It was realized on December 6, 1961,
with the shipment to Japan of 50,000
barrels of butane and propane as refrigerated
liquefied petroleum gas, the first large
commercial shipment of such gases in this form.
On that day the oil industry also chalked up two
other "firsts." The new Aramco plant at Ras
Tanura's Marine Terminal was the first facility
ever designed and constructed specifically to
refrigerate propane and butane for shipment by
ocean tanker. The Japanese tanker, Gohshu Maru,
which carried the chilled liquid to Japan,
was the first ship ever designed and built for
the express purpose of carrying refrigerated LP
Gas.
