Honeywell safety system for INEOS plant in Norway
3 Jun 2010
Oslo – Honeywell is to improve operational safety at a major ethylene plant operated by Noretyl AS, part of INEOS. The scope of work includes the immediate installation of four Safety Manager systems and three redundant C300 controllers at the plant in Rafnes, Norway. The vendor will also provide local services and support and eventually will replace all the plant’s remaining, ageing safety systems.
The project includes integrating the plant’s existing Honeywell DCS with Safety Manager, which has a diagnostic coverage of 99.99% and can be used for simultaneously processing multiple Safety Integrity Functions (SIFs) that require up to Safety Integrity Level 3 (SIL3).
This approach, said Honeywell, will give Noretyl operators one common user interface across both systems, helping them more quickly see and understand critical situations. Maintenance costs should be reduced significantly as Noretyl uses a single supplier for both the DCS and safety systems. Additionally, the system is easier and more intuitive to operate.
The Rafnes plant manufactures some 550ktpa of ethylene and 80ktpa propylene every year. Noretyl is owned by INEOS, the world’s third largest chemicals company.
