Please confirm that local air quality management regulations allow only the use of DF#1 fuel in order for this section to apply.

The requirements of 4.11.1 shall not apply to engine-driven pumps for which engine cooling water is taken from the discharge.

Confirmed. Cooling water for the engine and gearbox are taken from the pump discharge. Please refer to Calculation Worksheet.


Noted, we will offer an Option for a plate and frame engine heat exchanger, but from our experiences with CABGOC, including our current SNX Project and past Tombua Landana, South Nemba, North Nemba, N'Dola, etc., the engine manufacturers' standard heat exchangers have been preferred. Also please note that if a standard UL Listed engine is to be supplied, Caterpillar's standard shell and tube heat exchanger will be included.

We intrepret this as applying where an enclosure is provided in our Scope. If desired, an Optional Enclosure can be offered.

In event of a failure of the varible speeds control system, the engine shall be fully functional with the governor
