| Name | BOP_Ram |

| Entity Type | Table |
| Description | The closing and sealing component on a ram type blowout preventer. One of three types--blind, pipe, or shear--may be installed in several preventers mounted in a stack on top of the well bore. Blind rams, when closed, form a seal on a hole that has no drill pipe in it; pipe rams, when closed, seal around the pipe; shear rams cut through drill pipe and then form a seal. |

|---|---|---|---|---|---|
| BOP_Id | Blowout_Preventer |
|
The identifier of the Blowout Preventer of which the BOP Ram is a part. | Yes |
NUMBER(38) |
| 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 |
VARCHAR2(128) |
| Id | ID | No_Unit |
Unique identifier for this entity. | Yes |
NUMBER(38) |
| Insert_Date | DATE | NA |
Date the entity was created in the repository | No |
DATE |
| Insert_User | STRING64 | NA |
The name of the user responsible for the creation of this entity in the repository. | No |
VARCHAR2(64) |
| Max_Sealing_Pipe_Diameter | double | Cylinder_Diameter mm |
A measurement to indicate the maximum size of the pipe that the ram can seal. Note that variable rams can seal over a range of pipe sizes. For standard pipe rams this will be the same as the Min_Sealing_Pipe_Diameter. | No |

| Min_Sealing_Pipe_Diameter | double | Cylinder_Diameter mm |
A measurement to indicate the minimum size of the pipe that the ram can seal. Note that variable rams can seal over a range of pipe sizes. | No |
NUMBER |

The name of application role that created the entity, for data created programmatically. | No |
VARCHAR2(64) |
| Ram_Type | CODE | NA |
A classification to indicate the type of Ram installed in the BOP. Ex. Standard Pipe Ram, Variable Pipe Ram, Shear Ram, Blind Ram. | No |
