Icebreaker "Vladivostok": technical characteristics, photo. Tests of the icebreaker "Vladivostok"

In the fourth quarter of 2012, the icebreaker "Vladivostok" of Project 21900 M was built at the Vyborg Shipyard. The vessel is one of the most powerful in its class. 21900 M is an upgraded version of the previously launched 21900. Vladivostok is the first icebreaker of the three, created by the project 21900 M, and the third in the 21900 series. In 2006, Moscow and St. Petersburg came down on the water. Both ships were taken over by Rosmorport.

The picture shows the ice breaker "Moscow" - the flagship of the 21900 series. The greater number of crew members, the possibility of taking on board special personnel, the transfer of the helipad to the bow of the vessel, the installation of a more powerful crane, the expanded cargo deck can be attributed to the differences of the modernized project. In October 2015, the icebreaker Vladivostok, the first of three new type ships, was handed over to the customer, the Rosmorport Company.

Stages of creation

Construction of two of the three planned icebreakers of the 21900 M series began in 2012. The deadline for both was set at the beginning of the winter navigation of 2015-16. The third should be delivered at the end of 2016. The vessels were called Vladivostok and Murmansk. The first was built at a plant in Vyborg (Leningrad region), the second - at a plant in Helsinki (Finland). According to official data, as of February 2016, the Vladivostok icebreaker operates in the relatively new oil port of Primorsk located in the Gulf of Finland in the Baltic Sea. Since both ships were built in parallel, they received the same blocks and even the test dates, briefly go through the dates of the creation of one of them. Namely, the flagship of the series, which is the icebreaker "Vladivostok", a photo of which is presented below.

In this perspective, a helicopter pad located on the bow of the vessel is clearly visible - a distinctive feature of the "M" project.

So, the chronology of construction:

• In October 2012 construction began.

• August 5, 2013 - the ceremony of the formation of the corps.

• April 29 next year, the future icebreaker is launched. Go to setting up the equipment.

• On November 18 the same year (2014) - the installation of screw-steering columns.

• December 2014 - April 2015 - mooring trials.

• August 12 - delivery of a towing winch, a windlass and mooring winches by the Finnish colleagues.

• September 12, 2015, sea trials of the icebreaker "Vladivostok" start, which lasted until October 5.

• October 9, 2015 in St. Petersburg, a solemn ceremony of signing the act of surrender-receiving the vessel.

Design Features

One of the interesting features of the project 21900, which became a simpler implementation of the project 21180, was the helm-steering column. The icebreakers of this project practically do not have the concept of "reverse gear". Thanks to the system of additional shafts, Vladivostok can move in any direction with the same speed, at least with the nose, at least with the stern, or with the side. In the project 21180 there are no shafts - there the propellers are planted directly on the axis of the electric motor, which is actually outside the icebreaker's body, whereas at Vladivostok it is inside.

Just like the nuclear icebreaker, Vladivostok has a fuel reserve that allows it to stay in the sea for up to 40 days, modern navigation equipment that makes it possible to work both in the clear sea and in difficult arctic conditions, but it is not considered a class Nuclear icebreakers.

Atlant

For "Vladivostok" and subsequent orders, Vyborg shipbuilders built a special self-loading barge "Atlant" for 10 months. The principle of its operation differs little from the usual floating dock, except that "Atlant" is busy on construction, and not current repairs. The capacity of the barge makes it possible to build ships up to 150 meters long and up to 30 meters wide (Vladivostok length ~ 120 meters, width 27 meters).

During its construction, special types of steel were used, thanks to which the barge is able to work in ice. Work inside it can be conducted 24 hours a day and 365 days a year. Therefore, the icebreaker "Vladivostok" was built in just 2 years. In addition to launching and building ships, the barge is also designed to receive cargo outside the shipyard.

Raising the flag

A major test of the ship is the arrival in St. Petersburg and mooring at the embankment of Lieutenant Schmidt. Within three days (from September 22 to September 25) during several excursions anyone could get there and inspect the new icebreaker "Vladivostok". The flagging ceremony on the ship was one of the planned events of the exhibition, and on September 23 the Russian tricolor soared above the icebreaker.

As the governor of the region said at a press conference, this is a real holiday for the whole country. The event was attended by representatives of local authorities, Deputy Minister of Transport, representatives of the Directorate of Black, Caspian and Azov Seas ports, a representative of the administration of the ports of the Baltic Sea.

Testing

In addition to "visiting" the exhibition, almost a month the icebreaker was in the open sea. The maneuverability of the vessel, the performance of individual units and all systems as a whole were checked. The sea trials for ships of this class consist of two parts. Directly running - in the clear sea, and ice testing - in the zones as close as possible to the places of future work of the vessel. This allows you to identify in time all the shortcomings. The second ice tests are scheduled for April 2016. Unlike the work in the port, this time the plans to call at the port of Murmansk, and then "Vladivostok" will go to the Arctic to test icebreakability.

As reported in official sources, the icebreaker will go to the Arctic more than once. The company he should make "Murmansk" - the second ship built according to the project 21900 M in Helsinki. After the completion of all the tests, both ships should return to St. Petersburg.

Vessel characteristics

Now it's time to take a closer look at the icebreaker "Vladivostok": technical characteristics, displacement, engine power and other parameters. For a better understanding, let's compare icebreakers "Moscow" (21900) and "Vladivostok" (21900 M). So, the number of crew on the "Moscow" is 26 people, on the new ship - 37. In addition to the main tasks, the new icebreaker can be used as a scientific research vessel, and take on board 25 more scientists. The length is 114 and 119 meters, respectively. The displacement is 14,000 and 14,400 tons. The width is 28 and 27 meters. We will not compare the deck characteristics, just point out that the new icebreaker is stretched from side to side, and beneath the helicopter pad that has moved to Vladivostok's nose, the useful space of the deck also continues. The common for both projects is one - both of them belong to the class of diesel-electric vessels, in this case they are linear diesel-electric icebreakers.

Proceeding from this, the sphere of use of vessels of the new project is wide enough. In addition to laying a path with a continuous speed of up to 2 km / h, they can work as research, industrial and supply vessels.

From the inside

In addition to the main technical characteristics, it can be separately mentioned that the developers revised not only the running characteristics. A new design was made for the icebreakers of the new project. Every detail meets the conditions of economy, durability, fire safety. As noted by representatives of many St. Petersburg universities (whose graduates may fall honor to join the team of new ships) - for the first time it can be called a "real sea home". We note that the plans of the corporation, which includes the Vyborg plant, the creation of special factories for the production of practical and good ship furniture. After all, the main thing in the business is not metal, construction, machines, but people managing all this. And if we consider that the sphere of application of new icebreakers is not limited to working in the water areas of ports, this issue is of paramount importance.

Conclusion

The icebreaker Vladivostok started its working life in the winter navigation 2015-2016 in the Russian sea oil port of Primorsk. In April 2016, he was paired with Murmansk, the second icebreaker of the 21900 M project, going on ice tests to the Arctic. As they say to all ships - 7 feet under the keel and successful work both in ice conditions and in clean water
