• 479MW combined cycle power station, generating since 2000
• Inspection planning and major inspection findings

This case study aims at highlighting how a design error can creep in during construction phase of a power plant and subsequently affect gas turbine operation. The case study discusses elemental sulphur contamination in fuel gas and how not understanding the problem can prolong the time it takes to find a remedial solution, which apparently is quite simple. The case study is well documented with photographs, process data, test reports and costing information.

BHGE’s development roadmap about optimization of Oil & Gas plants against torsional vibration phenomena

• Key features of the TVCS product, including Advanced Torsional Monitoring, Real Time Insights, Industrial Internet Connectivity and Torsional Active Damping.
• Successful stories about TVCS field experiences
• Open discussion with Australian Customers about their field experiences on torsional vibration phenomena

Final aim of this presentation is to enable a common understanding and mitigation action possibilities about torsional vibration phenomena among Australian Gas Turbine Users.

Discuss and review the overall performance of the TTH2O+ water tight (H)EPA filter. Reduce/eliminate water washes completely due to the filters ability to lock moisture out, we will discuss the benefits and savings to plant and equipment using (H)EPA E12 water tight filter media.

• TTH2O+ Filter Overview
• Sustainable DP, filter life extension
• 0% axial compressor losses
• Online/Offline water washes reduced/eliminated completely
• Data comprised from local and global applications with a highlight being the performance through Hurricane Harvey

Following failure and in-situ replacement of Bearing 1 on an 8 MW industrial gas turbine, excessive vibration was observed on Bearing 2 a few months later. This case study describes the vibration symptoms and diagnosis, including a discussion of the circumstances where a machine with tiltpad bearings can experience fluid instability. A bistable vibration phenomenon observed at cranking speed was also observed, and a possible hypothesis is explored. The means to alleviate symptoms and hence maintain production are also discussed.
