Attendances:

Wasco Gasco EmersonEng. Eng. Eng.

Wasco replaced the old metering system (No. 3 Orifice meter runs 10") with a new metering system includes the following:-

1- No. 3 Ultrasonic Meter Runs 10" class 600 type Daniel.

2- No. 3 Pressure Transmitters & no. 3 Temperature Transmitters.

3- No. 2 Gas Chromatographs type Danalizer.

4- Control Panel with no. 2 FloBoss Flow computers.

5- HMI and printer.

The system architecture are shown in the Function Design Specification

During the period from 13/5/2015 to 22/5/2015 the pre-commissioning and commissioning activities were carried out by Emerson, accepted by Wasco and witnessed by Gasco as follows:-

1- loop check of all field signals .

2- Power on for all devices.

3- The no. 3 USMs were checked using Daniel Meter Link S/W and found healthy (Attachment 1: USMs Health Check reports).

4- The field Transmitters (PTs &TTs) were checked and calibrated successfully.

5- No. 2 Gas Chromatographs were configured and calibrated.

Both GCs are in service and connected to both FCs.

Attachment 2: GCs validation report according to ASTM(Standard Test Method For Analysis of Natural Gas by GC, designation : D 1945-03).

The GCs were powered through Power supply (non UPS) installed in the Control Panel.

6- The Flow Computers were configured and interfaced to all field signals according to wiring diagram, Both FCs Calculations are checked using Kelton Flocalc S/W.

Attachment 3: FCs validation.

an offset is made to adjust the reading values at three different points.

the daily reports of the Gas Flow should be issued from Both FCs.

Interfacing to Gasco SCADA couldn't be done serially using one port for the 2 FCs so it was interfaced by ethernet with 2 ip addresses for the 2 FCs.
