2. Project Description:

2.1 The IEC is required by the NGA (Natural Gas Authority) to perform a comprehensive

asset integrity and condition assessment of the Natural Gas Distribution System inside

its power station by an Independent Inspection notified Body to be able to demonstrate

continued system operation at the design conditions. These assessments shall be

performed individually per specific NG power station.

2.2 The following power stations are included in the scope of work:

GAS Consumers Power Station

Two (2) gas turbines and two (2)

Auxiliary boilers

Haifa

Six (6) gas turbines and two (2) Auxiliary

boilers

Hagit

One (1) gas turbine and one (1) Auxiliary

boiler

Alon tavor

Two (2) steam boilers Reading

Six (6) gas turbines and two (2) Auxiliary

boilers

Gezer

One (1) gas turbine and one (1) Auxiliary

boiler

Tzafit

Two (2) gas turbines and one (1)

Auxiliary boilers and four (4) steam

boilers

Eshkol

Seven (7) gas turbines and one (1)

Auxiliary boilers

Ramat Hovav

2.3 Main Parameters for Gas Consumers.

2.3.1 Gas Turbine

Design Pressure: 25 to 40 bars

Design Capacity: 65,000 – 85,000 m3/hr

Design Temperature: –10 to 50°C

Gaz Pipes: 10" dia. 200 to 1,000 m long.

2.3.2 Auxiliary Boilers

Design Pressure: 1 bar (approx.)

Design Capacity: 900 – 1000 m3/hr


Pipes: 4" dia., 200 m to 1,000 m long (about)

ISRAEL ELECTRIC

CORPORATION LTD.


2.3.3 Steam Boilers

Design Pressure: 5 to 7 bars

Design Capacity: 65,000 m3/hr (approx.)


Pipes: 16" dia. to 24", about 500 m long.

It is considered best practice that the comprehensive asset integrity and condition assessment is

undertaken every four years. The reports generated shall contain a definitive list of integrity

condition monitoring activities in association with the prescribed intervals between these activities.

- Start point: pipes at PRMS outlet.

- End points: flanges entering the skids of the Gas Consumers (Gas Turbines or

the auxiliary boiler or the steam boiler).

d. The NG boundaries are shown on the PFD attached (Appendix 2).

e. The report shall cover all aspect of the design, construction, maintenance, and

existing state of the NG systems.
