|Design & Engineering:
1. Conceptual Design/Feasibility Study:
ESNZED offers a complete service of design basis with main process parameters defined (overall plant production requirements etc.), some overall block flow diagrams, a preliminary space study to define overall space requirements and finally an overall cost estimate.
(i) Concept Rationalization & Pre-Feasibility:
a) Strategic Business Assessment.
b) Synergy Existing Operations.
c) Site Availability Review.
d) Raw Material & Utilities availabilities review.
e) Technology Requirements.
f) Pre-feasibility & options study.
(ii) Feasibility & Venture Philosophy:
a) Feed & Production Slate.
b) Feasibility Study.
c) Technology Review.
d) HSE/Risk Assessment.
e) Marketing Study.
f) Class 1 cost Est. (+/- 40%).
g) Project Economics.
h) Venture Philosophy.
2. Basic Engineering/Front End Engineering (FEED)
ESNZED support in the development of a well defined design package in order to prove the feasibility and the cost estimate from the Conceptual Design.
Furthermore this is the start up package for Detailed Design (DD). In many cases this package may also be used as a tender package for a Design/Construction Contract.
(i) Design Basis:
a) Process Design Package.
b) Design Basis Memo.
c) Update Project Execution Plan.
d) Class 2 cost Estimation. ( +/- 20%).
e) Update Schedule & Risk Analysis.
f) HSE Issues addressed.
(ii) Basic Design & Appropriation:
a) Basic Design of ISBL & OSBL.
b) Standards & Specifications.
c) Final work Scope.
d) Final Value Engineering.
e) Final Project Execution Plan.
f) Control Schedule.
h) Class 3 cost Estimation. ( +/- 10%).
i) Approved Budget.
3. Detailed Engineering & Construction:
ESNZED provides all discipline engineers looking at piping layouts, electrical distribution boxes, mechanical assemblies etc. Basically everything that is required to actually go and build a plant. That is the detailed engineering stage. For process design remaining work will be limited to verifying that the actual piping layout, the equipment purchased etc is in line with the present process design and incorporate any updates required. Typically procurement of main equipment takes place during the detailed design stage and this requires interaction from the process engineer as well as other disciplines.
(i) Detailed Design & Construction:
a) Design & construction
b) Project Procedures
c) Design & Construction Drawings.
d) MTOs & POs.
e) Material Management Procedures.
f) QA/QC Inspection.
g) Class 4 Cost Estimation.(+/-5%).
h) Final Schedule.
i) Mechanical Completion.
(ii) Close Out & Re-Appraisal:
a) Mechanical & PSSR.
b) Punch List Clearance.
c) Completion & Commissioning Procedures.
d) Project Documents Handover.
e) Close Out Report
f) Performance Acceptance Tests.
