Current Position at CWA
External Consultant with CWA Oil & Chemical
Department. Highly experienced petroleum chemist; extensive experience of oil
contamination incidents and quality disputes.
Key Qualifications
- Over 30 years experience in fuels and
lubricants analysis, testing and research.
- Invented a rapid test to predict the storage
stability of middle distillate fuels and developed a test kit for MOD and commercial use.
The test is now published as standard methods IP CP/2000 and ASTM D6748-02a.
- Planned and co-ordinated a research programme
investigating sudden oil filter blockage in aircraft turbine engines. Determined the
chemical causes of the filter blocking sediment; developed a method of assessing the
vulnerability of specific engines to filter blocking to enable planned engineering
improvements to be implemented.
- Designed, developed and ran training courses on
fuels and lubricants analysis
