Concept Definition (pre-FEED)

Concept Definition, or pre-FEED

, adds a further level of detail to the option selected at the conclusion of Concept Select to achieve more precise definition, a better cost estimate and, ultimately, a scope of work for FEEED.

The scale of a Concept Definition or pre-FEED phase can vary dramatically depending on the nature of the project. Regardless of scale, the activities in Concept Definition are chosen to address the development’s circumstances and can include:

Process scheme optimisation

Reduction in optionality using targeted studies of particular aspects of design e.g. technology selection

Finalisation of field architecture

Preliminary P&ID development

Layout development

Issue of enquiries for long lead or high cost items

Cost estimating and economic assessment

Project schedule enhancement

Preparation of survey scopes of work, tendering and management of the work

Engagement with other work groups and third parties to reduce uncertainties e.g. drilling, reservoir engineering, tie- ins to other facilities, regulatory authorities, buyers of products.

Development of risk mitigation plans

Project execution plan and contracting strategy finalization

Basis of design update

Commencement of the ESIA process
