Implementation of a condition monitoring program for high voltage (HV) assets for the Santos GLNG Project

TL;DRAbstract

Electricity supply to Santos’ existing field operations in the Surat Basin is currently provided by diesel and/or gas motor driven generator sets. This has the disadvantages of poor reliability, high diesel costs and the unwanted consumption of gas that could otherwise be sold to market.
\n
\nPart of the Santos GLNG Project includes the ‘electrification’ of the Coal Seam Gas (CSG) fields and processing plants. Electrical equipment such as large power transformers, HV switchgear, HV motors and Motor Control Centres (MCCs) will be installed to power the expanding gas gathering and processing infrastructure. Due to the remoteness of these assets and the critical role they will play in the CSG process, it is essential that they are highly reliable. It is intended to employ condition monitoring technologies to aid in achieving this.
\n
\nA literature review was conducted in order to research current CM technologies applicable to HV plant and equipment. From this, identified
