SAES-A-112 Meteorological and Seismic Design Data

Scope This standard defines the basic meteorological and seismic data to be used in the design of all Saudi Aramco facilities. These data are presented in tabular form in Appendix I. Commentary Notes: Saudi Aramco meteorological data generally are based on a minimum of 10 years of data. However, where weather records are available, data have been based on longer periods; where records are limited, data have been based on the maximum available time period. As pertinent reference material becomes available, meteorological data for Saudi Aramco installations will be revised and expanded.

This entire standard may be attached to and made a part of purchase orders.

Minimum Design Loads for Buildings and Other Structures

Definitions This section defines the meteorological and seismic data presented in Tables 1 & 2 and indicates some of the areas in which these data are commonly used. 4.1

Site elevation and station coordinates: although not considered meteorological or seismic data, are included in this standard for the convenience of the user. Elevation Above Mean Sea Level: Approximate elevations are listed for Saudi Aramco sites and referenced to Mean Sea Level (MSL). Commentary Note: These elevations are used by process, equipment, and utility engineers for calculation of atmospheric atmospheric pressure. Seasonal site specific atmospheric atmospheric pressure is also available from the Environmental Protection Department.

Station Coordinates: The approximate latitude and longitude of the plant site in the units of degrees and minutes. Commentary Note: This information can be used in HVAC design to determine the position of the sun at various times of the year.

4.2

Ambient Air & Soil Temperatures: Temperature readings obtained from the Saudi Aramco and MEPA local weather stations are as follows: Page 3 of 25



Average Annual Temperature: An average of the daily temperatures for the year averaged over a number of years. Average Daily Maximum Temperature: An average of the daily temperatures for the hottest month averaged over a number of years. Commentary Note: This value is used in the rating of transformers and electric motors.

Monthly Normal Maximum Temperature: The average of the maximum daily temperature recorded during the hottest month averaged over a number of years. Commentary Note: This value is used in the rating of transformers and electric motors.

Average Daily Soil Temperature: The average daily soil temperature for the hottest month, measured one meter below grade, averaged over a number of years. Commentary Note: This value is used for underground cable applications and buried pipelines.

Monthly Normal Maximum Soil Temperature: The average of the maximum daily soil temperature, measured one meter below grade, during the hottest month averaged over a number of years. Commentary Note: This value is used for underground cable applications and buried pipelines.

Lowest One Day Mean Temperature: This temperature is determined by finding the lowest value of the daily mean temperatures over the entire period of records. Commentary Note: An ambient temperature that may be required for the minimum design metal temperature for equipment that is significantly pressurized at ambient temperatures.

Highest One Day Mean Temperature: This temperature is determined by finding the highest value of the daily mean temperatures over the entire period of records.

Page 4 of 25



Commentary Note: An ambient temperature that may be required to determine the maximum metal temperatures used in the design of structures, piping systems and certain types of equipment.

Lowest Recorded Temperature: The lowest ambient air temperature that has been recorded at a particular site. Highest Recorded Temperature: The highest ambient air temperature that has been recorded at a particular site. Summer Design Dry Bulb Temperature: A dry bulb temperature that has been equaled or exceeded by 1%, 2.5% or 5% (30 hrs, 73 hrs, or 146 hrs) of the total hours during the months of June through September. Wet Bulb Temperature: The lowest temperature that can be obtained by evaporating water into the air. Mean Coincident Wet Bulb Temperature: The mean of all wet bulb temperatures occurring at the specific Summer Design Dry Bulb Temperature. Summer Design Wet Bulb Temperature: A wet bulb temperature that has been equaled or exceeded by either 1% or 2.5% (30 hrs or 73 hrs) of the total hours during the months of June through September. Mean Coincident Dry Bulb Temperature: The mean of all dry bulb temperatures occurring at the specific summer design wet bulb temperature. Mean Daily Range: The difference between the average daily maximum and average daily minimum temperatures during the month of August. Winter Design Dry Bulb Temperature: A temperature that has been equaled or exceeded by 99% of the total hours during the months of December, January and February.

4.3

Wind: Wind data compiled from local weather stations are reported as follows: Basic Wind Speed: The wind speeds are derived from local weather station data. Both 3-second gust and Fastest Mile Wind Speeds are expressed in both SI and customary units at 10 m above ground for 50-year mean recurrence intervals. Commentary Note: This data is used for the design of structures, buildings, pressure vessels, piping, storage tanks, air-cooled heat exchangers, cooling towers, stacks, and similar equipment. Page 5 of 25



Exposure Category: An exposure category reflects the characteristic of ground surface irregularities at a particular site. Commentary Note: This category is used to account for large variations in ground surface roughness that arises from natural topography and vegetation as well as from constructed features. This factor is used in calculating calculating wind pressures using either the IBC or ASCE 7.

Prevailing Direction: The direction (N, NNE, NE, ENE, E, etc.) from which the wind blows the greatest percentage of the time. Commentary Note: Since 16 points of direction (N, NNE, NE, ENE, E, etc.) are used to discuss wind direction, the directions given in Table 1 could represent less than 10% of the total time the wind is blowing. blowing. Where wind direction considerations considerations are critical, a wind rose diagram may be available from the Environmental Protection Department.

4.4

Earthquake Data Short Period Acceleration (SS): The mapped maximum considered earthquake spectral response acceleration at a short period. One-Second Period Acceleration (S1): The mapped maximum considered earthquake spectral response acceleration at a period of 1-sec. Commentary Note: S S SAER-6089. They are to be S and S 1 values have been determined based on SAER-6089. used as per procedures in ASCE 7-02 and IBC 2003 to calculate the design spectral response acceleration parameters.

Site Class: A classification assigned to a site based on the types of soils present and their engineering properties as per IBC or ASCE 7 Site Classification Tables 1615.1.1 or 9.4.1.2 respectively.

4.5

Precipitation Commentary Note: The amount of precipitation (rainfall) is a factor used in storage tank design, drainage design, waste-water discharge discharge quality control, and similar similar items. It should be realized that the desert climate and length of record make recorded values highly variable (for example, Dhahran has 60 years of data while Tanajib has 12 years).

Rainfall, Average Annual: This is the annual average rainfall based on as many years of data as available. Rainfall Maximum in 24 Hours: This is the maximum precipitation recorded in 24 hours. Rainfall Intensity Coefficients: These coefficients are provided for return periods of 5, 10, 25 and 50 years. The coefficients are used in the Steel Formula [I = K/(t+b)] to calculate the average maximum precipitation rates for storm durations up to two hours. Where:

I

=

Rainfall Intensity in mm/hr (in/hr),

t

=

time of concentration in minutes, and

K & b are non-dimensional coefficients. Isokeraunic Levels: A rough measure of lightning frequency. Commentary Note: These values are used in the design of grounding and lightning protection systems.

4.6

Ambient Air Quality Commentary Note: Air-borne dust concentrations and contaminant levels are used in mechanical equipment design, when sizing air filters and as a measure of potential dust ingress in bearing housings, lube oil systems, etc.

Dust Concentration: Usual airborne dust concentration is 1 mg/m³. During sandstorms, dust concentrations may reach 500 mg/m³. mg/m³. Particle sizes are as follows:

95% of all particles are less than 20 micrometers 50% of all particles are less than 1.5 micrometers Elements present in dust include compounds of calcium, silicon, magnesium, aluminum, potassium, chlorides and sodium. When wetted (high humidity conditions) these compounds function as electrolytes and can result in severe corrosion. Other pollutants present in the atmosphere under the most extreme conditions are: H2S Hydrocarbon SO2
