The resulting explosion killed a worker, severely injured another and caused heavy damage to the building. A safety analysis was not required at the time, and none was performed during the planning, design or construction of the facility. National fire codes were changed as a result of the accident. January 19, 2004, Skikda, Algeria. Explosion at Sonatrach LNG liquefaction facility. 27 killed, 56 injured, three LNG trains destroyed, a marine berth damaged. 2004 production was reduced by 76 percent. Total loss was US$900 million. A steam boiler that was part of an LNG liquefaction train exploded, triggering a massive hydrocarbon gas explosion. The explosion occurred where propane and ethane refrigeration storage were located. Site distribution of the units caused a domino effect of explosions. It remains unclear if LNG or LNG vapour, or other hydrocarbon gases forming part of the liquefaction process initiated the explosions. One report, of the US Government Team Site Inspection of the Sonatrach Skikda LNG Plant in Skikda, Algeria, March 12–16, 2004, has cited it was a leak of hydrocarbons from the refrigerant (liquefaction) process system. Security concerns On 8 May 2018, the United States withdrew from the Joint Comprehensive Plan of Action with Iran, reinstating Iran sanctions against their nuclear program. In response, Iran threatened to close off the Strait of Hormuz to international shipping. The Strait of Hormuz is a strategic route through which a third of the world's LNG passes from Middle East producers.
