Oil giant BP paid an extra $500m to cover claims from the victims of an explosion at one of its refineries in Texas last year.
It has already allocated $700m for the March 2005 blast, which killed 15 people and injured 180.
BP said it had started the "phased re-commissioning" of the explosion-hit Texas City oil refinery in March.
