1 Scope

This Saudi Aramco Engineering Standard (SAES) establishes the minimum engineeringrequirements for proper design, commissioning, and documentation of Instrument AssetManagement Systems (IAMS) installations to be used within Saudi Aramco’s facilities.

2 Conflicts and Deviations

2.1 Any conflicts between this Standard and other applicable Saudi AramcoEngineering Standards (SAESs), Saudi Aramco Materials System Specifications

(SAMSSs), Saudi Aramco Standard Drawings (SASDs), or industry standards,

codes, and forms shall be resolved in writing by the Company or Buyer

Representative through the Manager, Process & Control Systems Department of

Saudi Aramco, Dhahran.

2.2 Direct all requests to deviate from this Standard in writing to the Company or

Buyer Representative, who shall follow internal company procedure SAEP-302

and forward such requests to the Manager, Process & Control Systems

Department of Saudi Aramco, Dhahran.

3 References

4.2 Definitions of Important Terms

Highway Addressable Remote Transducer (HART): A protocol that usesFrequency Shift Keng (FSK) technology to modulate and transmit its bidirectional superimposed digital signal. The digital signal is superimposed on

the 4-20 mA DC current loop in a client-server mode.

Instrument Asset Management System (IAMS): A system composed of

interface modules, a single or multiple PC’s, software options, and selected

add-on applications to help maintain/troubleshoot instruments and increase theiravailability through device diagnostics.

Life Cycle Cost: Total initial construction cost of the system plus the cost ofoperation, testing, inspection, maintenance, administration, etc., through the

expected life of the system.

Proponent: The end-user.

5 Design

5.1 General

5.1.1 The Instrument Asset Management System (IAMS) shall automatically

and continuously monitor the status, events and operating conditions of

the field-connected devices to provide an efficient condition-based

maintenance solution without interfering with the plant control system.

5.1.2 Smart (HART) field devices shall only be connected to the IAMS systemthrough HART interface cards. The use of HART multiplexers shall

only be used with systems that do not offer HART enabled I/O.

Commentary Note:

Applications where HART multiplexers may be used include EmergencyESD and CCS applications.

5.1.3 IAMS system architecture shall be to have one client station in each PIBwhile the main server resides in the Engineering Room inside the CentralControl Room (CCR).

5.1.4 All field instruments diagnostic information shall be available at each

IAMS client station.

5.1.5 Configuration shall be possible at any client workstation with proper

password protection.

5.1.6 Changes at IAMS shall be avoided unless the change is approved thru anMOC process.

5.1.7 Device diagnostics shall be set in accordance with NAMUR NE-107.

5.1.8 Changes downloaded from IAMS into field instruments shall also be

performed in the DCS.

5.1.9 IAMS systems shall comply with all requirements in 34-SAMSS-911.

5.2 Smart ZV Monitoring System (SZVMS)

5.2.1 Testing shall be recorded to enable compliance with the requirements ofstatutory authority and for meeting the required test intervals specified inSAEP-250.

5.2.2 Diagnostic data from the ZV integrated local control station shall beintegrated with the SZVMS as per 34-SAMSS-634.

6 Project Phase Requirements

6.1 IAMS data flow from field devices to client and server stations shall bedocumented as part of the deliverables.

6.2 During the Factory Acceptance Test (FAT), one device from each type fromeach vendor shall be tested to ensure accessibility to device configuration,

calibration, diagnostics and documentation.

6.3 A brief report shall be provided to show what was tested and whether the resultswere successful or not.

6.4 For all valves with Fieldbus and/or HART positioners, valve diagnostic tests

(i.e., signature curves, dynamic error band, drive signal, output signal, sticky

valve and step response) shall be loaded into the IAMS database and verified

during Site Acceptance Testing (SAT).

6.5 The IAMS system shall be installed, commissioned and put into operation before the precommissioning for the field instruments starts. As a minimum,

the following tasks shall be done to achieve this state:

6.5.1 The IAMS database shall be fully populated with the latest device data

for every fieldbus and/or HART device on the project.

6.5.2 The following device diagnostic alarms shall be set as minimum:

1. control valve cycle counter,

2. air supply depletion, and

3. friction band.

For smart ZVs, the partial stroke test reminder shall be set.

6.5.3 Attach or associate the applicable Instrument Specification Sheet (ISS)

to each device.

6.5.4 Attach or associate the applicable Instrument Segment Diagram (ISD) orInstrument Loop Diagram (ILD) to each device.

6.5.5 Obtain approval in writing from the Proponent Representative that theIAMS is fully commissioned and operational.

6.6 Training

A Formal vendor training shall be given to key plant personnel to raiseconfidence and expertise level. Each plant shall then appoint an IAMS

champion who will have ownership of the system and be the focal point for

IAMS activities.
