Liquefied natural gas
"El Paso Sonatrach" was along with her sister ships "Paul Kayser" and "Consolidated" built in Dunkirk, France in 1977. They all operated out of the Consolidated Natural Gas Company Cove Point LNG import facility (now owned by Dominion Resources) in the Chesapeake Bay, Maryland. Liquefied natural gas (LNG) was loaded and shipped from a Sonatrach facility in Arzew, Algeria.
