Halliburton Pipeline Unit Wins Award

Halliburton's Energy Services Group announced that its Pipeline and Process Services division has been awarded the 2003 Subsea Pipeline Technology Award by the Pipeline Industries Guild for the development and successful application of its new Hal-AT™ Acoustic Telemetry System. The award, introduced by the Guild in 1993, highlights the significant contribution Halliburton has made to subsea pipeline technology around the world.

John Banyard, President of the Guild, presented the award to Halliburton at the Guild's Annual Dinner held at the Grosvenor House in London, March 11th. The Guild's annual dinner is widely recognized as the premier social event for all those concerned with pipelines worldwide. It regularly attracts more than 1,000 people and therefore provides an unrivalled networking opportunity as well as a knowledgeable and influential audience.

The Hal-AT System is a real-time, remote subsea system which allows for more accurate predictions of pig location. This is done by using the pressure monitoring function at the launch point, or the pig tracking/signaling function further along the pipeline. The system can also be of benefit during pre-commissioning/hydrotesting activities by allowing the support vessel to move off-station and continue its work elsewhere whilst still monitoring the pressure trend within the pipeline under test. It uses an acoustic transponder as the link between a subsea location and a vessel-based monitoring station The transponder can be deployed in water depths of up to 2,000 m.

The system has two main benefits. First, by accurately monitoring pipeline pressure during pigging runs, it removes the uncertainty factor relating to pig location and negates the industry-wide practice of pumping overfills for pipelines and flowlines in deepwater environments. This reduces the quantity of chemicals required during a project and reduces potential environmental impact. Second, it can reduce vessel time by eliminating 'best guess' estimates. These combined benefits can lead to an overall reduction in project costs for a client.

Halliburton began development of the first Hal-AT prototype in 1997 in response to the need to accurately determine the pressure within a pipeline during deepwater pigging operations and to ensure the success of pigging runs. Throughout its development the system has undergone numerous trials, and refinements to the technology have increased its ability to detect and monitor a wide range of parameters.

The most recent application of the system was in early 2002 during the pre-commissioning activities of two infield flowlines for a deepwater project in the Gulf of Mexico. The Hal-AT system generated proven real-time accurate pressure readings and analysis of pig progress.

Commenting on the award, Steve Arrington, Halliburton's Business Segment Manager for Pipeline and Process Services, said, "Hal-AT is truly enabling technology that provides a step-change in the pre-commissioning philosophy for deepwater pipelines. This technology has the potential to significantly reduce our clients' overall pre-commissioning costs for deepwater installations. Successful implementation of technology such as HAL-AT provides our clients with the flexibility to perform operations which were previously either problematic, or in some cases, virtually impossible to carry out using conventional monitoring and data collection systems."
