Aberrant P91 Inspection, Repair and Life Extension

ETD Proposal No: 1558-gsp-prop17

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 'Early Stage Damage Inspection, Repair & Life Extension of Aberrant P91 Components'. This newly launched proposal is aimed at testing some of the NDE techniques, tried and established in the earlier project, on the P91 aberrant microstructures, It is also looking at testing some newer NDE techniques developed since the start of the earlier project, and, also look at new ideas and technologies for the strengthening and life extension of P91 components which have either developed creep damage or contain aberrant microstructures.

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.

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.

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 Power Plant Gas Turbine Compressors’. This study is intended to provide operators of Power Plant Gas Turbines (PPGTs) with information to improve their inspection and maintenance planning in relation to the PPGT 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 PPGT 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

 

 

WELDLIFE - Avoidance of P91 Type IV failure in P91 and P92 Steels

To read the proposal brief please click on the Proposal Image

There was an initial project meeting about WELDLIFE in Surrey, just south of London, during the first half of March 2015. If you still want to be part of this GSP, please email us to register your interest.

ETD hosted a webinar presenting this GSP, on 15 January 2015 at 1600h. To view the webinar recording click here. Note: the recording is password protected - if you wish to access it please email us.

“Type IV” in-service creep cracking at weld heat-affected zones in leading power plant steels, such as P91 and P92, has often been considered to be a costly but unavoidable life-limiting problem.  However, as the GSP Outline shows, recent UK industrial and collaborative research projects indicate that by a) improving the heat treatment, and, b) altering the welding processes, the life of welded components can in fact be improved by a factor of the order of 2 to 3 times by measures that will slow down or prevent Type IV cracking.  This should result in tremendous benefits for the steel producers, plant manufacturers, plant operators and welding companies alike.
 
The preliminary findings, exciting as they are, need to be proven in practical application and demonstrated through model component testing, long term stress rupture/ creep testing data generation, and detailed analyses for long term safe life prediction and assessment. This new GSP is aimed at achieving these objectives. It is encouraging that some of the industry partners involved in the preliminary projects have shown interest in being involved and contributing their knowledge base, experience and test materials.
 
The work programme and the indicative costs shown in the Project Outline are subject to discussion between the potential industry sponsors

We look forward to hearing from you.
