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

Summary of Previous Employment.
