ולידציה - Design Specification - DS The Design Specification -DS is part of the validation documentation that provides information necessary to complete the design of the project. This document covers only the DCS side and integration with ELT-GHS-150-T3 Gas Heater skid DS Content The DS is usually structured in a relatively standard fashion, with predetermined chapters and sections, where the final contents are tailored according to the type and size of the system under validation. :The main chapters and sections of this DS are Hardware Specification Wiring and Electrical Cabinet Drawing Communication and Network Design Other Documentation ProfiBus Monitoring Values List Running Logic Alarms List Alarm Response Disaster Recovery Programming Design Appendixes Hardware Specification .This section defines the required I/O allocation, according to the wiring diagram document No. P09204-020 Rev2, and 35800SIS0-N0 8 digital inputs 1 digital outputs ProfiBus connection Wiring and Electrical Cabinet Drawing :This section lists the following design information New Electrical drawing is not needed :All I/O should be named in a standard fashion, i.e., XXXX-YYY-ZZZ, where XXXX - 4 prefix letters which indicates the containing system; in this case, the system is PRMS .YYY - indicates the instrument type according to Siemens naming standard – document no ZZZ - indicates the serial continuing number . Siemens Engineering file update is needed in Chapters18C 18D 18E. Other chapters should be examine and discussed in the FRS .BOP PLC must be stopped during the wiring and ProfiBus module installation. Dalkia should be supply with time table Communication and Network Design :This section lists the following design information .The communication used in this project is Profibus .The Profibus communication protocol and wiring design will be provided by Siemens .Siemens Engineering file update is needed. All communication and network chapters should be updated Communication and Network Design Siemens Engineering file "stand alone skids and instruments" chapter should be update; all Heater manuals and instructions should be attached to this chapter.

Heater valve position V102 is open. Heater bypass valve V103 is closed. DCS 10EKA01CF001>1500m 3 h (indicating that at list one of the gas turbines is on). DCS 25Barg<10EKA001CP001<45Barg (Gas pressure operation range). All Heater trips are acknowledged and cleared. Operator pressed "Start" from DCS. Alarms List All alarms from profibus Alarm Response Holding/Restart Logic No alarm response from the DCS. Disaster Recovery Perform stop operations as in paragraph Power shut down Compressed air supply shut down Programming Design AS (Automation system – PLC) that will be programmed in this integration will be BOP. The synoptic screen will be programmed and be added to the PRMS screen, as described in Appendix 1 – Synoptic Screen. All instruments, EG valves and transmitters, will be created according to Siemens standards. All instruments will be set to READ ONLY, except the START and STOP buttons. Appendixes The DS appendixes present examples of design drawings. Appendix 1 – Synoptic Programming Design. Appendix 2 – Chapter 18E BOP Example of Electrical Drawing (to be updated) Appendix 3 – Example of Network Drawing (to be updated)
