Invensys to implement SCADA system for major expansion at GASCO Habshan gas plant in U.A.E.

FOXBORO, Mass. -- New digital monitoring and control, HMI solutions, and services to support expansion in Onshore Gas Development Phase III (OGD-III) project

Invensys Process Systems has been selected to provide advanced SCADA (Supervisory Control and Data Acquisition) systems for Abu Dhabi Gas Industries Ltd. (GASCO), who is managing the Habshan gas plant expansion project, OGD-III, on behalf of Abu Dhabi National Oil Company (ADNOC).

Located in the Emirate of Abu Dhabi, United Arab Emirates (U.A.E.), the Habshan complex is one of the largest gas processing plants in the world. The expansion is designed to process an additional 1,306 MMSCFD of condensate-rich gas at the Habshan complex.

The new systems will be used to monitor and control all gas wells and remote manifold stations associated with the Habshan complex. This includes replacement and expansion of existing SCADA systems with the latest Foxboro SCADA (www.foxboro.com) technology.

As part of the SCADA contract awarded by Eastern Bechtel Co. Ltd, the EPC contractor appointed by GASCO for the project, Invensys will provide professional services for project management, engineering, design, development, integration, testing, and on-site support, as well as training services for engineering and operating personnel.

The new SCADA project is designed to meet GASCO's main goals of maximizing the reliability and availability of gas well production and the inherent requirement for frequent cyclic polling of all critical production data. Overall project completion is scheduled for April 2008.

The Invensys SCADA architecture will employ a Wonderware (www.wonderware.com) kernel specifically configured for oil and gas applications and utilizing the award winning InTouch software as the foundation for the human machine interface (HMI). Field data and controls will be managed by remote sub-systems based on systems from the Foxboro RTU (Remote Terminal Unit) family. The RTUs will be located at more than 180 sites for existing and new gas production wells, remote manifold stations (RMS) and gas re-injection wells associated with the complex.

Approximately 10,000 I/O points throughout the Habshan complex will be controlled or monitored by the new SCADA system, including 8,000 relating to the production and injection wells and remote manifolds, with the balance relating to the well services emergency shutdown systems and DCS systems.
