Enbridge to Build Crude Oil Pipeline in US GoM

Enbridge Inc., announced that it will build, own and operate a crude oil pipeline in the Gulf of Mexico to connect the proposed Heidelberg development, operated by Anadarko Petroleum Corporation, to an existing third-party pipeline system.

The lateral pipeline is expected to be operational by 2016. Construction of the pipeline is subject to finalization of definitive agreements and sanction of the development by Anadarko and its project co-owners.

The Heidelberg lateral will originate in Green Canyon Block 860, approximately 200 miles southwest of New Orleans and in 5300 feet of water. The pipeline will be 20 inches in diameter and approximately 34 miles in length.

“We are pleased to be working with Anadarko and the Heidelberg producers,” said Leon Zupan, President, Gas Pipelines. “The Heidelberg lateral pipeline is an attractive investment opportunity for Enbridge. It also furthers our objective of diversifying our offshore business to include facilities that support the substantial crude oil discoveries in the deepwater of the US Gulf Coast.”

Enbridge’s offshore pipelines transport approximately 40 per cent of the natural gas produced in the deepwater Gulf of Mexico. The company’s offshore assets include interests in 13 natural gas gathering and transmission pipelines and one crude oil pipeline in five major pipeline corridors off the coasts of Louisiana and Mississippi.

TDW Completes Subsea Pipeline Pressure Isolation in the Gulf of Mexico

TDW Offshore Services (TDW), a leading supplier of pipeline services and equipment, has successfully completed a subsea pipeline pressure isolation operation in the Gulf of Mexico. Carried out at a depth of 370 ft (113 m) against 870 psig, this isolation enabled the safe and effective tie-in of a piggable wye to the Mississippi Canyon Gas Pipeline, a 30-inch natural gas line running between the West Delta 143 platform – a hub facility for deepwater oil and gas production – and the Venice Gas Plant in Louisiana.

The isolation project utilized two remote-controlled 30-inch SmartPlug® dual module pressure isolation tools to isolate 45 miles of pipeline.

“The SmartPlug® isolation tool is certified to ‘Safety Class High’ in accordance with OS-F101 for Submarine Pipeline Systems and is uniquely suited for use in connection with diving operations,” says Bjørn-Olav Gilje, project manager for TDW.

Each tool was composed of two plug modules and two pigging modules. One of the tools provided double block isolation on the high pressure side of the tie-in location. The first module on the second tool provided a hydraulic locked barrier of the high pressure side for the divers installing the wye. The second module on the second tool was used to perform a leak test to verify integrity of the new wye after installation.

Following launch, TDW technicians aboard dive support vessel Norman Commander used the remotely-operated SmartTrack™ tracking and pressure monitoring system to continuously monitor the locations of the SmartPlug® tools as they traveled to their subsea set destinations. The SmartTrack™ system uses two-way, through-wall, electromagnetic communication between a transponder and a receiver to track tool progress. Once the tools were set, the isolation period was approximately two and a half weeks.

“TDW worked with the client and their contractors over several months to ensure that associated risks were evaluated and mitigated,” Gilje adds. “This thorough up-front planning resulted in a successful tie-in operation for our client. Working together achieved a result that we are proud to have been part of.”

EIA: U.S. Gas Pipeline Companies Added 2,400 Miles of New Pipe in 2011

The U.S. Energy Information Administration said in a report that it estimates that U.S. natural gas pipeline companies added about 2,400 miles of new pipe to the grid as part of over 25 projects in 2011.

New pipeline projects entered service in parts of the U.S. natural gas grid that can be congested: California, Florida, and parts of the Northeast. Only a portion of this capacity serves incremental natural gas use; most of these projects facilitate better linkages across the existing natural gas grid, the EIA said.

By convention, the industry expresses annual capacity additions as the sum of the capacities of all the projects completed in that year. By this measure, the industry added 13.7 billion cubic feet per day (Bcf/d) of new capacity to the grid in 2011. The six largest projects put into service in 2011 added 1,553 miles and about 8.2 Bcf/d of new capacity to the system. Much of this new capacity is for transporting natural gas between states rather than within states. Golden Pass, Ruby Pipeline, FGT Phase VIII, Pascagoula Expansion, and Bison Pipeline projects added 6.1 Bcf/d, or about 80%, of new state-to-state capacity.

The EIA said that natural gas pipeline capacity additions in 2011 were well above the 10 Bcf/d levels typical from 2001-2006, roughly the same as additions in 2007 and 2010, but significantly below additions in 2008 and 2009. Capacity added in 2008 and 2009 reflected a mix of intrastate and interstate natural gas pipeline expansions, related mostly to shale production, liquefied natural gas (LNG) terminals, and storage facilities.
