Analysis of information sources in references of the Wikipedia article "Manolis L" in English language version.
The Manolis L, a paper carrier, sank in Notre Dame Bay in 1985 with 150,000 litres of oil aboard. Early last month, work began to remove that oil using remotely operated underwater vehicles, or ROVs, to avoid risks to human divers and allow for longer dives.
The cleanup is a complicated process, involving specialized equipment and skills that could have to be sourced from elsewhere in the world.
Documents obtained by CBC News show the agency wanted to know how much it would cost to remove all the oil still in the Manolis L, but the results are blacked out.
It takes the divers about one hour to get down to the Manolis L. because they have to stop and adjust for the pressure, they work for about 30 minutes and then it takes about an hour and half to come back up to the surface.
When the Manolis sank, it took an estimated 462 tons of Bunker C fuel, 60 tons of diesel and 22.5 tonnes of lube oil to the bottom. How much remains on board isn't clear, but the information gleaned from the assessment will help plan how best to remove what is there.
The Coast Guard has been monitoring the wreck in the years since, patching things up and catching some of the oil that was escaping. But the thought of it breaking open in a harsh winter storm was a constant worry among residents.
The Manolis L, which sank to a depth of more than 70 metres in 1985 off the coast of Newfoundland and Labrador, lay dormant until April 2013 when cracks in the hull, coupled with a powerful storm, allowed some fuel oil to reach the surface.
