FEL-II to FEL-III: decision for the use of the FF Technology: Project Manager, Sponsor, Final Client (Operators) Supported by the Licensor Pros: (in 2006) -EPC: reduction in materials & HH, Inteligent Instruments (more

information). -Maintenance: prediction -Advanced Control: indicated by the Licensor- U$ 1MM per year in Profits -Better response (PID´s running in the field) -Accuracy

Cons: -Instruments and Cabling: more expensive -Service: expertise in FF Technology by EPC team -Review in Loop tests: new procedures -Review in Schedule: Commissioning, Loop tests, etc.

FEL-III (FEED) FEED scope FEED deliverables

Before Phase IV:

Generation of “Specific Documents”: MD for FF specs, including Cables MD for EPC contract: Automation Chapter MD for Integrator-Contract, included in EPC scope LD for Specific FF deliverables (documents) by “Detailing Eng.” RL´s for: Commissioning, Loop-tests, Start-up procedures

General Project Criteria: 12 Devices per H1 segment-maximum 10 Devices instaled per H1 segment 03 Field-barriers per H1 segment 12 Spurs= 10 installed + 02 spares Voltage calculation for 12 Devices Microcicle Calculation for 12 Devices 1000ms for Microcicle time(maximum) per H1 segment, indicated by Licensor Acceptable: 02 Control valves per H1 segment Connectors in the Fieldbarrier and Cable-glands in the Instrument ITK-4.5 (minimum) DCS: ABB IIT, Devices: Multiple Suppliers (PETROBRAS Vendor-List)

Control Valve Criticity FF Loop Analisys Report Procedures and Calculations by CENPES Participants: CENPES (MC), Operators, Automation Experts, EPC, Ext.

Consultant. Results: 58% of Loops accepted PID running in the Field (Valve Positioner).

Testing Procedures: Instruments Set-up (in the Bench) DCS parameters, configurated previously, should not modify “bench set-up”:

loss of Certification

Dynamic Test for FF devices “in the Bench”: Procedures consolidated with “Integrator” Reports as Standards for Tests General Criteria: >Cable maximum lengh cut for H1 >Cable maximum lengh cut for Spurs >Simulate each H1, in the bench, with all devices and cables to test Voltage and Microcicle values to certificate each H1 segment >Consolidation of Voltage and Microcicle Memory Calculations. DCS parameters, configurated previously, should not modify “bench set-up”:

loss of Certification

Testing Procedures(Cont): Procedures for Connectorization Connectorization should be performed in a clean enviroment, never in

the field/site. Static test for Cables plus Connectors, in the bench. “Dynamic” test for Cables plus Connectors instaled in Trays in the

field. Loop Tests: Faster, accurate Reports “from the Bench” as a reference to Field results Consolidate: Voltage and Memory Calculations- minumum deviation Use of FF signal Wave Form pictures in the Reports comparing bench

to site values. Composition of a File containing information for each Device in each

H1 segment with all Devices. Acceptance procedure: file to be approved before and after tests.

““JUST ONE CASE”JUST ONE CASE”

Important Aspects: Are EPC´s prepared to support a project in FF(2012)?• Certification for Automation Engeneers • DCS Suppliers are prepared to develop a project in FF? • Very Important: include a FF Certified Integrator in the EPC

Contract. • Interoperability: DCS versus Instrument Suppliers. • Internet: FF Website and Instrument Suppliers Website DCS Suppliers shall “open doors” to other Instrument Suppliers. DCS Suppliers shall “work close” to EPC´s PID running in the Field is not a “Monster”.

And Finally

It was “Just a Case”
