The Lyubov Orlova had been tied up in the harbour for more than two years before it was towed away last week to be scrapped in the Dominican Republic.
But the ship snapped its tow line and had been drifting toward open water when an offshore support vessel from Husky Energy reattached a line on Wednesday.
Sean Hanrahan, the port authority's president and CEO, says he's sent a letter to Transport Canada informing it that the port won't permit the vessel to berth at any of its facilities.
Hanrahan says that doesn't prevent the ship from coming back to St. John's because there are other facilities that are privately or Crown owned that may take the ship.
Transport Canada says the Lyubov Orlova was last reported about 70 kilometres north of the Sea Rose oil platform and it is making arrangements to determine the vessel's final destination.
