This project marks the first deployment of GE's ReliabilityMax solution for aeroderivative gas turbines used in LNG applications.

GE has a $US620 million ($A707 million), 22-year contractual service agreement to provide advanced technology services for QCLNG.

As part of the CSA, GE is providing planned and unplanned maintenance of the GE equipment installed at the LNG plant, including 15 PGT25+G4 aeroderivative gas turbines, 28 centrifugal compressors, gearboxes, generators, and all auxiliaries.

The agreement also includes remote monitoring and diagnostic services, as well as reliability guarantees on the equipment.

ReliabilityMax can harvest information from the equipment through the Industrial Internet - a network of technology, data and experts - and uses big data analytics and GE experts to boost asset performance and reliability.

The agreement also calls for GE Oil & Gas to supply monitoring and diagnostics technology that will optimise the plant's availability and lifecycle of parts by utilising remote monitoring services.

"Our ReliabilityMax project with [QCLNG owner and BG subsidiary] QGC is noteworthy because by combining big data and analytics with our expertise as a leading gas turbine supplier, we are able to make long-term reliability guarantees for QGC's Curtis Island generation equipment on aeroderivative gas turbine technology for LNG," GE Oil & Gas Turbomachinery president and CEO Rafael Santana said.

Maintenance activities on the QCLNG power turbines and compressors will take place at GE Oil & Gas facilities at Jandakot in Western Australia and in Italy.
