Booming U.S. NGL Exports Idled With Houston Channel Shut
The closing of the Houston Ship Channel after a fuel spill is idling vessels that carried a record amount of U.S. natural gas liquids exports last year, raising questions about the need for geographic diversity in the burgeoning market.
Most U.S. capacity to export NGLs is on the channel, said Peter Fasullo, a principal at Houston-based energy consultant EnVantage Inc. The U.S. averaged 475,000 barrels a day of exports in 2013, up from 164,000 in 2010, according to Energy Information Administration data. Two companies, Enterprise Products Partners LP (EPD) and Targa Resources Partners LP (NGLS), have channel operations that combine to represent 380,000 barrels a day of export capacity, Fasullo said.
“That’s all going to go offline,” Fasullo said. “Ships can’t get into the terminals to get loaded, and those that are loaded can’t get out.”
Authorities hoped to open part of the 52-mile (83-kilometer) channel today, Greg Beuerman, a spokesman for the U.S. Coast, said in a telephone interview. The channel was shut March 22 when a vessel and barge collided close to where the waterway meets the Gulf of Mexico, spilling about 4,000 barrels of bunker oil.
The channel was closed from just north of Texas City down to its entrance, at Bolivar. To reopen it, the Coast Guard needs an uncontaminated lane for ship traffic and to be sure the traffic won’t impede cleanup, Captain Brian Penoyer said.
Enterprise operates a 14,000-barrel-an-hour tanker terminal and a 5,000-barrel-an-hour barge facility on the channel. Capabilities at those facilities have been “limited somewhat,” Houston-based spokesman Rick Rainey said by e-mail.
Targa can export 115,000 to 130,000 barrels a day from its terminal in Galena Park. Jennifer Kneale, a Houston-based spokeswoman for the company, declined to comment on operations.
The ship channel is the closest waterway to Mont Belvieu, Texas, home to the largest NGL storage capacity in the world. Terminals on the channel have been the “workhorse” for NGL exports so far, Fasullo said. Propane swaps traded at $1.059 a gallon yesterday at Mont Belvieu, according to New York Mercantile Exchange data. They declined 17 percent this year.
Companies are planning to spend $35 billion on new projects and expansions along the ship channel, according to a 2012 Greater Houston Port Bureau survey. The weekend spill is the type of incident that can raise questions about how much more traffic the channel can take, Fasullo said.
“The industry has to think about how much infrastructure the channel can really handle,” he said. “Because we’re putting a whole lot of traffic on one waterway.”
Companies including Phillips 66 (PSX) and Occidental Petroleum Corp. are planning NGL export terminals at other Texas ports. Occidental plans to use most of the space on a 110,000-barrel-a-day NGL pipeline to Corpus Christi from Mont Belvieu for an export terminal at a former naval base in Ingleside, Texas.
Phillips 66 is investing in an NGL export terminal in Freeport, Texas, about 30 miles southwest of where the channel opens to the Gulf of Mexico. The spill illustrates why the U.S. NGL industry needs to spread export capacity to other areas, Jim Webster, Phillips 66’s general manager of midstream, said in an interview in Houston.
“It’s like your personal portfolio,” Webster said yesterday after speaking at the IHS International LPG Summit. “You want to diversify your risk, whether that’s in bonds and stocks or whether that’s in where fractionation capacity is and what waterways are used.”
