This article is part of the Global Fossil Infrastructure Tracker, a project of Global Energy Monitor.

High Island Offshore Gas Pipeline System is an operating natural gas pipeline.[1]


The pipeline runs from gas fields located in the Galveston, Garden Banks, West Cameron and East Breaks areas of the Gulf of Mexico to a junction platform in West Cameron Block 167.[2]

The High Island Offshore Gas Pipeline System (HIOS) is owned and operated by Genesis Energy.[3] In November 2015 Genesis announced that it had sought permission from FERC to repurpose HIOS to send onshore gas to the proposed Delfin LNG deep water export terminal, while sending gas that had been flowing through HIOS through Genesis's Stingray Pipeline.[4] In September 2017 FERC approved this request on the grounds that HIOS’s gathering facilities have "the capacity to deliver its currently transported volumes of gas to Stingray Pipeline, and that Stingray Pipeline’s pressure will permit it to accept and transport the gas without causing operational problems."[5]


In June 2015 the Center for Biological Diversity submitted a Motion To Intervene with FERC against the Delfin FLNG facility that would be supplied by HIOS. The motion states: "The Center, on behalf of its members, strongly believes that the Project’s construction and operation, including exporting U.S. natural gas abroad, is not in the “public interest” because it will: (1) increase natural gas drilling in the United States, including the use of dangerous, controversial, and inadequately-regulated onshore and offshore hydraulic fracturing or “fracking” methods that contaminate water, degrade habitat, pollute the air, and require huge quantities of water; (2) harm wildlife and habitat and diminish air and water quality; (3) increase global warming due to emissions from wells, the energy intensive process of liquefying natural gas, and the ultimate use of the product; and (4) cause an increase in domestic gas prices for American homeowners. C.f. 18 C.F.R. § 153.7(c). Our members will be directly affected by the construction and operation of the Project."[6]
