SAEP-136
Saudi Aramco Management of
Electric Equipment Obsolescence Program
Program Components
The Electrical Equipment Obsolescence Program was developed in 2003 in response to
a BOE request to measure and track the status of obsolescence of Saudi Aramco
Electrical Equipment. The main objective is to ensure the continued availability of a
safe and reliable power supply system. The Obsolescence Program currently consists of
the following components:
5
•
DATABASE: A Company-Wide database of Electrical Equipment information,
accessible to all Business Lines, Admin. Areas and Departments that will be
maintained in an up-to-date manner as prescribed by this document.
•
CRITERIA: An eight point Obsolescence Criteria and scoring system with
guidelines that are intended to provide an objective measure of obsolescence for
existing Electrical Equipment. The Criteria will be periodically applied using the
database to determine and track equipment obsolescence.
•
REPORTS: Upon completion of the Criteria evaluation, the results will be archived
and obsolescence reports will be generated with flags highlighting specific areas of
obsolescence risks and concerns.
•
FPD PLANNING: Electrical Equipment Obsolescence Reports shall be provided to
Facilities Planning Department (FPD) as an input to the development of the business
case analysis for new project submittals by Proponents, and shall be used for future
updates of the Electrical Master Plan.
Program Description
This section provides an overview of the management requirements of the Electrical
Equipment Obsolescence Database, Obsolescence Criteria, Scoring, and Reporting
Systems.
5.1
Database
The database contains detailed information on the Electrical Equipment for each
Saudi Aramco facility. The database tracks the following equipment types:
•
Low voltage and high voltage Switchgear as defined in 16-SAMSS-502 and
16-SAMSS-504.
•
Low voltage and high voltage Circuit Breakers as defined in 16-SAMSS-502
and 16-SAMSS-504.
•
Low voltage and high voltage control gear as defined in16-SAMSS-503 and
16-SAMSS-506.

•
Outdoor motor controllers, as in 16-SAMSS-507.
•
Low voltage and high voltage outdoor switches, as defined by
16-SAMSS-508 and 16-SAMSS-510.
•
Low voltage Switchboards, as defined by 16-SAMSS-519.
•
UPS systems as defined by 17-SAMSS-516.
•
Battery Chargers as defined by 17-SAMSS-514.
5.1.1
Database Information Gathering
Database contains fields of data originating from the Proponent, CSD,
FPD, MSO, and the Vendor. Each organization will be responsible for
performing its own information gathering.
5.1.2
Database Access
The Obsolescence Database will be shared over the Company intranet to
the assigned Proponent, CSD, MSO, and FPD representatives with
password access.
5.2
Electrical Equipment Obsolescence Criteria
5.2.1
Criteria Description
The Electrical Equipment Obsolescence Criteria consists of 8 individual
criterions, which are questions selected to fully cover all obsolescence
aspects. When scored and summed, they produce an objective measure
of that equipment obsolescence. Additionally, threshold values for each
criterion have been established, those criteria that are at or below the
threshold value will be flagged. These measurements provide for a more
in-depth indication of the condition of the equipment. See Appendix B:
Obsolescence Criteria and Scoring Procedure for a detailed list of the
Obsolescence Criteria and instructions for their use.
5.2.2
Electrical Equipment Obsolescence Criteria Application and Scoring
5.2.2.1
The Electrical Equipment Obsolescence Criteria are to be
scored utilizing the information retained in the database. The
Criteria require careful and deliberate evaluation using the best
information and data available, therefore application of the
Criteria will not be automatic and will require specific
individual scoring for each plant.
Page 6 of 20
Document Responsibility: Electrical Substations Equipment
Issue Date: 16 September 2008
Next Planned Update: 1 July 2009
5.3
SAEP-136
Saudi Aramco Management of
Electric Equipment Obsolescence Program
5.2.2.2
The Electrical Equipment Criteria are to be applied and scored
for each piece of equipment, identified in section 5.1, within
each plant. Each criterion has a 0-10 scoring, with 0 being the
lowest score. Each criterion has a weighting (1.25). The score
multiplied by the weight produces the composite criterion score.
All 8 criteria summed make the Equipment Obsolescence rating.
A rating of 40 or less, out of 100, will be the hurdle rate at which
an item of equipment may be considered obsolete.
5.2.2.3
Additionally, each criteria question is assigned a Flag
Threshold. If the numeric evaluation score is equal to or below
the threshold value a "Flag" is set for that criteria question.
This provides additional indicators as to the condition of the
Electrical Equipment.
Obsolescence Reporting
An obsolescence report will be generated and affected users will be notified
when criteria scoring falls below the threshold score.
5.4
Implementation Plan
The Electrical Equipment obsolescence condition, as measured through this
SAEP, is one of the inputs to developing the business case justification for
Electrical Equipment upgrade or replacement projects. In itself, the result of the
obsolescence measurement does not constitute justification, inclusion or
approval of a project in the Capital Program. Following are general guidelines
that shall be used to plan for obsolete equipment identification and replacement:
6
5.4.1
Obsolete equipment whose failure would constitute a safety hazard shall
be rectified immediately under a BI-19 project, or submitted to FPD for
introduction into the capital plan as a safety priority. These items will be
assigned a ranking of 1.
5.4.2
Projects for the replacement/retrofitting of all other obsolete equipment
shall be submitted to FPD for assessment and potential inclusion into the
capital plan, based on Business Case Analysis.
Responsibilities
Administration of the electrical obsolescence program shall be as follows:
