Asymmetrical icebreaker Baltika accepted into service Russian fleet(PHOTO, VIDEO)
On February 20, 2015, a ceremony to raise the Russian flag took place on, in official terms, the multifunctional diesel-electric rescue vessel Baltika. How is Baltika unique? Firstly, the asymmetrical contour of the body.
Secondly, the ability to sail 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 canal allows commercial vessels to pass freely. For oblique movement there is a second bridge.
Project R-70202 innovative icebreaker to combat emergency oil spills and rescue operations was developed by the Finnish company Aker Arctic Technology. The icebreaker was created in two stages. They were laid down in June 2012 at the Kaliningrad Yantar, 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 eliminating emergency oil spills, extinguishing fires, and environmental monitoring. It is capable of moving in flat ice 1 m thick. The length of the vessel is 76.4 m, width - 20.5 m, draft - 6.3 m, power of three diesel generators - 7.5 MW, speed - 14 knots, speed at 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 construction of the vessel had just begun, some spoke of it with a bit of irony, mainly due to the fact that the term asymmetrical was often confused with the word “crooked” or “oblique,” which is not very close to the truth. And in fact, this asymmetry itself became business card project.
“A competition has been announced for the skewed captain”
(commentary to the Newsland news)
“And it will always be driven by a “crooked” crew”
(comments to the news “Military Industrial Complex News”)
“If the ship looks like a freak, then it will be operated like a freak! The lesson of “popovoks” did not go well (or maybe modern Internet designers have never heard anything about them).”
(commentary to the news "Korabel.ru")
They gradually stopped making fun of the design of the icebreaker when photographs and videos appeared on the Internet, in which one can clearly see that the ship is not just another “myth”, but the very real reality. But shipbuilders and simply interested people found another reason to lament and make fun of the domestic shipbuilding industry. However, this is more likely not dissatisfaction and aggression, but an ordinary statement of fact with a slight dose of sadness and self-irony - they say, although the Baltika is ours, it was only built by the Finns. And no excuses regarding the supply of body parts with domestic enterprises and the excessive workload of the shipyards of our country, those advocating Russian shipbuilding cannot be pacified.
Thus, at the “Russian Shipbuilding” conference, which was held in St. Petersburg in April 2014, the head of TsNIIMF CJSC Sergei Buyanov noted in his welcoming speech 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 icebreaking vessel is almost ready to work “at one hundred percent.” And those who were present at the sea trials were personally able to see that the slightly non-standard approach to design still became a kind of breakthrough.
And although the project has only now received its material embodiment, as we were told by Aker Arktic, which is the developer of the Baltika project, the idea of an asymmetrical icebreaker was born in the late 90s, when the requirements for icebreaker support for the Baltic Sea fleet were analyzed.
By the end of 1996, the idea of creating a lag-moving icebreaker was developed, and in 1997 the first model tests of the ARC 100 project took place. “Later, a decision was made to build an oil terminal in Primorsk. That’s when the idea came up to use the vessel to combat oil spills.”, - the company reported.
Further work on the development of the project continued in cooperation with the Maritime Administration of Finland, the Finnish Environmental Institute and ABB, with partial financing of the work by the Technology Fund of Finland. As a result, the updated project was presented to the administrations of Finland and Russia in 2003. The Russian Ministry of Transport placed an order for the construction of the vessel when the contract was signed in 2011.
In general, a ship similar to the Baltika could have been built even earlier. Sales Director Arto Uuskallio spoke about this when “Korabel” visited “Aker Arktic” (see article “Shipbuilding in Finland. Part 2: “Aker Arctic” - “It is difficult to prove the advantages of an innovative approach”): “We had the opportunity to implement this idea earlier, but the Customer then last moment preferred the traditional concept of the vessel. This is an advanced development, and conservative thinking is professed in shipbuilding. It is difficult to prove the benefits of an innovative approach".
“In general, the emergence of such a project was a kind of response to the increase in the number of tanker traffic in the Gulf of Finland”,” notes Aker Arktic. The asymmetrical icebreaker is a continuation of the tradition of using the method of moving stern first in ice on ships. In practice, the Baltika, by moving forward at an angle to the center plane, makes a channel 50 meters wide, replaces the work of two icebreakers.
Aker Arktic has patented the idea of an asymmetrical hull. There are no analogues in the world, the project developers note. And Baltika is the first ship built according to the ARC 100 project. “The project has now been expanded to a strengthened version designed for more severe operating conditions in the Arctic”, - the company reported.

“The secret to the uniqueness of creating a vessel concept lies in an integrated approach to solving problems. This is a multifunctional icebreaking vessel. It is ideal for year-round emergency duty for oil spill response, escort operations, emergency towing, firefighting and monitoring. environment» , noted the Finnish company.
The vessel is equipped with a diesel-electric installation with three azimuth propellers - one of the devices is located in the bow, the second in the stern and the third on the side of the hull. This solution provides effective work of the vessel when moving bow, stern and lag. Also, Baltika’s operation is supported by thrusters with a total power of 7.5 MW. The salvage vessel has a double bottom, a continuous main deck and tween deck, and a forecastle. Superstructure with residential and office premises located in the bow of the Baltika.
The vessel is capable of moving in flat ice 1 m thick both bow and stern forward and at an angle, laying a channel up to 50 m wide in flat ice 60 cm thick. For comparison, according to some data, the diesel-electric icebreakers "Moscow" and "St. -Petersburg can make a channel 28 m, and the 25 MW icebreaker Project 22600, being built at the Baltic Shipyard, can make a 29 m channel. It is worth noting that the Baltika engines can run on fuel with low sulfur content, and this is especially important with from an environmental efficiency point of view.
“The ship uses new principles for collecting oil spills: the port opens and collects oil while the ship is moving, and then in special compartments, using brush collectors, the oil is separated from the water and can be reloaded onto assembly vessels.”, - said Sergey Shishkin, head of the RS classification department. Such a system works even with significant sea waves.
The rest of the equipment of the icebreaker, 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’s not for nothing that the Baltika is called a multifunctional vessel - it is capable of performing several tasks at once: conducting icebreaking operations in ports and port waters, towing ships and floating objects, piloting ships, cleaning up emergency oil and oil product spills, extinguishing fires, environmental monitoring and emergency response. rescue operations. The ship has everything for this necessary equipment: helipad, crane with a lifting capacity of 25 tons for cargo operations, equipment for collecting oil products and lowering/raising a work boat.
The customer of the vessel was the Federal Agency for Maritime and River Transport of Russia. It's no secret that the order for the construction of Baltika was sent to the Yantar Shipyard. The plant signed a contract on November 9, 2011. The keel of the vessel took place on June 6, 2012. The Finnish shipyard Arctech Helsinki Shipyard Inc. acted as a subcontractor of the plant. Thus, Kaliningrad shipbuilders were engaged in the manufacture of hull blocks, and the Finns were engaged in the formation of the hull, outfitting work and carried out tests.
Today, few can say that the project was a failure. 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 this is still ahead. Next winter, all “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 Gulf of Finland, and we hope that the vessel will confirm its design characteristics.”. As noted by the head of the R-70202 project, Igor Zubakov, who was quoted by the press service of the Yantar plant, during tests at sea the vessel showed excellent performance characteristics and high maneuverability, which means the customer will be satisfied.
The vessel 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 ship’s crew still needs to be prepared for work. "Baltika" is more difficult to navigate than a regular ship and requires special training. Since large shipping companies have expressed interest in the project, a computer training model has already been created at the Helsinki Maritime Institute for future navigators of such ships.”, - notes the head of the RS classification department.
In the end, I would like to note that perhaps the Baltika will not be the only asymmetric icebreaker. Moreover, as they said in the company that developed the project, there is certainly interest in this vessel. “Now this ship is talked about at every conference on Arctic and maritime topics. Sea trials not only confirmed expectations, but also turned out to be better. Now it’s very interesting to find out how the ship will behave in ice,”- noted the press service of Aker Arktic.
The innovative icebreaker ship “Baltika” is ready for transfer to the Russian rescue fleetLet us remind you that the launching ceremony of the Baltika took place on December 12, 2013. The 7 MW salvage vessel was built at the Yantar Baltic Shipyard OJSC (production of hull blocks, painting), Arctech Helsinki Shipyard Inc. acted as a subcontractor. (hull formation, outfitting work, testing). Developer technical project(P-70202) – Aker Arctic Technology (Helsinki, Finland). The vessel is designed to perform a wide range of rescue operations, both clean water, and in ice conditions, including the elimination of emergency oil spills.
“Baltika” will go to the disposal of the State Maritime Emergency and Rescue Coordination Service of the Russian Federation this spring.
There are no analogues of such vessels in the world. The fact is that the Baltika has several purposes at once - rescue, cutting channels in the ice and collecting spilled oil. The Baltika has two engines in the stern and one at the bow; they rotate 360 degrees, allowing the ship to sail in almost any direction. The Baltika also has a helipad and a towing winch; it can work in force five storms, with divers and underwater vehicles, including when inspecting underwater pipelines.
According to Archtech Helsinki Shipyard executive director Esko Mustamäki, 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 shipping in the Gulf of Finland,” he emphasized.

Earlier, the head of Rosmorrechflot, Alexander Davydenko, told reporters that a total of four such vessels are currently being built. “Baltika” was the first to be launched. “It will work in the Baltic,” said A. Davydenko. – The second such vessel will be used in the Arctic, two others will be used in Far East and on the Black Sea. Thus, we will fully satisfy Russia’s need for such vessels.”
Secondly, the ability to sail 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 canal allows commercial vessels to pass freely. For oblique movement there is a second bridge.

Sea trials not only confirmed expectations, but also turned out to be better. Now it’s very interesting to find out how the ship will behave in ice,”- noted the press service of Aker Arktic.
The regiment of the most amazing ships of the world fleet has received another replenishment. In the spring of 2015, in St. Petersburg, the Russian flag was raised on the multifunctional vessel Baltika, the world’s first asymmetrical icebreaker, or, as this newest type of vessel is also called, an oblique icebreaker.
Finnish experiment
To guide large transport ships through ice, it is often necessary to use two icebreakers: one breaks through the channel, the second widens it, since large-tonnage 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 through the ice in order to carve out a channel wide enough to accommodate 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, and not its bow. The experiments turned out to be successful, but at the same time it became clear 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 design feature of the Baltika is the propellers. There are three of them: two are located at the stern, one at the bow. But the main thing is that all three propellers are mounted in the form of rudder columns (this is the common name for a device in which the propeller rotates 360 degrees, that is, the ship is controlled not by the rudders, but by the 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, the Baltika, with a width of 20.5 meters and a power 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.
Handyman
Unique controllability made it possible to make the vessel multifunctional. The Baltika can extinguish fires (including oil burning on the water), work in tight port waters, 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. Moreover, the latter is done right on the go. There is a special hatch on board - a lapport, through which contaminated water enters the compartment where oil is separated using a unique patented technology. The ability to move sideways significantly 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 were not mistaken in their calculations. The Marine Rescue Service became interested in the unique development Federal agency sea and river transport. The first ship 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 Arctech Helsinki Shipyard. This shipyard belongs to the Russian United Shipbuilding Company and cooperates with VTB Bank.
In April 2015, Baltika was tested in the ice of the Kara Sea, where it successfully crossed ice 1.5 meters thick in a straight line. The ship is capable of making a channel 50 meters wide in ice up to 80 cm thick. The unusual ship will take its rightful place in the list of ships that have left a noticeable mark in the history of the icebreaker fleet.
The Fab Five
Five revolutionary projects that became a milestone in the development of icebreaking shipbuilding.
RIGA, December 28 – Sputnik. Innovation seemed to affect one of the most conservative areas of industry - shipbuilding. And not just shipbuilding, but the construction of icebreakers, writes the magazine Popular Mechanics.
In 1996, the Finnish company Aker Arctic began to develop a project for a fundamentally new icebreaker, capable of working bow or stern forward and, in addition, also at an angle to the diametral surface. The tests were carried out on a conventional icebreaker, which was pulled by a log. The results were positive, and the company developed an icebreaker with an asymmetrical hull.
Others can't do that
When Russian government decided from the Baltic ports to Russian ones, the Russian Maritime and River Transport Agency became interested in the project.
The fact is that Primorsk is located significantly north of the Baltic ports, and in winter its water area needs to be cleared of ice. To navigate large-capacity 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 asymmetrical icebreaker found 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 Baltika, was launched.
One of the features of the vessel is three asymmetrically located rotary rudder columns (devices in which the propeller rotates 360 degrees, that is, the ship is controlled not by rudders, but by 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, whose width is 20.5 m, makes a fifty-meter channel in the ice without outside help.
Unique and multifunctional
"Baltika" is not just an icebreaker, but a multifunctional rescue vessel.
It can be used not only to break ice, but also to combat oil spills and carry out. The left convex side is designed to break ice, the flat right one is designed to collect oil.
Moreover, oil can be collected directly on the move, due to the fact that there is a special hatch on board - a lapport, through which contaminated water enters the compartment where oil is separated from water using a standard built-in brush collector system. The oil is collected in tanks on the ship, and the purified water is pumped back to the sea.Thanks to its rudder propellers, the Baltika has unique maneuverability and, as a port tug, is significantly superior to traditional vessels.
The ship has a helipad for evacuation operations, equipment for firefighting and towing.
The seven-megawatt Baltika became the first in a new generation of icebreakers. In April last year, it was tested in the Kara Sea, where it easily coped with one and a half meter ice in a straight line.
Now the Finnish manufacturing company is offering a 25-megawatt icebreaker designed for work in the Arctic.
