This project is feasibility only and will undertake a desk top study to investigate existing techniques for the determination of Remaining Useful Life (RUL). Existing asset trend data will be used for the evaluation of methods and algorithm’s to establish the relevance to National Grids Compressor fleet (including gas generator, power turbine and gas compressor). Evaluation information includes;

• 'Alert'* condition monitoring system historic data for all compressors

• Existing published research papers on the subject

  *'Alert' monitors all compressors and is a flexible on line monitoring system providing

• Performance monitoring

• Emissions monitoring

• Energy management

• MTBF and availability tracking

Techniques to determine RUL are used in other industries, however this approach is new for NGGT and the application to a compressor fleet would be the first in the UK. The application will explore how best to easily incorporate individual compressor unit criticality. Thus achieving optimum maintenance regime; which may lead to potential cost savings and providing a better service for our customers.

Benefits

The project will deliver a report evidencing available options have been identified, investigated, evaluated and reasoned recommendations made as to their applicability to resolve the identified business problem.
