In Kronshtadt, at the Dock named after Veleshchinsky, the malfunctioning electric propulsion motor will be replaced, he states.

Aleksey Rakhmanov says the engine manufacturer is to bear the repair costs.

“Those who supplied the defective unit will pay, I suppose. However, the Arktika icebreaker is actually an R&D product fitted with frequency converters for the first time ever,” stated the head of United Shipbuilding Corporation.

The icebreaker is to engage in sea trials by the end of July and be deployed in the 2020-21 winter navigation season, the speaker said.

The Arktika left St. Petersburg on 23 June 2020 for the final phase of sea trials.

Project 22220 Nuclear powered icebreakers are fitted with two 175 MW RITM-200 reactors. Project 22220 ships will be the biggest and most powerful icebreaker with nuclear power (60MW) in the world. 
The dual-draft design of the vessels enables them to be worked both in the Arctic and in the mouths of the polar rivers.

Two RITM-200 reactors will fuel the ice-breaker.

The icebreakers built by CDB Iceberg in 2009 will work in the western Arctic region: in the Barents, Pechora and Kara Seas, as well as in the shallower areas of the Yenisei estuary and the Ob Bay region.

Arktika is named after the first surface ship to reach the North Pole, an earlier nuclear-powered icebreaker.
