Type
Compressor_Id Compressor
The identifier of the compressor described by the set of operating properties. Yes
NUMBER(38)
Differential_Pressure double Pressure
kPa
The fluid pressure differential across the compressor. No
NUMBER
Discharge_Pressure double Pressure
kPa
The pressure of the fluid at the discharge point of the compressor. No
NUMBER
Efficiency double Percent
%
The ratio of the useful energy delivered by a dynamic system to the energy supplied to it. No
NUMBER
End_Date DATE NA
End date and time of the validity of these properties No
DATE
Existence_Kind REF_EXISTENCE_KIND NA
A reference value that describes the state of existence in the lifecycle of the entity, for example, Planned, Predicted, Required, Simulated, and Actual. Yes
Actual
VARCHAR2(64)
GUID STRING128 NA
Globally Unique IDentifier for an instance of a class. USAGE NOTES: There are two cases: 1) GUID is not populated or used; and 2) it is populated with a value that is globally unique. If the GUID is populated there are two means of doing so for a given project: 2a) Seabed automatically generates and populates the GUID when an instance is created (valid only on Oracle based systems); and 2b) the GUID is generated and populated by an application (other than Seabed) on instance creation. Whether Seabed automatically generates GUIDs for a project is determined by the Auto_GUID flag in SDS_Account. Note that techniques 2a and 2b can coexist in the same project. When GUIDs are automatically generated an application can override the automatically generated GUID with its own GUID by simply supplying the GUID value. Applications that generate their own GUIDs and populate the GUID column will function correctly on projects which have automatic GUID generation turned on. No
