On October 12, 2006, at 2.32 p.m., according to the preliminary data, a leak developed that led to depressurization of the Vacuum Distillation column of the Vacuum Unit followed by hot bottom product release into the atmosphere. Due to the contact with atmosphere the self-ignition of the bottom product occurred. Because of the flame impact on the supporting structure of the vacuum column, the latter started leaning and fell on the heat exchangers block. Additional petroleum products released and further fueled the fire.

Emergency shut-down of the Vacuum Unit and Visbreaker was made, while the VGO Hydrotreatment Unit, FCC unit and MTBE Unit were subject to the routine shut-down. Fire rescue forces localized the fire and the fire was completely extinguished at 8.09 p.m.

Crude oil refining is continued. Current refining capacities of Mazeikiai Refinery are 12,000 tons per day, excluding the Vacuum unit. Currently all necessary incident remediation activities, and preparation for reinstatement of the previous capacities.

Damage suffered by AB Mazeikiu Nafta will be preliminary assessed upon completion of all necessary investigation activities.
