-The poor development of transport infrastructure in the Arctic is the cause of significant time losses and increased costs when delivering goods to points located on the coast and islands of the Arctic Ocean and its seas. Often, a helicopter is a way of unloading a ship, which is the only way to deliver cargo to the necessary places. The search for the optimal geographical location for unloading a vessel using a helicopter is an urgent task, since such way of unloading a vessel is very expensive. The mathematical model of finding a geographical location for maximally profitable transportation of cargo from a cargo vessel using a helicopter to the necessary points of unloading is developed in the work. Using the example of a developed model, it has been shown that it is possible to obtain economic benefits when transporting goods in the Ob Bay.
