FEED Engineering Services
Let us understand how we can help you
INDSAFE provides FEED Engineering support for industrial projects, helping develop the technical basis, preliminary engineering documentation and design requirements needed to progress from project concept development towards detailed engineering and execution.
Our Front-End Engineering Design (FEED) services can include process engineering, P&ID development, preliminary plant layouts, equipment specifications, engineering documentation and process safety considerations, depending on the project scope.
Through structured design development and coordination of relevant engineering interfaces, we help project teams clarify technical requirements, identify information gaps and prepare engineering deliverables to support project planning, cost estimation and EPC tender preparation, where applicable.
What Is FEED Engineering?
Front-End Engineering Design (FEED) is an engineering phase that develops a selected project concept into a more defined technical design before detailed engineering, procurement and construction.
The FEED phase establishes the design basis, preliminary equipment requirements, process documentation, layout concepts and engineering criteria needed to define the project more clearly. It can also support cost estimation, schedule development, technical risk identification and preparation of EPC tender documents.
The scope and maturity of a FEED package vary according to the project, industry, contracting strategy and client requirements. FEED is not a substitute for the detailed engineering, verification and approvals required for subsequent project stages.
Our FEED Engineering Services
INDSAFE’s FEED engineering scope can be tailored to the facility, project objectives, available inputs and required deliverables.
1. Process Engineering
Process engineering establishes the technical basis for the intended process and supports the development of associated engineering documentation.
Depending on the scope, activities may include:
Process design basis and engineering design criteria.
Process Flow Diagrams (PFDs).
Heat and material balances, where applicable.
Preliminary process equipment sizing and calculations.
Process descriptions and operating philosophy documentation.
Process engineering inputs for P&ID development.
2. P&ID Development and Engineering
Piping and Instrumentation Diagrams (P&IDs) communicate process equipment, piping, instrumentation and relevant control interfaces. During FEED, they help define the process configuration and establish a basis for subsequent engineering development.
Potential activities include:
P&ID development and review.
Identification of process equipment, lines and associated requirements.
Representation of relevant instrumentation and control interfaces.
Identification of process isolation and protection requirements based on available design inputs.
Coordination of process documentation with other engineering deliverables.
The level of P&ID detail depends on the design stage and agreed project requirements.
3. Preliminary Piping and Plant Layout Engineering
Preliminary layout development helps establish the spatial arrangement of major equipment and relevant plant areas before detailed design.
Depending on the scope, deliverables may include:
Preliminary plot plans and equipment layouts.
Initial piping routing and layout development.
Equipment access and maintenance space considerations.
Pipe rack and equipment interface coordination.
Preliminary piping documentation, where required by the project.
Detailed piping isometrics, fabrication drawings, advanced 3D modelling and clash detection should be defined separately where required.
4. Equipment Specifications and Technical Requirements
FEED establishes preliminary requirements for major equipment and associated systems to support engineering development and vendor enquiries.
Potential activities include:
Preliminary equipment sizing and technical evaluation.
Equipment data sheets and specifications.
Identification of operating conditions and utility requirements.
Technical inputs for vendor enquiries and procurement planning.
Review of vendor technical information, where included in the scope.
Final equipment selection and specifications depend on the applicable design criteria, technical evaluations and project approval process.
5. Process Safety Integration
Relevant process safety considerations can be incorporated into FEED to inform design decisions and identify hazards or safeguards requiring further development.
Depending on project requirements and the maturity of the design, activities may include:
Preliminary hazard identification (HAZID).
HAZOP study planning, coordination or facilitation, where agreed.
Identification of process safety design requirements.
Review of relevant isolation, protection and safety-critical design considerations.
Tracking of actions and design changes arising from safety studies.
The required studies, assessment methods and level of detail should be agreed separately. A process safety study does not automatically form part of every FEED package.
6. Engineering Documentation and Project Definition
Engineering documentation provides a consistent basis for the next project phase and records the requirements, assumptions and interfaces established during FEED.
Potential deliverables include:
FEED design basis and engineering criteria.
Preliminary engineering drawings and calculations.
Equipment and line lists, where applicable.
Technical specifications and data sheets.
Engineering deliverables register.
Design assumptions, interface registers and outstanding information lists.
FEED summary report, where required.
The final document list depends on the project scope and agreed level of design maturity.
Typical FEED Engineering Deliverables
The deliverables for a FEED project are defined according to the facility, engineering disciplines involved, available design inputs and intended use of the package.
Typical deliverables may include:
Design Basis and Engineering Design Criteria.
Process Flow Diagrams (PFDs).
Piping and Instrumentation Diagrams (P&IDs).
Preliminary plot plans and equipment layouts.
Preliminary equipment data sheets and specifications.
Preliminary piping layouts and routing drawings.
Utility requirements and utility flow diagrams, where applicable.
Engineering calculations within the agreed scope.
Engineering deliverables register.
Technical inputs for cost estimation and EPC tendering.
Design assumptions, interface and open-item registers.
FEED summary report and recommendations, where required.
Not every project requires all these documents. The deliverables list, review responsibilities and required approval status should be established at the start of the engagement.
Our FEED Engineering Approach
INDSAFE follows a structured approach based on the project objectives, design maturity and agreed scope.
1. Project Requirements and Data Review
We review the available project brief, process information, existing drawings, site data, client specifications and other relevant technical inputs. Missing or conflicting information is identified for clarification.
2. Establish the Design Basis
The applicable design criteria, assumptions, process requirements, battery limits and engineering interfaces are established using the available project information and client requirements.
3. Preliminary Engineering Development
The agreed process documents, P&IDs, preliminary layouts, equipment requirements and other engineering deliverables are prepared or reviewed according to the defined scope.
4. Multidisciplinary Coordination
Relevant engineering interfaces are reviewed to identify inconsistencies, technical constraints, design gaps and outstanding information requiring resolution.
5. Technical Review and Action Tracking
Deliverables are reviewed against the agreed design basis and project requirements. Comments, assumptions, deviations and outstanding actions are documented and addressed through the agreed review process.
6. FEED Package Finalization
The agreed documents are compiled and issued with appropriate identification and revision status to support project evaluation, cost estimation, detailed engineering planning or EPC tender preparation, as applicable.

FEED engineering may include process design documentation, P&IDs, preliminary layouts, equipment specifications, engineering criteria, selected calculations and process safety inputs. The actual deliverables depend on the project scope and agreed design maturity.
What is the difference between FEED and detail engineering?
FEED develops the selected project concept into a more defined technical design and establishes the engineering basis for the next phase. Detail engineering develops the agreed design into more detailed drawings, specifications, calculations and documents for procurement, fabrication, construction or installation, as applicable.
When is FEED engineering required?
FEED is commonly undertaken after concept selection and before detailed engineering and project execution. It can help establish project requirements, improve cost estimation and support EPC tender preparation before major commitments are made.
Does FEED include detailed engineering drawings?
FEED may include preliminary drawings and selected documents developed to the level required for the project. The full set of detailed engineering drawings is not automatically included and should be defined separately.
Does FEED include HAZOP and other process safety studies?
Not automatically. HAZID, HAZOP and other process safety studies may be included, coordinated or supported where specified in the project scope. The required studies and their timing depend on the design stage, available documentation and client requirements.
Can FEED engineering support plant expansion or modification projects?
Yes. FEED can help define the technical requirements for expansions, revamps and modifications to existing facilities. The scope depends on the reliability of existing drawings, verified site information and the extent of the proposed changes.
Does FEED engineering provide a guaranteed project cost or schedule?
No. FEED can provide a stronger technical basis for cost estimation and schedule development, but the accuracy of estimates depends on design maturity, project assumptions, market conditions, execution strategy and the quality of available information.
