Tank modification (existing tank 4.8 m x 3.3 m x 1.67 m)
Reduce tank capacity to about 75% of original by removing a section of the tank body.
Two U-shaped cuts through the 8 mm steel plate, each about 6.64 linear metres: Cut 2 removes the body section, Cut 1 releases the end plate, which must be kept for reuse.
Cut surfaces prepared and finished for correct alignment and fit-up before welding; end plate repositioned and continuously welded around the full perimeter (about 6.64 linear metres of weld).
