The study's authors put the questions and answered them consistently.
Some of formulated answers to the questions below.
. For some regions of the world is rational transportation of icebergs? - For all countries with urgent need for fresh water. These are primarily large arid areas of the Southwest U.S., Mexico, Chile and some parts of North Africa, and Australia. In addition, there will undoubtedly be interested in such densely populated regions such as Japan. Equally important is the fact that the country, transporting icebergs have access to the sea, and that led banks to their waterways depth of at least 200 and preferably 300 m
What are possible ways of transporting icebergs? - Icebergs have been known to swim. Therefore, they can easily take in tow. Need for their loading and unloading there. To how to better use tugs and their crews work should combine several icebergs in the "caravan".
Should look like the most economical, "Caravan"? - Cost-effectiveness calculations showed that the cost of transporting 1 m 3 of ice will be the smaller, the longer the "caravan". However, this pattern no longer applies to "Caravan", whose total length exceeds 20 km, as their towing any additional cost does not.
The most economical size of this "Caravan" width -300-600 m of sediment -300 m, length - 20 km and about 90 km. Such a "caravan" rises above the water about 50 meters to ensure that during transportation is not overturned, the length and width of individual icebergs should be greater than their height. Icebergs width less than 200 m hardly suitable for transportation, because during the riots, they can break up the waves scattered them far away parts of the sides.
Transportation icebergs too bizarre shapes, characteristic of the northern seas, are associated with high transport costs due to high water resistance. Thus, speaking of the transport of icebergs, we mean only the gigantic "table" icebergs.
