On October 4, 1990, the Rio Orinoco, a tanker with a gross tonnage of 6000 tons, left Amway Bay in Venezuela loaded with 9000 metric tons of liquid asphalt destined for Montreal, canada.
On October 15, 1990, the Rio Orinoco, in transit thru the Gulf of St. lawrence, began experiencing mechanical problems. In the hours that followed, the crew tried to make repairs but without much success. The ship's captain, therefore, decided to leave the usual channels and head for an anchorage near Port Meunier on Anticosti Island. During the night a strong wind came up, abd the ship began dragging its anchors. At 0430 local time on October 16, 1990, the ship notified the Canadian Coast Guard that it had run aground and was leaking from the bottom of the ship.

Jacobsson of IOPC in same Proceedings says "experienced problems with her main engine". Claims 185 tons of the 300 tons of bunkers onboard was spilled. IPOCF DB also has this figure.

The ship spilled 200 tons of bunker oil on Anticosti Island, a nature preserve. Engine room somehow flooded. Salvors were unable to refloat the vessel during the winter. Ship was declared a total loss. It was not until August 1991, the wreck was removed. Would have been a much bigger spill except that asphalt had gone solid, and had to be reliquified in order to lighten the ship.

CTX has no evidence that anybody tried to determine the nature of the mechanical problems.
