Finnish refiner Neste Oil has estimated the costs in lost production and repairs from a fire at its new diesel production line to be around E40 million.

The fire broke out in early April due to a leak in the heat exchanger as the refiner was shutting the line down for maintenance. Neste has said that although maintenance and repair work will be ongoing throughout May, this will not impact upon its petroleum product deliveries.

Neste has invested E750 million in the project and the fire at the diesel line in Porvoo is the latest in a series of problems experienced since it opened in June 2007.
