The work was done to replace the sidetanks that were rotted out due to the tanks not being coated. Also continous service through the Seaway locks caused a lot of wear at the hip and shoulders of the hull.

It was cheaper to replace the entire sidetanks as prefabricated units (in the Tim D. Dools' case her bottom tanks had been replaced a few years earlier), then to do repairs.

Increasing the width of the Tim S. Dool increased her cubic capacity from 1,298,364 to 1,360,900 cubic feet, but also allowed a deeper draft. Her Summer draft was 27'-1", and after rebuild, 28'-2".

Just to note that in the Algoville's case, that when she sailed as Senneville, she suffered a complete collapse of her double bottom structure in holds number 2 and 4 in 1989 due to the stress from loading iron ore at high rates and the way she was loaded over the years. That was the reason for the replacement of her double bottom at Port Weller in the Fall of 1989.

Canadian Ship Widening

When several Canadian vessels were widened years ago like the CSL Tadoussac, Tim S. Dool, Atlantic Huron, etc. Were these widening done to simply increase the buoyancy of the vessels to allow them to carry increased loads of high-density cargoes like iron ore or did the work include a complete reworking of the cargo holds as well?
