The Canadian Press was able to get the May 2013 report into the tow issues with HMCS Athabaskan. I have not seen the report, so the info below is from the CP Piece. The report, obtained under access-to-information law, says the punctures require 18 square metres of steel to be replaced. Another 711 square metres of the ship needs fresh hull coating because the broken lines rubbed against the vessel, while rails, stanchions and a smashed sonar operator compartment window also have to be replaced, the report says.
the repairs would cost approximately $2 million.
The report says the Defence Department was invoiced about $546,000 by Atlantic Towing to complete the tow from Sydney, N.S., to Halifax, on top of the $707,000 the department has been billed for the initial leg of the journey by original Contract winner Group Ocean.
Investigators say the Ocean Delta,one of the two tugboats involved in the operation suddenly lost power in the Gulf of St. Lawrence between Sept-Iles, Que., and the Magdalen Islands on the morning of Dec. 26 when an air leak caused the clutch to disengage. The tug then spins around, striking the navy ship along one side while its fenders “burst as a result of the force exerted on them during the collision,” the report says.
On the 28th, the tow to Halifax resumed. Then, over a course of hours, four lines snap while the ship is about 10 kilometres off the rocky coast of Scatarie Island. The report says winds did not exceed 45 kilometres per hour and waves were between one to two metres at the time.
The first tow line snapped at 10 p.m. A search and rescue helicopter was deployed by the Joint Rescue Co-ordination Centre to bring personnel onto the drifting ship to secure a new line, which was done early on the morning of Dec. 29.
That tow line snapped about five hours later, and then a mooring line was used to continue the tow. But that line also broke a few hours later, and another mooring line was attached.
On Dec. 30 at about 3:40 a.m., that line broke. A third mooring line was then attached to HMCS Athabaskan to return it to Sydney.
