Parbuckle Salvage Used Raising the USS Oklahoma

From Wikipedia.

I came across a photo of the Navy raising the USS Oklahoma in Pearl harbor during the war.  This meant turning it over to an upright position and the caption mentioned Parbuckle Salvage as the method used.

Parbuckle Salvage uses rotational leverage and is commonly used on smaller vessels that a battleship, but has been used on larger ones.

In 1943, the USS Oklahoma was rotated nearly 180 degrees.    It was also used on the USS Utah, but as it was being rotated, its hull caught the harbor bottom and it slipped toward Ford Island and the effort was abandoned.

Parbuckle Salvage was also used to right the ocean liner MS Costa Concordia in the Mediterranean recently.
