SUBSTANCE: invention relates to ship-building, specifically to enterprises intended for basing, technical inspection and renovation of vessels, as well as for initial operations connected with hydrocarbon production. Base of underwater oil-producing fleet includes administration and on-site facilities, dock, osmotron, railway station, airport with helipad. Dock is made with possibility of technical inspection of underwater vehicles which produce oil under drifting ice and represents transshipment point when oil is delivered by radio-controlled raiders in meshy containers which fill polymeric reservoirs with oil on dry-cargo vessels to deliver containers to oil refineries. Dock roof is equipped with snow-saving canisters from which melt-water can be used to raise water level in separate compartments of dock and to generate electric energy in hydraulic turbine.
EFFECT: base for underwater oil-producing fleet is organized to provide vessel technical inspection, crew rotation, replenishment of completion materials and to serve as transshipment point when oil is delivered by raiders to dry-cargo vessels.
The invention relates to shipbuilding, in particular to enterprises designed for home inspection and retrofitting of vessels and transhipment operations associated with hydrocarbon production.
Currently, an important issue is the reliable energy supply industry and settlements, while the key role of hydrocarbon resources, and as the depletion of their stocks on land, the exploitation of these minerals is transferred to the waters of the seas and, in particular, the shelf of the Arctic ocean, where their considerable reserves.
Recently, widespread method of oil extraction using oil platforms, but in the North where there drifting pack ice, this way is unacceptable.
It was therefore proposed underwater apparatus adapted for oil extraction under thick ice cover transport her in the spherical polymer containers, fill in mesh containers that tow detachable from the submersible raiders, controlled by radio .
However, if this were not disclosed questions based underwater vehicles and actions of the raiders after their separation from vehicles.
In this proposal we are talking about the organization base of the underwater oil fleet, where it is possible to ensure that the inspection of ships, shift crew, replenishment of materials and to serve as a transit point for the shipment of oil by the raiders on bulk carriers.
This takes into account that in Russia there are many rivers, originating in the South and flows into the North sea. These include such major rivers as the Ob, Yenisei, and Lena, in estuaries where low population density and poor infrastructure, and the sources of the rivers are large enterprises and transport communications. We propose to organize an overload of containers with oil on this basis with the raiders on bulk carriers, able to provide reliable delivery across the river to refineries (refinery) located in the South, where there is a possibility after deep processing of oil to send the oil on the existing highways to consumers.
Given the inappropriateness of empty journeys, it is proposed to download bulk carriers on the way back to the wood processing products in wood-processing enterprises (OPTIONAL), located in the lower reaches of the river, with their subsequent delivery to the ocean breakers in the port, located in the North.
The raiders also released from the containers will be returned to their underwater vehicles.
The problem of energy supply base is proposed to solve it at the expense of renewable resources, in particular in the conduct of large osmotron, installed in the mouth of the river, where the mixing of fresh river water with the salt water of the ocean . Additional environmentally friendly energy is offered to get through the roof of the dock, equipped with a system segobriga cans, meltwater from which, falling on a rotating turbine, will result in action hidroelectrostroy  and, in addition, will be used to raise the water level in the separate compartments of the dock.
Underwater vehicles are encouraged to upgrade due to the replacement of bioenergy engines biochemical (BCD), in which the empty holders in reverse tunnel lift through the use of polymer hydrogels, which makes them a very active element of the engine and thereby increasing their energy capacity . Considering the harsh Arctic climate , the upright support apparatus equipped with ice-cutters. The same engines and the ice-cutters are equipped dry-cargo vessels. In underwater devices adjusted mechanical compartment, where funds are available for the fabrication of polymeric containers for oil from billets supplied from refineries.
In the structure of the database in addition to the dock provides administrative complex, providing comfortable accommodation for staff, crew boats and their families. In the same complex provides automated control system (the SU), ensure synchronization of all processes and rational use of resources and energy base. In addition, on the basis of available warehouses, railway station, airport with helipad and a common unit.
