Major Challenges Cut-over the entire system and integrate with PVC DBN
project in just 14 days
Management provided window of 14 days during ATA to make system up and running including new addition of PVC DBN Project
It was very challenging considering the fact similar task would take
not less than 21 days as per industry norms

Major Challenges Cut-over the entire system and integrate with PVC DBN project in just 14 days Hardware execution by Yokogawa and Software execution by Oxy-Vinyl, Process
Licensor
PVC DBN Project, Batch Process Software Enhancement and Lack of Pseudo-codes for MODCOMP programs were driving force to involve Process Licensor, Oxy-Vinyl for Application Software Development

Major Challenges Cut-over the entire system and integrate with PVC DBN project in just 14 days Hardware execution by Yokogawa and Software execution by Oxy-Vinyl, Process Licensor Lack of Pseudo code or Logic Narratives for MODCOMP Batch programs and HIMA Logic
For some reasons, Plant did not have these very vital documents to understand basis of application and subsequent approval of new application development

Unbelievable but true…
None of the wires in the plant, whether in field JB or Control room had Ferrules/Tags on themSince It was require to disconnect and re-connect more than 16,000 wires in control room it could create real chaos!!

Even though Plant documentation is updated regularly, about 18 years of Plant Operations and Hundreds of Plant Modifications calls for exact mapping of plant conditionsWe were not prepared to take even smallest of chance which could cost us a lot later
