Mystery Ship as Wharf

[Fairlane500]

To kill time I occasionally start poking around at aerial images, and recently I came across this hulk making up part of a pier at Algoma Steel in Sault Ste. Marie, Ontario, Canada.

I was wondering if anyone has an idea into her identity, I just thought it would provide an interesting bit of detective work.
My best guess is she is an old laker, which would seem pretty intuitive judging by the location. Aerial photos show she's been there since 1998, however that's as far back as I can get imagery for. In addition, measurements show her to be about 615 feet long, with somewhere around a 60 feet beam.

I can't help you with the identity of this one but it is quite a common practice in the Great Lakes to use old lakers as wharves and breakwaters. Despite being built of steel, in the fresh water environment their useful life just goes on and on
There are a few ships and tugs around up there that are still operational over 100 years old.

Thanks for the info.

To try and help solve the mystery, this should be a little help.
Behind the Yucatan, the main subject of the following photo, the hulk can be seen, with her name still present on the hull. The only task is to decode what it says...

EDIT: Mystery solved!
I plugged around with some combinations, and lo and behold, an answer arose. She is the former ore carrier Sewell Avery (IMO: 5321461), built in 1943.

Here's a picture of her in her batter days:
