Kirov Energomash Plant to manufacture two steam turbine units for third and fourth brand-new nuclear-powered ships

The plant aims to transfer the first PTU-72 steam turbine unit to the customer by the end of 2022, and the second by the end of 2024.

Kirov Energomash has been involved in the construction of the world’s largest and most powerful nuclear icebreakers since 2013, developing steam turbine units for the vessels. The units are designed to provide power to each icebreaker’s three 60 MW electric propulsion motors and on-board systems. The unit comprises two main turbine generators with a capacity of 36 MW each.
Kirov Energomash has already supplied turbines to the Baltic Shipyard for the leading icebreaker Arktika and for the first in a series of nuclear-powered ships, Sibir. At the plant’s testing facility, preparations are currently underway for acceptance tests on the main starboard-side turbine generator for the second in the series of icebreakers, the Ural. The port-side generator is on the assembly line in the MX-8 workshop. At the same time, Kirov Energomash staff are installing and commissioning equipment on the icebreakers, and are also participating in the mooring and sea trials of the vessels.

In addition to the PTU-72, in 2015–2017 Kirov Energomash designed, manufactured, and tested TNA-10 turbocharging units for the anti-icing devices of three Project 22220 nuclear icebreakers, which were then shipped to the Baltic Shipyard. These devices supply compressed air along the sides of the ship to stop the hull from being covered in ice. This also improves its icebreaking abilities. Kirov Energomash will manufacture similar units for the third and fourth icebreakers in the series. The supply contract with the Baltic Shipyard is currently under negotiation.
