OPEC has been engaged by CDSCC for the past five years to complete critical maintenance for their backup generation system. Maintenance includes EITs, dispensing equipment service, inspection, and function testing of the diesel delivery system responsible for powering their generators.


In 2020 OPEC was contacted for a critical breakdown. Within moments, staff were reviewing system P&IDs and developing the repair plan. OPEC staff mobilised to site and began critical repairs and system modifications right away. Those repairs are still in operation today.

OPEC technicians revisited the crucial infrastructure to carry out various tasks including: draining the tank, gas freeing, conducting necessary repairs on the tank, performing EIT, and commissioning.
