The world's most powerful icebreaker Siberia is being tested in St. Petersburg

During the mooring tests, which began on the first serial nuclear-powered icebreaker of Project 22220 Siberia, experts will check the build quality of its systems and life support devices, and will tune the equipment. Shipbuilders of the Baltic Shipyard carry out these works together with contractors with the participation of suppliers. In 2021, when equipment setup and testing are over, the world's most powerful icebreaker will be handed over to the customer. But first, «Arctic», the head vessel of this project, will be part of Atomflot.

According to the mooring test scheme, shipbuilders supplied power from the shore to the main switchboards of the icebreaker. Then test of the operability of the main systems, nodes and mechanisms began. The Baltic Shipyard performs these works in a short time for such a large and fundamentally new project. So, just recently, the formation of the hull and superstructure, which grew above the engine room of Siberia, was completed. After that, the experts made the installation of the turbo-generators, checked all the ship's electrical equipment.

At the same time, they continue the construction of the «Arctic», the lead nuclear-powered icebreaker and «Ural», the second serial icebreaker of this project. Moreover, under the terms of another agreement signed with Atomflot, shipbuilders will begin construction of two more vessels of a new type, expanding the entire series, which has no analogues in the world, to five units.
Such projects have gained popularity not only because they will be the largest and most powerful nuclear powered ships in the world, having received them, Russia will retain its leadership in the development of the Arctic. Each of them, thanks to the dual-draft construction, will be able to work both in deep water, providing for pilotage in the western sector of the Arctic and breaking ice up to three meters thick, and in shallow water - at the mouth of the Yenisei and the Gulf of Ob. Today, gas fields are being developed there and hydrocarbon processing projects are being implemented.
These universal giants with a length of 173.3 meters and a displacement of 33.5 thousand tons have a new generation RITM-200 reactor unit, more compact and economical, consisting of two nuclear reactors with a capacity of 175 MW each. And besides, the designers applied a number of new design solutions there, which allow to improve the layout of energy-efficient equipment and increase the operational characteristics of the vessel.
