Liquefied gas ship safety. Analysis of the record 1964-1979
In spite of all the disaster scenarios that can be imagined involving LNG and LPG vessels, the large body of historical evidence on their actual safety performance reveals a record superior to that of crude-oil tankers. The casualty data on liquefied-gas ships, compiled from reports published in Lloyd's List, show that since 1964, only two cargo spills have occurred - neither resulting in serious consequences - and no cargos have caught fire. Only two serious incidents (where some risk of cargo leakage or fire appeared to exist) occurred during 1979: (1) on June 29, the El Paso Paul Kayser hit a submerged rock in the Straits of Gibraltar and, though the vessel lost 850 tons of steel, the cargo-containment system remained intact and (2) on April 8, the Mostafa Ben Boulaid sustained a 15-min spill through deck fractures caused by a construction defect in a safety valve, but the cargo tank itself was not damaged.
