Although deep-well cargo pumps have been used in the marine field for some time, their popularity has recently increased. This has been due partly to an increase in the bulk carriage of chemicals by sea, and partly in order to reduce the overall cost of ships, since this type of pump eliminates the need for a separate pump room. This article compares the advantages of the positive-displacement screw pump with those of the centrifugal pump. It also examines pumps with a submerged power source and compares these with pumps which are shaft-driven from a power source on deck. The author deals with units which can be used as the main cargo pumps on vessels up to 50,000 tons, carrying various kinds of liquid cargo in bulk. The pumping arrangements discussed are also suitable for coastal crude oil carriers, into which large super tankers may discharge. (AUTHOR)
