In May this year FSUE “Rosmorport” announced a tender for the construction of two vessels. Among the potential contenders for the victory were then named PSZ "Yantar" in cooperation with other shipyards, the site of the PSZ "Pella" Pella Sietas, where an 18 MW icebreaker is already being built for Rosmorport, Helsinki Shipyard Oy (former Arctech Helsinki Shipyard, which commissioned the icebreaker in 2016 for LNG Polaris.

But in the end one application was submitted for the tender - from JSC Onega Shipbuilding and Ship Repair Plant.

The application was recognized as meeting the requirements. "To conclude a contract with JSC OSSZ at the price proposed by the participant of the tender," - says the final the procurement protocol.

The technical design of the two icebreakers was developed by the Baltsudoproekt Central Design Bureau, which is part of the Krylov State Scientific Center. The icebreakers must be equipped with two 6.5 MW rudder propellers, have an unlimited navigation area and operate year-round in the Baltic, White and Barents Seas, as well as in the Pacific Basin.

In the summer-autumn period - in the seas of the Arctic Ocean and river mouths. Length - 95.6 m, width - 22.5 m, draft - 8 m, ice class - Icebreaker7, ice passability - 1.5 m, speed - at least 16 knots. Autonomy for diesel fuel reserves - at least 20 days, for LNG reserves - at least 5 days.

This is the first Russian project of an icebreaker with a power plant capable of operating on LNG, vessels of this type have not yet been built in Russia, the Rosmorport noted. They also add that these will be the world's first LNG icebreakers with the DYNPOS-2 dynamic positioning system.


On the part of bmpd, recall that in 2020 it was reported that the Baltsudoproekt Central Design Bureau, part of the Krylov State Scientific Center (KGNTs), completed the development of a technical design for a dual-fuel icebreaker of project 23620. This is the first Russian project of an icebreaker with a power plant capable of operating on a liquefied natural gas (LNG).

The project was developed as part of the implementation of the Comprehensive Plan for the Modernization and Expansion of the Main Infrastructure, which provides for the construction of two icebreakers with a capacity of about 12-14 MW ice class Icebreaker7 for the seaport of Arkhangelsk and seaports of the North-Western (Baltic) basin. New icebreakers are needed to ensure year-round operation of the freezing seaports of Russia, as well as to replace icebreakers that have reached their end of life.

By order of FSUE "Rosmorport" specialists of the Central Design Bureau "Baltsudoproekt" developed a technical design of an icebreaker operating on two types of fuel (diesel and LNG), with a capacity of 13 MW, project number 23620. Representatives of the customer, a potential manufacturer of LNG equipment and Russian Maritime Register of Shipping.

Project 23620 is notable for being the first Russian icebreaker with an LNG-powered main power plant. The Finnish Polaris is currently the only operating LNG icebreaker in the world. Project 23620 is also the world's first LNG-powered icebreaker with the DYNPOS-2 dynamic positioning system.

The auxiliary icebreaker of project 23620 is designed for icebreaking support of winter navigation, icebreaking operations in port and near-port waters, berthing areas and auxiliary operations when mooring ships. Also, the icebreaker can be used for independent pilotage of ships and vessels (ship caravans), including in the summer-autumn period in the seas of the Arctic Ocean and in river estuaries, towing ships and other floating structures, participation in emergency rescue operations and in rendering assistance to ships in distress in ice conditions and on clean water. In addition, the vessel can be used to transport cargo, passengers and special personnel, to provide underwater technical work using crane equipment, a small-sized remote-controlled underwater vehicle and a diving complex,

The vessel has an unlimited navigation area with year-round operation in the Baltic, White, Barents and Pacific seas. It can be operated in the seas of the Arctic Ocean in the autumn-summer period.

To ensure reliable operation in various operating conditions with redundant capacities, the main power plant of the icebreaker includes four main diesel generators, one parking diesel generator and one emergency parking diesel generator. For the storage of LNG in the main hull of the vessel, there are two tanks of type "C".

The propulsion complex of the project 23620 icebreaker includes two Azipod propellers with a total capacity of 13 MW. In the bow there are two tunnel-type thrusters. The pulling force of an automatic double-drum towing winch with a cable-laying machine reaches 110 tons. In the aft part there is a cargo deck, which can accommodate 10- and 20-foot containers. In the bow there is a platform for receiving cargo from helicopters.

To improve the living conditions on the ship, premises for various purposes are provided, including a conference room, a salon, a sports and recreation complex. To ensure the delivery / rescue of people, including in ice conditions, the icebreaker is equipped with a hovercraft and collective survival kits. The vessel is also equipped with a pneumatic device with an inclined ramp and a platform for carrying out rescue operations and lifting rescued people from the water.

During the development of the project, the specialists of FSUE "Krylov State Scientific Center" carried out a full range of model tests on their own experimental base, including blowing in a wind tunnel. Icebreaking characteristics, including the ability to overcome continuous flat ice 1.5 m thick, are confirmed by duplicate tests of the Federal State Budgetary Institution "

Reconstruction plan of the Onega shipbuilding and ship repair yard

According to the web resource "Media Deck", about 5 billion rubles will be allocated from the federal treasury to the digital shipyard of the Onega shipbuilding plant in Petrozavodsk [JSC "Onega shipbuilding and shiprepairing plant", since 2014 is subordinate to FSUE "Rosmorport"]. The head of Karelia Artur Parfenchikov announced this at a meeting of the government of Karelia on July 16, 2021. According to him, a supervisory board has already been created, which includes competent people.

On July 27, together with the Security Council of the Russian Federation, a meeting will be held in Moscow on the creation of a digital shipyard in Karelia. It will be the first in Russia.

The first tranche - 500 million rubles - will be received in the second half of the year.

Recall that in August 2019, the estimated cost of the reconstruction of the Onega shipbuilding and ship repair plant was estimated at 5.3 billion rubles. This was stated in the procurement documents for design work.

"Creation on the territory of JSC" OSSZ "of a modern, high-tech, compactly located, environmentally friendly special complex for the construction, modernization and repair of ships, as well as the infrastructure of digital support for the construction of ships of the annual calculated production program. <...> The estimated estimated cost of the construction of the facility is 5.3 billion rubles in prices of the respective years (including VAT), including the cost of design and survey work, "- said in the procurement documents.

The project will be implemented in the period from 2021 to 2024. In parallel, an integrated digital production information system will be created at the plant, which will unite all the shipyard's divisions and transform their business processes. The goal of the system implementation is the transition to highly efficient shipbuilding management, as well as training personnel to work in digital production.

It is planned that after the completion of the modernization and digitalization of the enterprise, its productivity will increase several times, and the high-tech shipyard project itself can be replicated at other enterprises of the Russian shipbuilding industry.

The project documentation was developed by the St. Petersburg State Maritime Technical University and JSC "Center for Shipbuilding and Ship Repair Technology" (St. Petersburg). The development was financed by FSUE "Rosmorport".

On the part of bmpd, we recall that in early July it became known that JSC Onega Shipbuilding and Shiprepairing Plant received a contract in the amount of 18.5 billion rubles for the construction of two innovative dual-fuel icebreakers with a capacity of 12-14 MW of project 23620 for FSUE Rosmorport, with delivery in 2024. Obviously, getting an order for the construction of two icebreakers is closely linked to the plans for the reconstruction of the enterprise.
