10 Installation Site Assessment
Before installing equipment at a site, the characteristics of the site should be
considered to determine whether they will adversely affect the reliability of the
equipment. The following section discusses some of the site factors to consider prior
to deploying equipment.
10.1 Geographical Location
Different geographical locations carry different risk factors. For example, coastal
installations with prevailing winds from the sea may be affected by Airborne Sea Salt
Particles (ASSP), which can be carried many kilometers inland. As well, installations
near ancient seabeds that have very high levels of salt in the soil may be affected by
ASSP during windy drought conditions. Mountainous regions near coasts cause
unique fog conditions. High humidity environments often cross dew point thresholds
at night.
Consider whether the installation site is in an area that has the potential to
experience any of the following seasonal influences: hurricanes, cyclones, tidal or
river flooding, recent volcanic activity, or forest fires.
Examine the local surrounding environment of the installation site for proximity to
possible sources of contaminants that may cause or accelerate corrosion, especially
in the presence of high humidity.
Possible sources of contaminants include: landfills, fertilizer manufacturing, farming,
sewage, geothermal activity, swamps or marshes, oceans, ancient seabeds, power
generation, automotive and diesel combustion, fossil fuel processing, cement plants,
construction sites, steel blast furnaces, steel electric furnaces, coke plants, pulp
manufacturing, chlorine plants, rubber manufacturing, paint manufacturing,
aluminum manufacturing, ore smelting, tobacco smoke, and battery manufacturing.
If there is any uncertainty surrounding the concentration of various contaminants at
the installation site, then Corrosion Classification Coupons may be used to classify
the severity of the environment according to the standard ISA 71.04
