MV María Alejandra
MV ''María Alejandra'' was a Spanish oil tanker built in 1975 at Cádiz, Spain. She sank suddenly on high seas some off the coast west of Nouadhibou, Mauritania, on 11 March 1980 after several internal explosions, presumably related to malfunctions in the inert gas system. Of the 43 people aboard, 36 perished. She was the penultimate ship built by Astilleros de Cádiz, Cádiz, one of the main shipyards in Spain. Before its completion the original customer, the Italian company D'Amico Società di Navegazione, canceled the contract.

Incident On 4 March 1980 ''María Alejandra'' arrived in Algeciras Bay and unloaded the oil the vessel brought from the Persian Gulf at the CEPSA refinery. During unloading, the crew found pro ...

There are two basic types of oil tankers: crude tankers and product tankers. Crude tankers move large quantities of unrefined petroleum, crude oil from its point of extraction to oil refinery, refineries. Product tankers, generally much smaller, are designed to move refined products from refineries to points near consuming markets. Oil tankers are often classified by their size as well as their occupation. The size classes range from inland or coastal tankers of a few thousand metric tons of deadweight tonnage, deadweight (DWT) to ultra-large crude carriers (ULCCs) of . Tankers move approximately of oil every year.UNCTAD 2006, p. 4. Second only to pipeline transport, pipelines in terms of efficiency,Huber, 2001: 211. the average cost of transport of crude oil by tanker amounts to only US.

Inert Gas
An inert gas is a gas that does not readily undergo chemical reactions with other chemical substances and therefore does not readily form chemical compounds. Though inert gases have a variety of applications, they are generally used to prevent unwanted chemical reactions with the oxygen (oxidation) and moisture (hydrolysis) in the air from degrading a sample. Generally, all noble gases except oganesson (helium, neon, argon, krypton, xenon, and radon), nitrogen, and carbon dioxide are considered inert gases. The term ''inert gas'' is context-dependent because several of the inert gases, including nitrogen and carbon dioxide, can be made to react under certain conditions. Purified argon gas is the most commonly used inert gas due to its high natural abundance (78.3% N2, 1% Ar in air) and low relative cost. Unlike noble gases, an inert gas is not necessarily elemental and is often a compound gas. Like the noble gases, the tendency for non-reactivity is due to the valence, the ou ...
