SEA-ICE CONSTRUCTION-SKID-MOUNTED PUMPING UNITS.
Abstract
Two skid-mounted pumps were developed for thickening natural sea ice in polar areas where air cargo space is critical and support equipment is limited. One is a high-pressure, lowvolume unit principally for confined flooding. The other is a low-pressure, high-volume unit principally for free flooding. Within limits, the units can be used for both types of flooding. Both units consist of a diesel-driven centrifugal pump mounted on a towable skid-base and enclosed in an insulated aluminum-paneled shelter fitted with access ports and an automatic shuttertype ventilation system. They are winterized for easy operation in temperatures to -40 F, and they are equipped with entry ports for preheating with a portable hot-air slave heater in temperatures below 10 F. Both units are air transportable in a ski-equipped C-47 aircraft, and they can be towed on snow and ice with equipment as small as an M-29C cargo carrier. No flooding gear is provided with the pumping units; this must be selected for the specific job requirement. (Author)
