Diesel icebreaker Ob launched for the Yamal-LNG project in Vyborg

In Vyborg, the first non-nuclear icebreaker of Rosatomflot Ob was launched, commissioned by Atomflot FSUE of Rosatom State Corporation. The construction is carried out by PJSC "Vyborg Shipbuilding Plant", the Rosatomflot communications department reported.

This diesel port icebreaker "Ob" was laid 27 September 2016, the project "Yamal LNG". The length of the vessel is 89,2 m, width - 21,9 m, draft - 7,5 m. The purpose of this type of icebreakers - work in ports and coastal areas. The greatest
The icebreaker performance is achieved when the ice thickness is no more than 1,5 meter at the speed of the 2 node, and can also reach the speed of the 4 node in broken ice with a thickness of up to 5 meters. Four independent azimuthal propulsive installations with an electric drive of a traction type are installed on the icebreaker. They are located in pairs in the bow and stern parts of the icebreaker, which allows the vessel to move in the ice both bow and stern. The power of each azipod is 2,5 MW. The crew of the icebreaker 19 man.

After completion and completion of all the required tests, this icebreaker will go to the Yamal Peninsula to escort LNG tankers and service the water area of ​​the Sabetta port for the Yamal LNG project.

7 feet under the keel ......... was only ours

Four independent azimuthal propulsion systems with an electric traction-type drive are installed on the icebreaker, located in pairs in the fore and aft parts of the icebreaker, which allows the vessel to move in the ice both fore and aft.

Baltica (IMO No. 9649237) was built by Arctech Helsinki Shipyard (Helsinki, Finland) in cooperation with JSC Yantar Shipyard (Kaliningrad, Russia) on the basis of the Aker Arctic, Aker ARC 100 inclined icebreaker. The Baltic Sea is driven by three azimuth engines 2,5, XNUMX MW Steerprop, two in the stern and one in the bow. Dynamic positioning system, which also includes an oblique icebreaking mode,

Sanya, hi to that bukhchu, so that the icebreakers themselves build!

[san4es]

Healthy Andrei ... Well, Ob already with 4 azipods - progress

[Vladimir 5]

They managed to mold a platform on the nose in the Baltika branch, and so on primitive, amateur. During the course of the vessel and the wind, the flight is difficult to enter and land, and probably more than once a helicopter, during the course of the vessel, will drop onto the captain’s bridge ...

They managed to mold a blind spot on the “Baltika” branch

...This is normal. There is no other place.

During the course of the ship and the wind, the flight is difficult to enter and land, and probably more than once a helicopter, during the course of the ship, will drop onto the captain’s bridge ...

... It already depends on the pilot and technology ... There are, and out of the blue problems:

In the winter, Baltika on the Gulf of Ob works in the area of ​​Cape Kamenny. Serves the oil loading terminal "GPN".

Thanks for the info

A couple of containers with Club-K missiles and a Tor-m2m air defense module will look very good on the icebreaker’s deck

Why isn’t it right that Poplar is in the armata hold on deck?

[Vladimir 5]

This may be outlined in a special period, and there’s nothing to carry the unnecessary ballast. For the passage of ice over 100 cm, it is not better to cut the ice in the direction of the portable circular saw on the console, and at least a third or half of the thickness, the ice will be lomatically neat, without jerking back and forth ... And cut it in 2 to 3 cuts in width, so In general, the correct channel will be arranged. Speeds are then 2-3 miles in the normal course, doubled undercut ....

Where does such a competent inventor come from?

[Servisinzhener]

Everything has already been invented. In the case of a more complex ice situation, he is likely to move stern forward. On the National Gographic channel, there was a program about the development of icebreakers, including the tanker Timofey Guzhenko (he is an ice class). And when the ice situation worsened, we had to turn around and move forward aft, because while the screws help break the ice.

[petrol cutter]

Are the screws designed for breaking ice? A question asked me. Break your blades, you’ll remain without a move. What will you do? What does the channel think about this?

[Servisinzhener]

They say that they are designed, even showed a test pool with ice where models of icebreakers are tested. But they didn’t seem to talk about how thick the ice was. Here is this program about icebreakers: https://rutube.ru/video/77506f0019b519392e087a378

Che is not atomic? Nafig this fuel.

[Chicha squad]

Still need to move the retirement age? Or will you bring money to the state?

[Vladimir 5]

The government has funded enough state money over the hill, their main concern is that the ruble doesn’t strengthen, people don’t get better, when the steering wheel is on the baseboard, then less oil dollars are spent on the budget, the United States steals more or buys it ...

[Heterocapsa]

I’ll bring it up.

Write correctly !!!

[Vard]

Whoever doesn’t profit from gas ... Now, shipbuilders also ... By and large, at current gas prices ... It will not be possible to recoup investments .... So the whole banquet is at our expense ...

10 MW of power at Azipods is approximately 13,600 hp. - It looks not enough for working in ice 1,5 m. Moreover, Sabetta - there is desalinated ice. In continuous solidified even sea ice of 1,5 m. With such power it will have to be hard. Azipods, with all their positive qualities, such as increased maneuverability of the vessel, the ability to work stern ahead, also have a drawback - insufficient reliability and very expensive maintenance. They fail, as a rule, unexpectedly and immediately. Yesterday I worked - today I’m not working, I need repairs. Icebreakers on classic shaft lines have worse performance "power - ice thickness", but much more reliable.
