Feed Phase Engineering Design Integrity

FEED Phase Engineering Design Integrity Workflow

Introduction FEED Engineering Design Integrity Workflow (EDIW) EDIW is AMEC’s best practice guidance to Engineering Managers and supporting personnel for the delivery of technical integrity. It is an ‘aide-memoir’ that highlights the key deliverables and activities throughout the lifecycle of a typical FEED project. FEED is broken into six phases: 1 Scope Definition and Engineering Execution Strategy 2 Commencement of FEED Design 3 Initial FEED Development and Hazard Identification 4 Initial Design Review & Audit 5 FEED Design Approval (AFD) 6 Final Reviews and Feed Report Compilation The workflow shown in the EDIW Road Map illustrates the execution sequence on a generic FEED Project. The vertical columns show activities that can be undertaken concurrently whilst the sequential flow of work is across the Road Map. As the deliverables and activities in each phase are completed, work can transition into the next phase. Situations will arise when work will need to be be done out of sequence, typically to meet a demanding project schedule. Use of the EDIW allows the risks of out-of-sequence working to be identified and the necessary mitigation strategies to be put in place. AMEC’s corporate governance and assurance of Engineering will measure compliance with the EDIW workflow and ensure out-of-phase working is being identified and managed. This document contains a copy of the FEED EDIW Road Map and includes detailed descriptions of the activities, the key engineering disciplines and supporting documentation.
