

Includes Net Present Value (NPV), Internal Rate of Return (IRR), and payback period calculations.

9. Project Management



Project Execution Plan (PEP) (Updated)

Describes how the project will be managed, including organization, roles, responsibilities, and communication protocols.

Project Schedule (Level 2 or 3)

A detailed schedule outlining the key milestones and activities.

Risk Register

A list of potential risks and mitigation strategies.

Procurement Plan

Describes the strategy for procuring equipment and materials.

Quality Assurance Plan

Outlines the quality control procedures to be followed.

Where to Find Guidance



Client Specifications

The client's specifications are the primary driver. They will often dictate the required deliverables, level of detail, and formats.

Industry Standards



ISO Standards

ISO 15926 (data model for process plants) can inform data management practices.

API Standards

The American Petroleum Institute (API) publishes standards relevant to the oil and gas industry (e.g., API 520, API 610).

ASME Standards

The American Society of Mechanical Engineers (ASME) publishes standards for pressure vessels, piping, and other mechanical equipment.

IEC Standards

The International Electrotechnical Commission (IEC) publishes standards for electrical and electronic equipment.

Company Standards

Engineering companies often have their own internal standards and procedures for FEED studies.

FEED Contractor Experience

A reputable FEED contractor will have experience with similar projects and will be able to advise on the appropriate level of detail for the deliverables.

Project Size and Complexity

Larger and more complex projects will require more detailed FEED deliverables.

Regulatory Requirements

Local and national regulations may require specific deliverables, such as environmental impact assessments and safety studies.

Important Considerations



Level of Detail

The level of detail required for each deliverable will vary depending on the project. FEED is about defining the project, not doing detailed design.

Iterative Process

FEED is an iterative process. Deliverables are often updated and refined as the design progresses.

Data Management

Consider how data will be managed and shared between different disciplines and stakeholders. Using a common data environment (CDE) can improve efficiency and reduce errors.

Collaboration

Effective communication and collaboration between the client, FEED contractor, and other stakeholders are essential for a successful FEED study.

Purpose of FEED

Remember the purpose of FEED: to define the project scope, technical requirements, cost, and schedule with sufficient accuracy to enable a final investment decision (FID). The deliverables should support this goal.

In summary, the "minimum" is defined by what is necessary to accurately define the project for the next stage, detailed design. Always start with the client's requirements and then supplement with industry best practices and standards. Flag for review
