4.1 Project description

IEC is the owner and operator of two (2) existing offshore fuel pipelines in

proximity of Eshkol power station. The pipelines supply distillates (light/refined

fuels) and fuel oil (heavy fuels) from two Multi buoy mooring berths (MBM)

located about 1.8 km offshore. Due to proximity to the new Break water (LBW) of

"Hadarom" port, both MBM systems are planned to be relocated, as a results,

the pipelines planned also to be re-routed. Additional fuel oil pipeline will be

designed for future installation.

4.1.1 Following is a short description of the existing pipeline systems:

o Southern MBM connected to a steel pipeline of 16" diameter that used for

loading and unloading tankers of distillates products (refined fuels), hereinafter

called "Southern MBM". The 16” steel pipeline was partially re-routed and a new

pipeline was installed at 2015 as “temporary pipeline”. The southern MBM berth

is located about 300 meters to the north from a new Lee Breakwater (LBW) of

the new "Hadarom" port that is under construction by the Israeli Ports Company

(hereinafter called "IPC").

o Northern MBM connected to a steel pipeline of 24" diameter that used for loading

and unloading tankers of fuel oil (heavy oils), hereinafter called "Northern MBM".

The 24” pipeline was installed at approximately 1959. The northern MBM berth is

located about 1100 meters to the north from the southern MBM.

o Both steel pipelines of the MBMs are terminated onshore in a concrete pit

located inside IEC's Eshkol power station.

o The fuel pipelines at the area near the shore crossing are planned to be covered

under the LBW of the new port.

4.1.2 Following is a short description of the proposed modifications to the existing

systems (MBM berths side and shore crossing side, separately):

4.1.2.1 Relocation of the MBM berths (Berths side):

o As a result of previous nautical risk assessment study performed by IEC, it was

decided that the existing southern MBM berth shall be relocated and shifted by

530m toward the north direction in order to increase the safety distance from the

new LBW. As a result, and in order to save also a safety distance between the

MBM berths, the relocation of the southern MBM berth implied that also the

northern MBM berth location shall be shifted by approximately 750m on the

north-west direction. The sea depth at the new position of the southern MBM will


B - 4

be approximately 18.5m. The sea depth at the new position of the northern MBM

position will be approximately 22m.

o The new pipelines system will include new MBM systems and subsea manifolds

in the new locations. The Northern MBM will serve the 24" fuel oil pipeline, and

the Southern MBM will serve two pipelines 16" (distillates) and future 24" (fuel

oil).

4.1.2.2 Modifications of the pipelines after MBMs relocation:

The new configuration of the pipelines will contain three pipelines (instead of

existing two pipelines) as following:

o One new steel pipeline for fuel oil of 24" diameter routed from the new location of

the Northern MBM, crossing perpendicularly the LBW and running in a concrete

conduit in the area of the LBW up to the shoreline. The pipeline planned to be

routed onshore up to the power station.

o One new steel pipeline for distillates fuels oil of 16" diameter will be installed

using existing section of the "temporary 16" pipeline" to form complete distillates

pipeline from the new southern MBM up to the LBW. The pipeline will contain

new section of 16" diameter with 530m long routed from the new location of the

Southern MBM up to the existing "temporary" offshore end of the 16" pipeline.

Additional new section will be installed from an existing offshore bend (closest to

the shore line) on the 16" pipeline routed offshore and crossing the LBW in the

same area of the 24" fuel oil pipeline. The pipeline after crossing planned to be

installed in the same concrete conduit in the area of the LBW up to the shoreline,

then running onshore up to the power station.

o One additional steel pipeline for fuel oil of 24" diameter will be completely new

pipeline will be designed and may be installed in future. The pipeline will be

routed from the new Southern MBM, crossing the LBW at the area of the other

pipelines and planned to run in the same concrete conduit in the area of the LBW

up to the shoreline, then running onshore up to the power station.

4.1.3 Considering the above, IEC is seeking to hire engineering services of a

competent and experienced offshore engineering contractor to provide the

engineering works for the new pipelines system and the related changes as

10.3.1 Waves:

The statistical analysis of waves at Ashdod during the considered 19

hydrographic years (01.04.1992 – 31.03.2011) shows that:

• The dominant direction is WNW. Approximately 51% of the annual waves come

from this direction.

• At the recording buoy location the extreme wave height with 50 years return

period is about 7.2 m, with 100 years return period is about 7.6 m, with 200 years

return period is about 8.0 m.

• In deep water, the extreme wave height with 50 years return period is about 8.1

m, with 100 years return period is about 8.7 m, with 200 years return period is

about 9.2 m.

• The total number of storms was 91.

• The average number of storms per year is ~5, the minimum is 2 storms per year

and the maximum is 9 storms per year.

• Three major storms with Hm0>6.5 m occurred on December 2002, January 2008,

and December 2010. The highest significant wave in deep water was Hm0 =6.93

m (20.12.2002). The highest waves propagate from the dominant direction

WNW.

• The average storm duration is about 47 hr.

• The longest storm duration was approximately 100 hr and the shortest storm

10.3.2 Winds data to be considered for the design:

It should be noted that the statistical analysis is based on 10min wind time

series, thus, could not be applied for analysis of wind gusts. The statistical

analysis of winds in Ashdod area shows that:

• Approximately 90% of annual winds, 86% of winter winds and 93% of summer

winds are light (Wind speed less than 6 m/s). About 9% of annual winds, 12% of

winter winds and 7% of summer winds are fresh (Wind speed between 6 m/s

and 10 m/s). In general, only 1.2% of annual winds, 2.7% of winter winds and

0.26% of summer winds are strong and exceed 10 m/s.

• The direction of significant winds (wind speed larger than 6 m/s) is NNW with

1.64% occurrence. The dominant direction of strong winds (wind speed larger

than 10 m/s) able to generate wave storms and strong currents is SW with

0.30% occurrence.

• The strongest winds are in reasonable agreement with wave storm events in

deep water. The maximum wind speed 21.8 m/s was recorded during the winter

storm event on 12.12.2010. In that storm the wave significant height at the

Ashdod buoy location larger than 6m. The corresponding wind direction was

SSW.



B - 33

10.3.2.1 Currents:

The statistical analysis of currents in the, according to measurement stations

Asd1-Asd3 (most relevant stations) and CM1-CM3, in Ashdod area shows that:

• Most of the time (90%), the speed of near-surface current does not exceed 35

cm/s at Asd1, Asd2 and Asd3 stations, 25 cm/s at CM1 station and 15 cm/s at CM3

station; and the speed of the near-bottom current does not exceed 25 cm/s at

Asd1, Asd2 and Asd3 stations, 20 cm/s at CM1 station and 10 cm/s at CM3 station.

• The larger velocities were recorded close to the water surface. The largest near-

surface and near-bottom speeds recorded were: at Asd1, Asd2 and Asd3

stations (10 years of measurements) ~ 120 cm/s and 85.0 cm/s respectively; (b) at

Cm1 station for every short time of records (1 year of measurements only) ~ 61

cm/s and 60 cm/s, respectively; (c) at Cm3 station for every short time of records (1

year of measurements only) ~ 41 cm/s and 32 cm/s, respectively.

• The predominant direction of currents is from south to north along shore.



B - 34

10.3.2.2 Seawater Temperature:

The statistical analysis of seawater temperature in the Ashdod area shows that:

• Seawater temperature range from 12.5 ºC in winter to 32.8 ºC in summer. The

average temperatures in winter are 19.6 ºC, 26.2 ºC in summer and 23.4 ºC on

a yearly basis.

• Seawater temperatures are larger than 19.0 ºC for 50% of winter records, 27.5

ºC for 50% of summer records and 23.0 ºC for 50% of annual records.

• Only 10% of winter records show temperature lower than 17.0 ºC, only 10% of

summer records show temperatures lower than 20.0 ºC and only 10% of annual

records show temperature lower than 17.5 ºC.

• Only 10% of winter records show temperature larger than 24.0 ºC, only 10% of

summer records show temperatures larger than 30.5 ºC and only 10% of annual

records show temperature larger than 30.0 ºC.

10.3.2.3 Air Temperature:

Records at the "Negba" meteorological station (Nearest one to Ashdod) during

1981-2000 show that:

• The daily mean maximum and minimum air temperature measured by Israeli

meteorological services "IMS" are +31.1 ºC in August and +8 ºC in February.


B - 35

• The highest daily maximum and the lowest daily minimum air temperature are

+42.4 ºC in September and -0.7 ºC in February.

10.3.3 Wind Load to be considered for the design of Onshore above ground structures:

The calculation of wind loads on above ground structures in Israel is governed by

the provisions of the Israeli Standard SI 414 (latest edition at contract signing)

“Characteristic Loads in building: Wind Load”.

The calculation shall be accomplished using the basic design wind velocity,

defined below.

According to this Israeli Standard, the basic design wind velocity is defined as

the average velocity for ten (10) minutes, with an average return period of fifty

(50) years, at an altitude of ten (10) meters above ground level, and in a flat open

country terrain with only a few obstacles (Roughness Category II)".

The maximum upper gust velocity (three (3) seconds average) can be calculated

by multiplying the fundamental basic design wind velocity (ten (10) minute

average) by a factor of 1.50.

The fundamental basic design shall be taken from the velocity map which forms

an integral part of the standard.

For the site of the project, the fundamental basic design wind velocity indicated

by this Standard is 30 m/sec.

Roughness Category 0 shall be assumed at the project site.

Note:

For the full Hydrographic data of Ashdod region, refer to Supplement-16,

"Processing of Hydrographic Data for Ashdod Region.

10.3.4 Earthquake Loads to be considered for the design of above ground structures

(Onshore):

The seismic design of buildings and structures in Israel is governed by the

provisions of the Israeli Standard SI 413 “Design Provisions for the Earthquake


B - 36

Resistance of Structures” (Combined Edition 5 (2013) and Amendments 6

(2016), 7 (2017) and 8 (2018) are currently in force).

According to this Standard, the seismicity of the site is expressed by the

expected horizontal ground acceleration coefficient Z and corresponding mapped

horizontal spectral response acceleration parameters Ss and S1.

The expected horizontal ground acceleration coefficient Z expressed as:

Z = ah,max/g.

The expected ground acceleration is a forecast of the peak of the horizontal

ground acceleration due to an earthquake, ah,max, expressed in m/sec², for which

there is a given probability (10%, 5%, 2%) that a stronger acceleration will occur

at least once within a period of 50 years. The gravity acceleration g = 9.81

m/sec2.

For Plant site the following parameters shall be assumed.

For 10% probability (475 years return period):

Z = 0.06, Ss = 0.15, S1 = 0.04

For 2% probability (2475 years return period):

Z = 0.11, Ss = 0.28, S1 = 0.07

Site Class by soil profile type shall be determined by Geotechnical Consultant.

Site Class D is assumed.

Power Plant is included in Group A with importance factor I=1.4.

Site specific response spectrum shall be taken into consideration.

10.3.5 Exposure Classes for concrete structures

Exposure classes related to environmental conditions in accordance with Israeli

Standards SI 118 and SI 466 will be at least as follows:
