Sea Robin Pipeline Delivers Offshore Volumes To Gulf, Midwest

Sea Robin Pipeline is one of the largest pipeline systems in the offshore Gulf of Mexico in terms of capacity and market reach. The system, owned by Southern Union Co. and operated by Panhandle Energy, is 440 miles in length with a capacity of 1 billion cubic feet per day (Bcf/d) of natural gas and has access to Gulf Coast and Midwest markets.

The pipeline is connected to systems owned by Columbia Gulf, Southern Natural, LRC, Sabine, Koch Gateway and Jefferson Island Storage. In addition, Southern Natural was the former owner of Sea Robin before selling the system in 1999 when it merged with El Paso Corp. Sea Robin Pipeline is also interconnected with the 1.7 Bcf/d Trunkline system that runs from the Gulf Coast to the Great Lakes.

According to Hart Energy Mapping & Data Services, the system’s top transport customers are Energy Resource Technology GOM Inc. at 35,000 dekatherms per day (Dth/d); Hess Corp. at 26,000 Dth/d; Deep Gulf Energy II LLC at 10,000 Dth/d; and Deep Gulf Energy LP at 5,000 Dth/d.

The system’s annual throughput has been consistent for the last few years with a peak of 396,000 Dth/d in 2007 and a low of 314,000 Dth/d. Sea Robin’s top receipt point was Chevron Midstream’s Fort Henry Receipt followed by Garden Banks Pipeline’s SMI 128S. Its top delivery point was Sea Robin to Bridgeline followed by Columbia Gulf Transmission.
