The Greek motor tanker Theodegmon,
which sailed from the River Orinoco port of Puerto Ordaz
on October 6, 1983,
bound for the Manchester Ship Canal terminal of Eastham,
loaded with 33,629 long tons of Venezuelan crude oil,
ran aground on a mudbank that contained rocks
at Mile 175 in the River Orinoco,
16 miles downriver, just over one hour later
due to strong current.
Three tugs were unable to refloat the vessel.
However, after a quantity of her cargo
had been discharged into barges,
the Theodegmon was eventually pulled free
on October 22 by five tugs.
She then proceeded to Jacksonville to be drydocked.
With severe bottom damage being found,
she was declared a contructive total loss.
