Invensys wins first ever contract from Borealis

14-Mar-06

Invensys Systems Austria has won its first ever contract from Borealis, one of the world's leading manufacturers of polyethylene and polypropylene. Under the terms of the contract, Invensys is to supply its Triconex-brand TMR (triple modular redundant) TRICON controllers for safety instrumented system (SIS) applications on the new PE4, a Euro 200 million, 350,000 tpa linear low density polyethylene (LLDPE) plant being built at Schwechat in Austria. LLDPE is used to manufacture plastic film products, such as packaging materials. The TRICON is based on a triple modular redundant (TMR) architecture that uses three isolated, parallel control systems and extensive diagnostics integrated into one system. This uses two-out-of-three voting to provide high integrity, error free, uninterrupted operation with no single point of failure.
