The fire that took place at Neste Oil's production line 4 at the Porvoo refinery on Friday 4 April will delay the completion of the line's maintenance shutdown through May. The line, which was commissioned in summer 2007 and concentrates on diesel production, had just been prepared for a planned partial maintenance shutdown prior to the fire. This work was due to take place in April. Lost production resulting from the extended shutdown and the repair costs are expected to total approximately 40 million euros. The fire was the result of a leakage in a heat exchanger and lasted some 50 minutes. The fire damaged cabling and the table-top of the line's distillation column. Scheduled maintenance work on other units at the Porvoo refinery will also take place during April. Neste Oil's petroleum product deliveries will not be affected by maintenance work.
