ICE CONSTRUCTION - EXPERIMENTAL SUBMERSIBLE ELECTRIC PUMP FOR FREE FLOODING.
Abstract
Investigations on leveling and thickening floating ice sheets by surface flooding at Point Barrow, Alaska, between 1958 and 1960, resulted in the development of a free-flooding technique for improving relatively smooth, natural sea ice. In this technique, the flood water is discharged around the pump and allowed to seek its own boundary. An elevated diesel-enginedriven pump was used to test this technique at Point Barrow; its disadvantages resulted in the development of an experimental 1600-gpm, 15-foot-head, 16-foot-long, 16-inch-diameter, electric-motor-driven submersible pump for free flooding. Tests on the experimental pump at North Star Bay near Thule, Greenland, showed that a submersible pump was well suited for free flooding. It was simple to install and recover, it required no priming and it was easy to keep ice-free during periods of non-use. These tests resulted in the development of an improved submersible pump for free flooding; currently, a prototype of this pump is being fabricated for field testing. (Author)
