The asymmetric icebreaker Baltika was accepted into the Russian fleet (photo, video). Innovative icebreaker vessel Baltika is ready to be handed over to the Russian rescue fleet Asymmetric icebreaker

Asymmetric icebreaker Baltika accepted into Russian fleet(PHOTO, VIDEO)

On February 20, 2015, a ceremony of raising the Russian flag took place on the, speaking in official language, multifunctional rescue diesel-electric vessel "Baltika". Why is Baltika unique? First, the asymmetrical body contour.

Secondly, the ability to go semi-sideways in the ice, which gives an almost twice as wide channel, 50 instead of 25 meters for a conventional icebreaker of similar dimensions. The 50-meter channel allows free passage for commercial ships. There is a second bridge for "oblique" movement.

Project R-70202 innovative icebreaker for oil spill response and rescue operations was developed by the Finnish company Aker Arctic Technology. The icebreaker was created in two stages. Laid down in June 2012 at Yantar in Kaliningrad, then, a year later, the main parts were transported to Finland to Arctech Helsinki Shipyard for assembly. The first tests took place at the beginning of 2014, and in May it was accepted by the state commission.

The icebreaker is equipped with special equipment for oil spill response, fire fighting, and environmental monitoring. It is capable of moving in flat ice 1 m thick. The length of the vessel is 76.4 m, the width is 20.5 m, the draft is 6.3 m, the power of three diesel generators is 7.5 MW, the speed is 14 knots, the speed is flat ice 1 m thick - 3 knots. The total is 7.5 MW. Crew - 24 people, special personnel - 12 people, autonomy - 20 days (24 people).

Rescue ship "Baltika" - asymmetry is not a vice

Baltika is not an ordinary project. Initially, when the construction of the ship had just begun, some spoke of it with some irony, mainly due to the fact that the term asymmetric was often confused with the word “curve” or “oblique”, which is not very close to the truth. And actually this asymmetry itself became calling card project.

“If the ship looks like a freak, then it will be operated - ugly! The lesson of "priests" did not go well (or maybe modern Internet designers have not heard anything about them).
(comment to the news "Korabel.ru")

To make fun of the design of the icebreaker, when photographs and videos appeared on the network, on which you can clearly see that the ship is not just another “myth”, but the most utter reality, gradually ceased. But shipbuilders and simply interested people found another reason to lament and make fun of the domestic ship industry. However, this is more likely not discontent and aggression, but an ordinary statement of fact with a slight degree of sadness and self-irony - they say, “Baltika”, although ours, was only built by the Finns. And no excuses about the supply of body parts with domestic enterprises and the excessive workload of the shipyards of our country, advocating for Russian shipbuilding, cannot be pacified.

So, at the conference "Russian Shipbuilding", which was held in St. Petersburg in April 2014, the head of CJSC "TsNIIMF" Sergei Buyanov in his welcoming speech noted that the "Baltika" is certainly a unique ship of its kind, but still “I would like such ships to be built at our domestic factories”.

But be that as it may, this is a topic for a separate discussion, and the new icebreaker is almost ready to work "one hundred percent". And those who were present at the sea trials could personally make sure that a slightly non-standard approach to design still became a kind of breakthrough.

And although the project has received its material embodiment only now, as we were told by Aker Arktic, which is the developer of the Baltika project, the idea of ​​an asymmetric icebreaker was born in the late 90s, when the requirements for icebreaking support for the fleet of the Baltic Sea were analyzed.

By the end of 1996, the idea of ​​creating a lagging icebreaker was developed, and in 1997 the first model tests of the ARC 100 project were carried out. “Later, a decision was made to build an oil terminal in Primorsk. At the same time, the idea came up to use the ship to deal with oil spills., the company said.

Further development work on the project continued in cooperation with the Finnish Maritime Administration, the Finnish Environmental Institute and ABB, with partial funding from the Finnish Technology Fund. As a result, the updated project was presented to the administrations of Finland and Russia in 2003. The Ministry of Transport of Russia made an order for the construction of the vessel when signing the contract in 2011.

In general, a ship like the Baltika could have been built even earlier. About this, when "Korabel" visited "Aker Arktic" (see the article "Shipbuilding in Finland. Part 2: "Aker Arctic" - "It is difficult to prove the advantages of an innovative approach"), said the sales director Arto Uuskallio: “We had the opportunity to implement this idea earlier, but the Customer then last moment preferred the traditional ship concept. This is an advanced development, and conservative thinking is practiced in shipbuilding. It is difficult to prove the benefits of an innovative approach.”.

“In general, the emergence of such a project has become a kind of response to an increase in the number of tanker traffic in the Gulf of Finland”, - note in "Aker Arktic". The asymmetric icebreaker is a continuation of the tradition of using the stern-forward method of moving through ice on ships. In practice, Baltika, due to the fact that moving forward at an angle to the diametrical plane, makes a channel 50 meters wide, replaces the work of two icebreakers.

Aker Arktic has patented the idea of ​​an asymmetrical ship hull. There are no analogues in the world, project developers note. And Baltika is the first ship built according to the ARC 100 project. “At the moment, the project has been expanded to the level of a reinforced version designed for harsher working conditions in the Arctic”, the company said.

“The secret of the uniqueness of the creation of the concept of the vessel lies in an integrated approach to solving problems. This is a multifunctional icebreaking vessel. It is ideal for year-round oil spill response, escort operations, emergency towing, firefighting and monitoring. environment» , - noted in the Finnish company.

The vessel is equipped with a diesel-electric plant with three azimuth propellers - one of the devices is located in the bow, the second in the stern and the third on the side in the stern of the hull. This solution provides efficient work vessel when moving bow, stern and log. Rudder propellers with a total capacity of 7.5 MW also help in the work of Baltika. The rescue vessel has a double bottom, a continuous main deck and tween deck, and a forecastle. Superstructure with residential and office space located in the bow of the "Baltic".

The vessel is capable of moving in even ice 1 m thick both bow and stern forward and at an angle, laying a channel up to 50 m wide in even ice 60 cm thick. For comparison, according to some reports, the diesel-electric icebreakers Moskva and St. Petersburg can make a 28 m channel, and a 25 MW icebreaker of project 22600, which is being built at the Baltiysky Zavod, can make a 29 m channel. in terms of environmental efficiency.

“New oil spill collection principles have been applied on the vessel: a port is opened and oil is collected while the vessel is moving, and then oil is separated from water in special compartments using brush collectors and can be reloaded onto collection vessels”, - said Sergey Shishkin, head of the RS classification department. Such a system works even with significant sea waves.

The rest of the icebreaker's equipment, as noted in the Russian Maritime Register of Shipping, also represents the most modern models that meet current and future requirements for safety, environmental and energy efficiency, and ergonomics. It is not for nothing that the Baltika is called a multifunctional vessel - it is capable of performing several tasks at once: carrying out icebreaking operations in ports and port areas, towing ships and floating objects, escorting ships, eliminating oil and oil product spills, extinguishing fires, environmental monitoring and emergency response. rescue operations. For this, the ship has everything necessary equipment: helipad, crane with a lifting capacity of 25 tons for carrying out cargo operations, equipment for collecting oil products and lowering / lifting a work boat.

The vessel was ordered by the Federal Agency for Marine and River Transport of Russia. It's no secret that the order for the construction of "Baltika" was sent to the shipyard "Yantar". The plant signed the contract on November 9, 2011. The laying of the vessel took place on June 6, 2012. The Finnish shipyard Arctech Helsinki Shipyard Inc acted as a subcontractor of the plant. Thus, the Kaliningrad shipbuilders were engaged in the manufacture of hull blocks, and the Finns - in the formation of the hull, outfitting work and carried out tests.

Today, few can say that the project failed. Although, only shipyard workers and those specialists who were present at the tests saw it in action, and even then not in ice conditions. But it's still ahead. Next winter, all the "opponents" and "defenders" of the unusual project will be able to find out whether Baltika will cope with its "icebreaking" task or not. According to Sergei Shishkin: The real baptism of ice will take place during the next winter navigation in the waters of the Gulf of Finland, and we hope that the ship will confirm its design characteristics.”. As Igor Zubakov, project manager of R-70202, quoted by the press service of the Yantar plant, noted, the ship showed excellent running characteristics and high maneuverability during tests at sea, which means the customer will be satisfied.

The ship will be handed over to the customer in St. Petersburg. It is planned that the icebreaker will operate in the Baltic. However, among other things, the crew of the ship has yet to be prepared for work. “The Baltika is more difficult to manage than a conventional ship and requires special training. Since large shipping companies express their interest in the project, a computer-assisted training model has already been created on the basis of the Helsinki Maritime Institute for future navigators of such vessels.”, - notes the head of the RS classification department.

In the end, I would like to note that it is possible that Baltika will not be the only asymmetric icebreaker. Moreover, as the company that developed the project said, there is certainly interest in this vessel. “Now this ship is talked about at every conference on the Arctic and maritime topics. Sea trials not only confirmed expectations, but also turned out to be better. Now it is very interesting to find out how the ship will behave in the ice,”- noted in the press service of "Aker Arktic".

The innovative icebreaker Baltika is ready for transfer to the Russian rescue fleet

Recall that the launching ceremony of the Baltika took place on December 12, 2013. The 7 MW rescue vessel was built at the Yantar Baltic Shipbuilding Plant (manufacturing of hull blocks, painting), Arctech Helsinki Shipyard Inc acted as a subcontractor. (hull formation, outfitting, testing). Developer technical project(P-70202) - Aker Arctic Technology (Helsinki, Finland). The vessel is designed to perform a wide range of rescue operations both on clean water, and in ice conditions, including the elimination of emergency oil spills.

Baltika this spring will be placed at the disposal of the State Maritime Emergency and Rescue Coordination Service of the Russian Federation.

There are no analogues of such courts in the world. The fact is that Baltika has several purposes at once - rescue, cutting through channels in the ice and collecting spilled oil. The Baltika has two engines at the stern and one at the bow, they turn 360 degrees, which allows the ship to sail in almost any direction. Also, the Baltika has a helipad and a towing winch, it can work in a five-point storm, with divers and underwater vehicles, including when inspecting underwater pipelines.

According to Esko Mustamäki, Executive Director of Archtech Helsinki Shipyard, during tests at sea, the vessel confirmed its declared functionality - maneuverability, the ability to move and cut ice sideways, as well as a new type of system for collecting spilled oil. “We are extremely pleased with these properties and are confident that Baltika will help make safer shipping in the Gulf of Finland,” he stressed.

Earlier, the head of Rosmorrechflot, Alexander Davydenko, told reporters that a total of four such vessels are now being built. "Baltika" was the first launched. “It will work in the Baltic,” A. Davydenko said. - The second such vessel will be used in the Arctic, two others - on Far East and on the Black Sea. Thus, we will fully satisfy Russia's need for such courts.”

Secondly, the ability to go semi-sideways in the ice, which gives an almost twice as wide channel, 50 instead of 25 meters for a conventional icebreaker of similar dimensions. The 50-meter channel allows free passage for commercial ships. There is a second bridge for "oblique" movement.

Another replenishment took place in the regiment of the most amazing ships of the world fleet. In the spring of 2015, the Russian flag was hoisted in St. Petersburg on the multifunctional vessel Baltika, the world's first asymmetric icebreaker, or, as this latest type of vessel is also called, an oblique icebreaker.

Finnish experiment

To escort large transport vessels in ice, it is often necessary to use two icebreakers: one breaks through the channel, the second widens it, since large-capacity transport needs a wider corridor. Not very economical. The engineers of the Finnish company Aker Arctic Technology, one of the world leaders in the field of Arctic technologies, thought about solving this problem. An idea arose: why shouldn't the icebreaker move sideways in the ice in order to break through a channel of sufficient width for escorting even the largest ships? First, experiments were carried out with models in the pool, then with a conventional icebreaker, which, with the help of tugs, was forced to run into the ice with its side, not its bow. The experiments turned out to be successful, but at the same time it turned out that it was necessary to optimize the shape of the hull: the profile of one of the sides should be sharpened for working with ice. Therefore, the sides of the new icebreaker turned out to be different in shape, which made its hull asymmetrical.

The second feature of the Baltika design is the propellers. There are three of them: two are located at the stern, one is at the bow. But the main thing is that all three propellers are mounted in the form of rudder propellers (this is the common name for a device in which the propeller rotates 360 degrees, that is, the ship is controlled not by rudders, but by propellers), which can rotate 360 ​​degrees. Thanks to this, the icebreaker is able to sail not only back and forth, but also sideways or obliquely. As a result, "Baltika" with a width of 20.5 meters and a capacity of 9 MW is capable of making a 50-meter channel in the ice! For comparison: width nuclear icebreaker"Arktika" with a capacity of 49 MW - 30 meters.

Jack of all trades

The unique controllability made it possible to make the vessel multifunctional. Baltika can put out fires (including oil burning on the water), work in a cramped port area, carry out rescue operations using a 25-ton crane, serve as an airfield for helicopters, and also collect oil from the surface of the water. And the latter is done right on the go. A special hatch is provided on board - a lazport through which contaminated water enters the compartment where oil is separated using a unique patented technology. The ability to move sideways greatly speeds up the cleaning process.

The Finns did not hide the fact that they were preparing this project for Russia, which intends to engage in oil production in northern seas. And they didn't miscalculate. The Maritime Rescue Service is interested in the unique development federal agency sea ​​and river transport. The first vessel under this project, the Baltika, was manufactured jointly by the two countries. The icebreaker was laid down at the Yantar plant in Kaliningrad, and launched after completion at the Finnish shipyard Arctech Helsinki Shipyard. This shipyard is owned by the Russian United Shipbuilding Company and cooperates with VTB Bank.

In April 2015, the Baltika was tested in the ice of the Kara Sea, where it successfully overcame ice 1.5 meters thick in a straight line. A 50-meter-wide canal can be pierced in ice up to 80 cm thick. The unusual ship will take its rightful place in the list of ships that have left a significant mark on the history of the icebreaker fleet.

RIGA, 28 Dec — Sputnik. Innovation touched, it seemed, one of the most conservative areas of industry - shipbuilding. And not just shipbuilding, but the construction of icebreakers, writes the Popular Mechanics magazine.

In 1996, the Finnish company Aker Arctic began to develop a project for a fundamentally new icebreaker capable of operating bow or stern forward and, in addition, also at an angle to the diametrical surface. The tests were carried out on a conventional icebreaker, which was pulled with a lag. The results were positive, and the company developed an icebreaker with an asymmetric hull.

Others can't

When Russian government decided from the Baltic ports to Russian ones, the Agency of Maritime and River Transport of Russia became interested in the project.

The fact is that Primorsk is located much north of the Baltic ports, and in winter its water area needs to be cleared of ice. To escort large-tonnage vessels, a corridor 50 meters wide is required, a conventional icebreaker cannot cope with this task, and two pieces of equipment have to be used.

This is where the asymmetric icebreaker found its use: moving sideways, it makes a corridor of the required width.

In October 2011, the Russian Maritime and River Transport Agency, Kaliningrad and Finnish Arctech Helsinki Shipyard signed a contract, and in the spring of 2014, the world's first asymmetric icebreaker, called the Baltika, was launched.

One of the features of the vessel is three asymmetrically located rotary rudder propellers (devices in which the propeller rotates 360 degrees, that is, the ship is controlled not by the rudders, but by the propellers), one of which is located in the bow.

Due to this, the icebreaker can easily sail not only forward and backward, but also sideways and obliquely. As a result, the Baltika, which is 20.5 meters wide, makes a fifty-meter canal in the ice without outside help.

Unique and multifunctional

"Baltika" is not just an icebreaker, but a multifunctional rescue ship.

It can be used not only to break ice, but also to deal with oil spills and conduct. The left convex side is intended for ice breaking, the flat right side is adapted for collecting oil.

Moreover, oil can be collected on the go, due to the fact that a special hatch is provided on board - a lazport through which contaminated water enters the compartment where oil is separated from water using a standard built-in system of brush collectors. The oil is collected in tanks on the ship, and the purified water is pumped back to the sea.

Thanks to the rudder propellers, the Baltika has a unique maneuverability and, as a port tug, significantly outperforms traditional ships.

The ship has a helipad for evacuation, firefighting and towing equipment.

The seven-megawatt Baltika became the first in a new generation of icebreakers. In April last year, she was tested in the Kara Sea, where she easily coped with one and a half meter ice in a straight line.

Now the Finnish manufacturing company offers a 25-megawatt icebreaker designed for work in the Arctic.
