Customer case:

Successful I/O migration at Borealis Porvoo

Jan 24, 2019

The Borealis Polymers Porvoo plant in Finland, a fully integrated petrochemical complex, has been controlled with automation from Valmet since 1993. As a result, several generations of automation have been periodically extended and upgraded until ultimately replaced as components reach end of life and new technological solutions are introduced. As part of a modernization project to the Olefin Cracker in 2017, Valmet undertook the major task of replacing over 3000 centralized input/output (CIO) cards in 31 I/O cabinets.

Valmet performed very well during the whole project with very skilled personnel. After the turnaround the startup went well and after one year we have only had to replace 3 cards, so-called infantile failures in the first few months, which has been very good. Our maintenance personnel are also really happy now with the new I/O supporting HART and FDT/DTM data transfer from field instruments and valve positioners which makes their job much easier.
