Plants

Information on industrial plants is stored in the system as plant records. Data on plants includes the plant name, industrial activity, location information, operator information and site conditions such as environmental factors or soil properties.

The data fields of the plant records are listed in Table 1.

Table 1. Plant data fields

When entering plant information, the name of the plant can be stated in multiple languages. The industrial activity should be selected from the list of available activities (NACE codes) in the database. The status of the plant, indicating whether the plant is operational, shutdown or will be available in the future, can be mentioned. Descriptive location information includes country, province, city and address. The exact location of the plant can be marked on the map by drawing the polygon boundary, or its central geographic coordinate can be indicated as latitude and longitude. The coordinate field is linked to the map and updated automatically according to the drawn boundary. See "Mapping" section for more details on the mapping features of the system. The name of the operator of the plant can be in-dicated and contact information can be entered such as mailing address, phone, fax, and web site ad-dress (Figure 1).

Site-specific properties of the plant can be indicated by using the generic property definition mechanism of the system. Plant properties are divided into two groups: The first group is in the plant context and related to the physical characteristics of the plant itself, such as year of construction or year of last major upgrade. The second group is in the site context and related to the site and its surroundings. Soil characteristics (e.g. soil class) or environmental properties (e.g. topography) can be given as example properties in this group. Similar to other record types, plant properties support fuzzy values and available property estimators can estimate missing properties wherever possible.

Plant properties in the site context are considered valid also for the plant units located at the plant. RAPID-N performs risk assessment calculations at plant unit level and reports the results for plants. While performing the calculations, the system tries to use more accurate and detailed data wherever possible. Since plant units are located within a plant and site conditions do not vary significantly within the plant boundaries, plant properties are used to approximate site-specific properties of plant units.

The records related to the plant can be accessed from the plant information page. Units of the industrial plant available in the database are listed. Natechs that occurred at the facil-ity and risk assessments that cover the plant are displayed, as well.
