This project will develop a new methodology to refurbish the bushing oil in situ, and will demonstrate on site. None of this work is possible at the moment, and will enable the wider associated cost of bushing proceedures to be greatly reduced.

To establish an alternative and cost effective refurbishment that creates life extension and remove the requirement to undertake any asset replacement. This will enable BOCBs to continue in service beyone their original design life.

  • A trialled procedure for in-situ bushing replacement

  • A methodology for in-situ bushing refurbishment

  • A business implementation procedure.
