Default		Type
API_Product_Spec_Level CODE NA
 Product Specification Level (PSL) as defined by API. The PSL indicates the service conditions for which the wellhead may be used. API has defined four PSLs for wellhead - PSL1, PSL2, PSL3, and PSL4. The four PSL designations define different levels of technical requirements. No
 VARCHAR2(64)
API_Temperature_Class CODE NA
 An API classification to indicate the temperature range that the equipment is designed to operate. Examples of API temperature class are K, L, P, R, S, T, U, and V. No
 VARCHAR2(64)
Address_Id Address
The address of the Tracked Facility No
 NUMBER(38)
Bottom_Side_API_Ring_Number CODE NA

 Type of connection on the bottom side of the equipment or component. No
 VARCHAR2(64)
Bottom_Side_Nominal_Size double Cylinder_Diameter
mm		 A measurement to indicate the nominal size of the equipment or component on it s bottom side. It is typically expressed as a diameter measurement. No
 NUMBER

kPa		 A measurement of the rated working pressure on the bottom side of the equipment or component. No
 NUMBER
Catalog_Cost double No_Unit

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)
Facility_Equipment_Flag CODE NA
 A flag to denote whether a given facility should be treated as a facility (F), a piece of equipment (E) or both (B). A facility labeled as F represents a role (e.g. ESP) played by physical piece(s) of equipment and would not have attributes like serial number, manufacturer etc. It can be related to the physical pieces(s) of equipment using Facility_Composition. The individual physical pieces can be replaced if they need to be, without changing the facility. A Facility labeled as E represents a physical piece of equipment (e.g. Drill Pipe) which is normally used in the context of an activity and would not be permanently installed. A facility labeled as B represents both a physical piece of equipment as well as the role played by it. If this kind of Facility is connected in the network and stops working and needs to be replaced, then all connections to this Facility are expired and new connections are made to the replacement facility. No
 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
