ETD's Invitation to Join New & On-Going Group Sponsored Projects (GSPs)

In response to the needs of the international industry, ETD Consulting regularly launches new multi-client projects which are open to all.

ETD has excellent expertise through its in-house R&D, plant service/technical consulting and project management experience and links with plant manufacturers, plant operators, service providers and researchers from around the world. The company is thus in an ideal position to conduct such projects on behalf of project partners/sponsors and bring together plant experience from best run plants and the latest technology development in Europe, Japan, USA and elsewhere.

The benefit of joining these GSPs, in which costs are shared, is that each participant gains the data and results of the whole project at a fraction of the total project cost. All work is carried out by ETD and its expert staff/ consultants but the sponsors determine its direction.

Failure Investigation and Root Cause Analysis (RCA) of a Gas Turbine

ETD recently completed a project on Failure Investigation and Root Cause Analysis (RCA) of a Gas Turbine for a Middle Eastern Power Plant.

The client urgently decided to replace the damaged GT compressor parts. During disassembly of the GT compressor casing, further, similar damage was observed at other compressor rotor stages and to the stator vanes.

ETD were requested to provide a quotation to perform complete Failure Investigation and Root Cause Analysis (RCA) for the above damaged parts, which have been removed from a Gas Turbine.

The scope of the work carried out included:

  • Applying appropriate tools and methodologies to determine the root cause of the failures/ damages.
  • Detailed analysis and discussion of the failure investigation & RCA findings.
  • Conclusions and recommendations based on the findings of the above investigation.
  • A report of the RCA study results to include recommendations for any mitigating actions to be taken by the plant operator for continued operation of their GTs.

Investigation of Pitting Damage to Compressor Vanes of 13E2 Gas Turbines

ETD recently completed a project on Investigation of Pitting Damage to Compressor Vanes of 13E2 Gas Turbines.

The following samples were supplied by the client for analysis by ETD:

  • Two compressor vanes stage 5 (with pits);
  • Particle samples collected from the GT compressor inlet.

The study included:

  • Visual / macroscopic examination of the general surface condition and the pitting damage on the samples;
  • Microscopic examination of the general surface condition and the pitting damage on the samples.  Metallographic sections of the damaged areas were prepared in order to examine the size, shape and roughness of the pits, which helped to differentiate between corrosion pitting and impingement damage;
  • Chemical analysis of deposits on the component surfaces and inside the pits – Energy Dispersive X-Ray (EDX) analysis of deposits was carried out in a Scanning Electron Microscope (SEM).  This analysis confirmed the presence of any corrosive contaminants such as chlorine and sulphur;
  • Chemical analysis of particle samples collected from the GT compressor inlet;
  • Identification of the damage mechanism (pitting corrosion or solid or liquid impingement damage) based upon the findings of visual examination, microscopy and chemical analysis;
  • Hardness testing to check the mechanical condition of the vane components;
  • Identification of potential causes of the damage and, if possible, the source of contaminants that have contributed to the damage;
  • A report on the investigation of pitting damage, including (i) analysis of the risk of continuing to run the GT with the observed level of pitting damage on the vanes, and (ii) recommendations for remedial actions that may be possible to avoid or minimize the risk of pitting damage to the GT units.

Launch of a New Group Sponsored Project by ETD "Reliability Issues with Gas Turbines Operating in Baseload and/ or Cycling Modes"

ETD Proposal No: 1475-gsp-prop16

To read the GSP Outline please click on the Proposal Image.

ETD has launched a new proposal for a Group Sponsored Project. The proposal is entitled ‘Reliability Issues with Gas Turbines Operating in Baseload and/ or Cycling Modes’. The overall objective of this project is to ‘identify issues with the operation of open (or simple) cycle and combined cycle combustion turbines and provide information, methodologies and guidance on ways to address reliability and performance problems’. ETD will therefore perform a detailed evaluation of the technical factors and issues that impact the performance of a range of combustion turbine models, including impacts of a range of operating conditions both for base load and cyclic operation. ETD has a good background in this as it has carried out similar work for its clients in North America and Europe. As this is a Group Sponsored Project (GSP) costs are shared between a number of sponsors so each pays only a fraction of the total project cost.

Launch of a New Group Sponsored Project by ETD "Protection & Preservation of Compressors in Gas Turbines"

ETD Proposal No: 1471-gsp-prop16

To read the GSP Outline please click on the Proposal Image

ETD has launched a new proposal for a Group Sponsored Project. The proposal is titled ‘Protection and Preservation of Industrial Gas Turbine Compressors’. This study is intended to provide operators of Industrial Gas Turbines (IGTs) with information to improve their inspection and maintenance planning in relation to the IGT compressor, and to enhance the economics of plant operation. This will allow them to target improvements and optimize expenditure on related aspects of their plant Operations and Maintenance. Such optimization can potentially save plant operators $millions, in terms of improved output and thermal efficiency, as explained in the proposal. This idea comes from the problems faced by some ETD clients, who have experienced damage and degradation of their IGT compressor.

As this is a Group Sponsored Project (GSP) where the project costs are shared between a number of sponsors, the fee for participation in the project is only a fraction of the full project cost. If you would like to obtain a detailed proposal, or would like to discuss options to join this Group Sponsored Project, then please don't hesitate to contact us
