The invention relates to Maritime transport, and in particular to underwater transport complex, enabling the carriage of goods in any season and at any ice conditions in the extreme conditions of the Arctic ocean.

Known transport system comprising: seaports surface-based journal "Military parade" No. 1, 2007, p.60, 61), ships with ice-breaking (Military Parade, No. 5, 2005, p.32), satellite navigation system. In extremely severe conditions of the North sea ports covered with ice, which makes mooring and complicates handling. Icebreakers solve the problem of transportation of goods, but in conditions of heavy ice have low cruising speed.

Known transport systems, including submarines for military purposes, based on the surface ports (the journal "Military parade", №1, 2006) and are able to move under the ice at large distances (the Journal "Military parade", No. 6, 2006, page 36) and having a navigation sonar system (Submarines. Shunkov, NR. M., ed. Potpourri, 2005. C. - 608, the journal "Military parade, No. 5, 2005, p.30). The advantage of submarines is a high cruising speed and the ability to move in a submerged position beneath the ice. But hydroacoustic navigation system does not provide safe is th scuba diving submarines. For example, submarines of the U.S. Navy from 1983 to 1987, he was involved in 56 collisions including foreign ships (the journal "Military parade", No. 4, 2006, p.50). The cause of reduced quality of the navigation sonar system, serve as "mirrors", "underwater lens and bubble screens, and reduced in the 4-5 range acoustic signals in shallow water.

Known construction submarines (invention 2078709 C1, 6 W 3/13, B63G 8/00; 2116926 C1. 6, WV 3/00, 3/13). The proposed structures are solved problems of strength. But technological capabilities for the transport of goods is very limited, both because of the complexity of loading and unloading.

The closest analogs can serve invention (2223887 C1 7, WV 3/13, B63G 8/00, 2051064 C1 In 3/13, D63G 8/00). Noteworthy is the modular construction of the SUBMARINE hull. However, the advantage of the modular design is that it can only be used to repair plants with deep modifications SQ. In the patent 2051064 presents a good layout of the cross-section of a SUBMARINE hull. But no constructive solution to load cargo in compartments.

Known systems underwater navigation VS 7/26, WV 22/22, RF patent 2155699 28.08.1996. Signal buoy is released from the hull of the sunken vessel. This buoy is equipped with a light and radiosignals device is effective only for tape and places the accident submarines (SUBMARINE).

The problem solved by the invention is the development of underwater transport system, including 1) ports capable of receiving cargo submarines (CSR) in a submerged position, to raise them to the surface position for loading and unloading operations and to send a boat from the port in a submerged position, 2) in developing the cargo submarines modular, each module of which has a functional purpose, namely power towing module, removable cargo module with continuous longitudinal compartments, providing fast including automatic unloading and loading of cargo, and tail module-fairing, 3) the development double row of underwater trails with shaped fairway in shallow waters and with a fixed axis of the track special signal underwater cable and 4) the development of a stationary underwater navigation system of the new generation.

The technical result of the invention is the use of sea water beneath the ice as a medium for the passage of cargo submarines in any season and in any weather conditions, high maneuverability CSR for automatic mooring cargo swivel lifting platform seaport, which fully provides the solution of the transport and energy security in the area of poberezh the Arctic ocean (SLO) and the East coast of the country.

The technical result is achieved by the fact that ports are 1) internal, ice-free water area; 2) equipped with a lifting-rotating platform, providing mooring for CSR in a submerged position, raising it to discharge in surface position, 3) high speed CSR under the ice, a wide range of technological capabilities and low cost of time for cargo handling, 4) interconnected underwater slopes; 4) underwater trails are equipped with underwater navigation system with three-fold redundancy.

In addition, the technical result, which is manifested in the expansion of technological capabilities in the carriage of goods, is that CSR is structurally made of three functional modules, while the head module is made in the form of towing power module, the average replacement cargo module is made with the possibility of placing at least two tiers of standard freight containers, or passenger modules, or a standard tank car transportation of liquid or gaseous goods, and end functional module is designed as a module-fairing and is tasked with ballast tanks. In towing power module and the tail module-fairing posted by retractable thrusters that provide the necessary maneuvering the th CSR at mooring on the cargo platform.

The technical result, which is manifested in traffic safety CSR with a large cruising speed, is achieved by the fact that towing power module is equipped with a combination of underwater navigation system, allowing both to have without surfacing constant communication with the traffic control center, and to have information about water, ice conditions along the entire route, as well as having information about the position of CSR on the road through communication with the receiving-transmitting devices attached to the cable, which is laid along the axis of the underwater route.

The proposed construction of the underwater transport of the complex as a whole may be a universal type of construction of sea ports, cargo submarines and submarine slopes, equipped with a three-fold redundant underwater navigation system that is a new universal solution in the movement of goods in the extreme conditions of the Northern latitudes and Eastern coast of the sea of Okhotsk.
