OBEN GAS DEVELOPMENT PROJECT

Chapter Two Project Justification
2.10 Operations Philosophy
A summary of the operating philosophy is as follows:
- The engineering scope must satisfy the specifications stipulated by WAGP GSA.
- The gas supply operating costs must stay within the current range with potential to reduce further in
the near future.
- The manning level shall be --------
- There shall be relatively little incremental in workforce. Where feasible, automation should be
introduced to reduce the operating costs.
- Computer Aided Operation (CAO) and Information Technology (IT) links shall be in place to fulfill
WAGP GSA stipulations on data acquisitions and transmission.
- The facility shall be controlled from the plants’ control room.
- SPDC shall be responsible to provide gas supply to specifications in quantity and quality at delivery
points at ELPS.
2.10.1 Maintenance Philosophy & Strategies
The philosophy is to safeguard technical integrity of the facilities and ensure the designed availability is
achieved cost effectively within the constraints of safety, environmental protection, production plans and
statutory requirements over its life cycle.
To deliver the required gas at a more stringent specification, technical integrity must be improved and
maintained. The approach shall be Total Reliability Centered Maintenance that encompasses the
process reliability and people reliability. This shall aim at increasing plants’ reliability and drive down
cost.
To achieve the above objectives, the following strategies shall be deployed:
• To design-out maintenance to ALARP
• Standardise new equipment design across the locations
• Select reliable and low maintenance equipment
• Use Reliability Centred Maintenance (RCM) to support the designed availability
• On-line condition monitoring of key equipment, where cost effective.
• Use SAP-PM to record and monitor related activity, system, equipment availability and reliability
• Use E-SPIR to achieve spare availability.
Spares
Commissioning, insurance and initial 2-year operating spares shall be, where applicable part of the
project deliverables. E-SPIR will be prepared for materials and equipment that are being introduced to
SPDC inventory. These include purpose-built calibration and repair tool kits. Input from the Corporate
Discipline Maintenance Team should be solicited.
