4.1 GENERAL DEFINITIONS

The following words and expressions used in the Specification have the following meanings:

OWNER shall mean STAR Refinery A.Ş. (STAR)

ENGINEER means ÇİMTAŞ.

VENDOR shall mean any part who delivers equipment and materials for

FACILITIES/UNITS

PROJECT means Fixed Fire Fighting system rehabilitation and U-630/640 LPG unit &

Impounding basin area Fire Fighting system rehabilitation of STAR Refinery A.Ş.(STAR) at

Aliağa, TURKEY

FACILITIES/UNITS shall mean the entire facilities, units, and plants where fire fighting

systems to be rehabilitated in conformity with the PROJECT requirements and scope that

ENGINEER meet its liabilities as defined in the agreement on, under, in or through

OWNER’s JOBSITE.

JOBSITE shall mean OWNER’s property land at IZMIR – ALIAĞA, TURKEY on, under, in

or through which the required FACILITIES for rehabilitation of fire fighting systems.

5 REQUIREMENTS

The Hydraulic calculation shall be performed considering the minimum pressure at hose connection points on the fire water manifolds.The minimum pressure at hose connections most remote nozzle is 7 bar (NFPA 24). The pressure and flow required by the system at the point of connection to the water supply system have been verified by Omnicadd HCS 2.3.The results are shown in Calculation Report table. For hydraulic calculation, the following general data has been considered for all calculation: • Minimum Pressure at Hose Connection = 7 bar

• Values “C” for Carbon Steel Pipe = 120 (Table 23.4.4.8.1 of NFPA 13)

• Maximum velocity allowable for Fire Water Mains = 3.5 m/sec.

6 FORMULA AND CALCULATION DATA

6.1 GENERAL CRITERIA

The calculations are performed by a hydraulic calculation software, the procedures described

on NFPA 13 and NFPA 24.

REV 0

ASME-B36.10 ASTM A106 Grade B Seamless pipes shall be installed for aboveground fire

protection systems. Equivalent lengths of the used fittings as given in NFPA 13, are added to

the actual length of each pipe pathway for input into the pressure drop calculation. Pressure

drop due to friction is calculated for each pathway by using the Hazen-Williams pressure drop

method. All pressure drops through each critical pathway leading to a system are added for a

total pressure drop due to friction.

6.2 FORMULA

Friction loss formula is described in item 23.4.2.1.1 of NFPA 13

𝑃𝑚 = 6.05 × (𝑄𝑚

1.85

𝐶1.85 × 𝑑𝑚4.87) × 105

where: Pm = frictional resistance (bar/m of pipe)

Qm = flow (L/min)

C = friction loss coefficient

dm = actual internal diameter (mm)

Input Data

The following requirements has been considered as input to OmniCADD Software.

1. Assumed Terminal Point head is 22712 45424 lpm (126.000 gpm) at 8 bar. In case of fire one

Ambassador Mobile Monitor (6.000 gpm) and 2 (two) Fire Fighting Truck ( 2x 3.000 gpm) shall

be connected to 1 x 12” + 2 x 6” Fire Water Manifold.

2. Maximum velocity in the underground fire water network is 3.5 m/s

3. Hose Streams for one (1) outlet is required flow and pressure 22712 lpm (6.000 gpm) at 7

bar. Two (2) outlets are required flow and pressure 2 x 11356 lpm ( 2 x 3.000 gpm) at 7

bar.Hose Streams for one (1) outlet (12”) is required flow and pressure 11356 lpm (3.000 gpm)

at 7 bar, for two (2) outlets (6”) are required flow and pressure 5678 lpm (1.500 gpm) at 7 bar

Output Data

The following requirements has been considered as input output to OmniCADD Software.

1. Calculated head is 22712 45424 lpm (612.000 gpm) at 7.2 bar.

2. Calculated maximum velocity in the manifold pipes is 5.110.2 m/s
