Notes
- The arrows show direction, not volume. The direction is the source's from → to for each pipeline. The source has no flow per pipeline. Pipelines without from and to in the source are shown without direction.
- BOEM's pipelines end at an installation or at the boundary to state waters. The route onward to shore, the pipeline owners and the capacity are not in BOEM's data. Only active pipelines of at least 10 inches for oil, gas and condensate are included. The pipeline operator is the operator BOEM gives for the segment in the pipeline file (FACIL_OPERATOR, at the latest inspection). A pipeline is linked to an installation when BOEM's platform id in the pipeline file (platform name, area and block, for example “A MC 807”) equals the platform name without the nickname in brackets, area and block in the platform file (“MC 807 A (Mars)”), and the match is unique.
