Neste announced Tuesday that its Porvoo refinery is back in production after a scheduled maintenance turnaround.
“The refinery start-up proceeded as planned, and normal utilization should be reached within a few days,” Finland-based Neste said.
The turnaround began in April and was the largest in the history of the refinery.
Neste said that the nearly three month long turnaround will help ensure the refinery’s good performance and safety for the next four to six years.
As part of the major turnaround, conducted once every five years, the entire refinery was shut down, equipment was cleaned and inspected, pressure vessels were inspected, new investments were connected to the processes,and required preparations were made for connecting known investments.
During the turnaround, about 4,500 people from 30 countries worked at the Poorvoo refinery.
Neste said that “slight delays in investment work in some units” means the turnaround is expected to have a negative impact of about $140 million on the oil products segment’s comparable operating profit.
The firm added that the negative impact will mainly be felt during the second quarter.
The impact had previously been expected to be about $112 million.
Neste’s guidance remains unchanged, with full year 2015 comparable operating profit estimated “to remain robust, and to be higher than that reached in 2014.”
