Pipeline Data for the Gulf of Mexico
NOTE: The segments with Nos. in the 500XXX range are located in State waters and we do not have some of the information including pipeline length. As for the other segments with regular MMS segment No. in the 10XXX range, for the most part, we assigned a SN when it was determined that an existing pipeline did not have one. This is a very old field and information is not available. Alex Alvarado, MMS Chief Pipeline Section.

| Destination Area/Block | The Area Code and designated OCS Block Number where the pipeline segment terminates. |
| Destination Lease No. | The number used to identify the mineral lease where a pipeline segment terminates. |
| Segment Number | The number assigned by MMS to each pipeline segment for purpose of internal identification. |
| ROW Number | A Right-of-Way identifier assigned to a pipeline approved under Title 30 CFR 250.250. |
| Status Codes | An indicator of the current status of the pipeline. Click for list of status code descriptions |
| Operator | The abbreviated name of the the operator of a facility at the time of inspection |
| Segment Length | The length of the Federal portion of the pipeline segment |
| Federal/ State Length | The length of the Federal and State portion of the pipeline. |
| Size | An indicator of the outside diameter of the pipeline. Click for list of size descriptions |
| Product | An indicator of the product being transported through a pipeline. Click for list of product descriptions |
| Direction of Flow | An indicator of the direction of flow of the pipeline segment. B=Bi-directional; D=Departing Platform; I=Incoming to Platform. |
| Bi-Directional | An indicator of whether the product in the pipeline can be passed in either direction. (Y/N) |
| Min Water Depth | The least vertical distance from mean sea level to the sea floor\ at the shallow part of the pipeline. |
| Max Water Depth | The greatest vertical distance from mean sea level to the sea floor. |
| Highest Operating Pressure Allowable | The highest operating pressure allowable at any point in a system during normal flow or static conditions. |
| Highest Operating Pressure Allowable in Receiving Pipeline | The highest operating pressure allowable in the receiving pipeline during normal flow or static conditions. |
| Buried at time of Installation | An indicator of whether a pipeline was buried at the time of installation. Y=Yes; N=No; S=Self; W=Waiver. |
| Type of Cathodic Protection | An indicator of the type of cathodic protection installed on the pipeline. |
| Cathodic Life | The length of time the pipeline cathodic protection is expected to be effective. |
| Leak Detection System | An indicator of whether a pipeline has a leak detection system installed and operational. (Y/N) |
| MMS' Commingling System | An indicator of the MMS' commingling system the pipeline is part of. |
| Boarding Pipeline Flow Safety Valve | An indicator of whether a boarding pipeline has a flow safety valve (FSV) installed and operational. (Y/N) |
| Boarding Pipeline Shut Down Valve | An indicator of whether a boarding pipeline has a shut down valve (SDV) installed and operational. Y=Yes; N=No; H=Holds; L=Leaks. |
| Proposed Construction Dt | The day, month, and year the operator has proposed to construct the pipeline segment. |
| Construction Date | The day, month, and year the pipeline was built. |

| Application Approval Dt | The day, month, and year the application was approved by MMS to authorize the installation of the platform. |
| Initial Hydrostatic Test Dt | The day, month, and year the first hydrostatic (HS) test is performed. Hydrostatic testing involves filling a pipeline with water under pressure to test the pipeline tensile strength or its ability to hold a certain pressure. |
| Anode Install Date | The day, month, and year the anode was installed or reinstalled on the pipeline system. |
| Approval | An indicator of whether the pipeline segment was approved under lease terms or right-of-way. L=Lease; R=ROW; S=State; U=MMS. |
| Pipeline Authority | The indicator of the authority under which the pipeline operates. I=Dept. of Interior; T=Dept. of Transportation. |
| Abandonment Approval Dt | The day, month, and year the application was approved by MMS to authorize the removal of the pipeline. |
| Abandonment Completion Dt | The day, month, and year the abandonment of the pipeline was completed by the operator. |
| Abandonment Method | The method used to abandon the pipeline segment. |
