Invensys Safety Instrumented Systems to be Implemented for Nine PEMEX Offshore Platforms


TMR systems to be used for emergency shutdown and fire and gas safety on platform assets in phased Ku Maloob Zaap oil fields expansion

FOXBORO, MASSACHUSETTS, USA - June 14, 2006 - Invensys Process Systems will supply 11 Triconex (www.triconex.com) safety instrumented systems (SIS) as part of an operations, safety and security upgrade in major offshore projects for Petróleos Mexicanos (PEMEX). At the Ku Maloob Zaap oilfields off the coast of Campeche State, Mexico, PEMEX Exploration and Production Northeast Marine Region (PEP) is undertaking a significant upgrade and expansion of its drilling and production infrastructure. Triconex emergency shutdown systems and fire and gas safety systems will be installed on nine platforms.

The Ku Maloob Zaap expansion is a major initiative in Mexico's national oil production strategy. Ultimately, more than 100 new wells will be added to PEMEX's asset base, producing approximately 800,000 barrels per day of heavy Maya crude to meet future domestic demands for oil and gas.

The 11 Tricon TMR (triple-modular-redundant) control systems will be deployed at critical sites in five different complexes throughout the extensive Ku Maloop Zaap offshore infrastructure. The systems will provide emergency platform shutdown functions to protect six production platforms and one linking platform in the network. Triconex fire and gas systems will also protect three production platforms and one crew platform that houses about 70 workers.

The selection of the Tricon systems will provide PEMEX with the highest levels of availability, safety, and reliability. The systems monitor a variety of parameters against preset safety limits. These parameters include platform equipment status, detection for smoke, hydrogen, toxic gases and combustion gases, control of fire suppression equipment, alarm management and manual shutdown controls.

The Invensys implementation also includes a range of professional services from Invensys Process Systems Mexico, including engineering, programming, local assembly, acceptance testing, training and commissioning.

The new contract builds on extensive Invensys experience with PEMEX. Invensys systems for distributed plant control, safety and SCADA applications have been used at PEMEX onshore and offshore pipelines, platforms and refineries for more than 20 years.

The Tricon is an industry-certified state-of -the-art fault tolerant controller based on TMR architecture for safety and critical control applications. TMR architecture employs three isolated, parallel control systems and extensive diagnostics integrated into one system. The system uses two-out-of-three voting to provide high integrity, error-free, uninterrupted process operation with no single point of failure. The Tricon controller's redundant control functions and diagnostics are embedded and transparent, and the system behaves as a single control device to the engineer or operator.
