Just after midnight on May 6, 1968,
while loading petrol at Ensenada, La Plata,
the Argentinian motor tanker Islas Orcadas
was destroyed by a massive explosion and sank alongside the pier.
Burning debris from the wreck rained down
upon two other Argentine tankers in the vicinity,
Fray Luis Beltran and the Cutral Co,
both of which loaded with oil also caught fire, exploded, and sank.
Shore installations also sustained heavy damage.
The fire started in a hose being used to pump petrol on board
the Islas Orcadas, which had already loaded 12,000 tons at the time.
Four crewmen were lost in the blast,
which also shattered every single window
within a radius of over two miles,
while another two men were injured.
Fortunately most of the crew memebers of all three tankers
had been on shore leave at the time.
