Neste Oil´s Porvoo refinery's major maintenance turnaround began today

Neste Oil carries out a planned maintenance turnaround at its Porvoo refinery. The actual maintenance work started today and will continue around four weeks. Following this, the refinery unit start-ups will take another week.

Regular maintenance turnarounds every four to six years play an important part in keeping operations at Neste Oil's refineries safe and running at peak efficiency. Statutory pressure vessel inspections and maintenance also call for shutdowns at regular intervals.

The turnaround is estimated to involve close to a million man-hours of work and will employ some 2,500 people from outside contractors on site. During the major turnaround Neste Oil will sell products from its storages.

The previous major maintenance turnaround at Porvoo took place in 2005. Next major turnaround in another Neste Oil refinery in Finland, in Naantali, is scheduled for 2012.

Media visit to Porvoo

Neste Oil will arrange a media visit (in Finnish) to Porvoo on 14 April 2010. For further information, please contact Hanna Maula (hanna.maula@nesteoil.com).
