The historic SS William A. Irvin will be dry-docked for restoration on Thursday.

Restoration on the retired ore boat will take up to two months, according to a news release from the Duluth Entertainment Convention Center. Because of the unknown length of restorations, the floating museum's historical and haunted tours won't be available for the rest of the year.

Negotiations on restorations started this spring, when Fraser Shipyards and the DECC couldn't agree on a contract cost.

The Minnesota Historical and Cultural Heritage Grant and a match from the DECC funded the project's total budget of $504,000, said Chris Johnson, marketing coordinator for the DECC. But only $440,000 in work is planned at the moment, as leftover funding will be used in the event of additional work they may come across.

The final restoration plan includes funding for moving the ship to and from dry docks, fees associated with dry dock, blasting and coast the hatch crane, and fixing the steel around the waterline where it's thinning.

During its time at the dry docks, they're prioritizing work on the thinning steel and on any other features that can only be completed at the docks, Johnson said.

A more defined timeline for ship restorations will be available once the ship is evaluated in dry docks. Weather may also influence the timeline.

The ship hasn't been in the Minnesota Slip since September, when it was towed to Fraser in Superior.
