This facility had 15 well slots, but only 10 of these were actually drilled. Process facilities comprised a separator for oil and gas.

After separation, the gas was compressed to increase its pressure and then dehydrated before being transported in a 12-inch pipeline to Ekofisk 2/4 R. The separated oil was pumped through a dedicated 10-inch pipeline to the same destination.

Both oil and gas passed through a fiscal metering station before export to measure the quantities produced.

The platform was originally designed as a combined drilling, production and accommodation unit with a separate flare stack. However, the drilling package was transferred to Ekofisk 2/4 K in 1987 and a new process module installed to handle output from the Tommeliten field 11 kilometres west of Edda.

Production ceased in 1998 and Edda 2/7 C was abandoned.
