Arctech Helsinki Shipyard

Arctech Helsinki Shipyard was established as a joint venture between STX Finland, a subsidiary of STX Europe, and the Russian state-owned United Shipbuilding Corporation (USC). The new shipbuilding company started its operations at the Hietalahti shipyard on 1 April 2011. On 28 October 2013, it was reported that USC was going to buy the remaining shares from STX Europe and become the sole owner of the company. The sale was finalized on 30 December 2014 and the United Shipbuilding Corporation has been the sole owner of Arctech Helsinki Shipyard since the beginning of 2015.

The Russian ownership has resulted in some issues due to the economic sanctions imposed by the European Union and the United States as a response to the Russian involvement in the unrest in Ukraine. In August 2014, the Nordic-based bank Nordea announced that it would terminate Arctech's accounts due to the financial sanctions imposed by the United States, forcing the shipyard to switch to another bank.

In early 2018, it was reported that the United Shipbuilding Corporation was looking for a new majority owner for Arctech Helsinki Shipyard in order to circumvent the sanctions. The Finnish shipyard, which had not received any new orders since 2016, had become an economic burden for the Russian owner with cumulative loss of 156 million euro in 2011–2015 after which the company stopped reporting its economic situation. Initially, it was reported that the Croatian investment corporation KERMAS Group would purchase a 55 percent share of Arctech Helsinki Shipyard with the USC remaining as a minority shareholder. However, in September 2018 the president of the United Shipbuilding Corporation, Aleksey Rakhmanov, stated that the company was instead negotiating the sale of the whole shipyard with three parties: a group of Norwegian companies, an unnamed Russian businessman, and the KERMAS Group which had previously declined partial ownership. In October 2018, it was announced that the shipyard would be sold to the owners of Nevsky Shipyard and, in addition to cash, the sale would include transferring the privately owned Saint Petersburg-based shipyard to the state-owned United Shipbuilding Corporation. While the initial deal fell through at the very last moment reportedly due to lack of approval from the Russian authorities, the sale was finally authorized by the Russian government in April 2019.

On 15 May 2019, Arctech Helsinki Shipyard officially announced the change of ownership of the shipbuilding activities in Finland by the end of the month. In preparation of the transaction, a new shipbuilding company Helsinki Shipyard was established to take over the assets and operations at Hietalahti Shipyard. It was then sold to Algador Holdings, a private Russian company owned by Rishat Bagautdinov ja Vladimir Kasyanenko, while Arctech would remain as a fully owned subsidiary of the United Shipbuilding Corporation and continue shipbuilding operations in Russia as a shareholder of the Nevsky Shipyard. Victor Olerskiy, the former deputy Russian transport minister and the former head of Federal Agency of Maritime and River Transportation, was appointed as the chairman of the board of the new company. The transaction, which included 35 million euro and 49.99% ownership of Nevsky Shipyard, was finalized on 20 May. In September 2024, The Moscow Court of Arbitration suspended Arctech's corporate rights in relation to Nevsky Shipyard following a request from the Russian Ministry of Industry and Trade.
