The future of the fleet of LNG tankers in Russia: a submarine nuclear tanker in the future

The lion's share of world production of tankers for transporting liquefied natural gas belongs to South Korea. It has released approximately two-thirds of all LNG ships in the worldfleet. In Russia, this branch of shipbuilding is in its infancy. But now, when the production of liquefied natural gas is beginning to develop in our country and the geography of its export is expanding, interest has also appeared in creating domestic sea vessels adapted to transport this type of fuel.



Already there are certain developments that allow us to argue that today Russia is on the verge of creating its own fleet for transporting liquefied natural gas.

Arctic LNG Tankers


On September 4 last year, at the Eastern Economic Forum, Russian companies Novatek and Sovcomflot signed a contract for the creation of a joint venture Modern Arctic Marine Transport (SMART). The task of the new enterprise is the construction and further operation of the fleet for transporting the products of the Arctic LNG-2 liquefied natural gas plant.

It is estimated that the creation of such a fleet will cost $ 5,5 billion. VEB will provide these funds under a leasing scheme. In addition, the organizers do not mind attracting outside investors into the project.

As part of the project, it is planned to create 17 Arc7 class vessels capable of sailing along the Northern Sea Route. They will run between Yamal and transshipment ports. In the west, the final destination will be in Murmansk, and in the east - in Kamchatka. There, liquefied gas will be loaded onto conventional LNG tankers. Such flights will continue uninterrupted year-round.

According to experts, the fossil fuel reserves of Yamal are approximately 13 trillion cubic meters, so any project related to the natural resources of this region is planned for a long time.

The creation of new tankers was entrusted to the Russian shipbuilding company Zvezda. Their transfer to operation is scheduled for 2023-2025.


Tankers for the Arctic LNG-2 plant will be structurally different from the ships built for Yamal-LNG, which were designed to sail both through ice and open water. In contrast, Arc7 is intended to be used only in the Arctic. Therefore, they will become narrower and more powerful in order to better pass through the ice.

Submarine Atomic LNG Tanker


On the path of LNG shipbuilding, Russia does not take the catch-up position, but goes its own way, offering innovative innovative solutions. A striking example of this is the creation of Arc7 class ships, which were mentioned above. Our country began the implementation of the project, taking into account the Russian specifics, and set about creating specialized tankers for transporting liquefied gas through the ice of the Arctic.

Another project of Russian shipbuilders is completely unique. They began work on the creation of the world's first nuclear submarine LNG tanker. This development was undertaken by the St. Petersburg Maritime Bureau of Engineering "Malachite". Work began last spring.

A gas carrier submarine is being developed for a foreign customer. It is planned to be used to transport gas produced in the northern fields along the eastern route.

Information about this appeared in the form of a company report on the corporate portal.

The last few decades, the main specialization of Malachite is the creation of nuclear submarines for the Russian Navy, which is why this organization was chosen for the development of LNG submarines.

Navy switches to gas


Recently, the degree of pollution of our planet makes it toughen environmental safety requirements in all sectors, including transport. First of all, they paid attention to road transport, as one of the most significant sources of air pollution. Now the turn has reached other modes of transport, including sea.

In particular, the International Maritime Convention has significantly tightened the requirements for the emission of harmful substances into the atmosphere.

Therefore, shipowners have to install soot traps, filters and other cleaning equipment. Because of this, many have thought about using natural gas on ships, which is one of the most environmentally friendly types of fuel.

Norway has become a pioneer in this area, using liquefied natural gas as fuel for ships for about 20 years. It was followed by Finland and Germany. Recently, the "gas" development and the Chinese. Now there are about 150 such vessels in the world, at least half of which belong to Norway.

In Russia, too, this direction begins to develop. In particular, it is known about the project for the Vyborg Shipyard to build four icebreakers for Atomflot, with a capacity of 45 MW. They plan to equip them with power plants that can operate on diesel fuel and LNG.

Tests of the LNG tanker Vladimir Rusanov:



Prospects for the establishment of LNG bunker vessels


In addition, with the advent of LNG-powered vessels, there is a need to create refueling vessels. The probability of creating bunker vessels (tankers) was considered by one of Gazprom Neft's subsidiaries.

It became known that KGNTS (Krylov State Scientific Center), on its own initiative, began to consider the possibility of LNG bunkering back in 2012. The reason for this was the information that the introduction of more stringent requirements for harmful emissions for ships became inevitable. And in 2013-2014, already in the framework of the state order, the specialists of the scientific center created a project for a small bunker for 3 thousand cubic meters. The project was even presented at several international exhibitions.

In addition, the KSCC developed a series of self-propelled and towed bunker projects and conducted model tests. At the initial stage, while the bunkering market had not yet become large, the developers proposed to produce barges with removable cargo modules so that they could be quickly converted to bunkers and vice versa.

Thus, Russia is preparing the ground to respond in a timely manner to the massive transition of ships to LNG fuel.

It seems that the Russian Federation has the opportunity to occupy its own niche in LNG shipbuilding, finding its specialization, and not trying to copy the achievements of leaders in this industry. Our country is simply forced to do this, because it is simply impossible to conquer new markets on other continents for domestic gas without our own fleet of LNG tankers.

          The gas carrier is supposed to be atomic, so the lost gas will probably be partially captured and liquefied.
          There are also solid oxide methane fuel cells, for example (but they require an oxidizing agent).

              The plant is redundant, rather a cryogenic refrigerator unit is needed (T = -160 ° C is needed). But in any case, low-temperature refrigerators will be needed, since liquid gas must be cooled so that the tanks do not break; but ICE - exactly redundant.

          Well, yes, an ordinary projection, no more. This topic has probably been discussed since the time of the picture that you presented.
          If we seriously discuss this project, the underwater tanker should be much larger in volume, mass than surface. Do not forget from water tanks when diving. And they should be just huge, try to immerse such a bulk. To collect water in tanks for fuel ... yes, such fines for pollution will be rolled out.

            The gas is well separated from the water (which will be pumped into the sea when it emerges) in a vacuum installation. Therefore, you can safely fill the gas tanks with water and go to great depths where gas evaporation is hindered by high pressure and thereby saves the cost of cooling it. But normal ascent will be a very, very quick process - in order to clean the evacuated water by evacuation, you will have to rise from the depths for at least a few days, cutting circles like an airplane in a near-airport airspace.

          Somewhere you made a mistake in the calculations. The volume of 3105 cubic meters is comparable to just one, but also the largest, second (residential) compartment of the 971 project, which I served in my time. If you take a pipe (cylinder) with a diameter of 23 meters and a height of 172 meters (as you indicated in the example), then the numbers are completely different:
          formula for calculating the volume of the cylinder -



          i.e. multiply the area of ​​the base by height.

          In our case, we get 3,14x11,5x11,5x172 = 71425 cubes

            The difference between underwater and surface displacement is approximately = buoyancy margin. It turns out that it takes in the tank 48000-25000 (not taking into account the characteristics of the tanks and the approximate figures given) 23000 water. Then it will sink.

      Wärtsilä 12-cylinder LNG engine

      From this


      the ship for the transport of 74 cubic meters of gas "releases" N-BOG about 000 cubic meters per day.
      N-BOG is the LNG vapor, or Natural Boil Off Gas, and makes up about 0,1% to 0,15% per day of the amount of cargo
      The expansion coefficient for gas, from the liquid phase to the gaseous, is 600: 1, that is, 74 cubic meters equals 44 cubic meters of gas.
      The net calorific value (LCV) of the vaporized gas varies with the nitrogen content that is present in N-BOG. The nitrogen content may be higher than 30% of the volume of boiled-off gas at the beginning of the voyage, because nitrogen has a lower boiling point than methane. But we already know that the lighter elements are the first to boil.
      Therefore, the LCV figure is as follows - 28 MJ / m3.

      Next, we have energies of 44 x 400 = 28 MJ per day.

          Well, of course, they are above-water, but of an increased ice class - they’re also not cheap .. of course, but they’re not ... But here we are not afraid of weather and hummocks ...

      not quite sure what HBO means. I have a scrubber on my car; well, for an exhaust gas, it reduces the nitrogen content, which is what new car makers are fighting right now, since sulfur has almost been removed from fuel. of the remaining hundred comments, people are far from what the conversation is about. and STX and Hyundai put man burmstr two-stroke long-stroke on LVJ LVZh which worked both on heavy and heavy duty and on cargo and this topic for about 15 years. once again - the ship is being laid, the buyer has the option of which engine to install which cargo - everything from the price tag ...

    I read the comments, some well-wishers and experts in the field of shipbuilding belay
    And recently they were outstanding virologists, pulmonologists! what

      So the students are sitting at home. So the expert community has replenished with new specialists of a wide profile.

    It would be interesting to learn from knowledgeable people about the construction of tankers at the Zvezda plant in Bolshoy Kamen. There is practically no information about this on the internet. Isn't Zvezda similar to the Vostochny cosmodrome? -Fixing and cutting ... It was written on the Internet that the construction was carried out with the help of Korean firms.
    Moreover, OURS DO ONLY THE MIDDLE PART. And the stern part with the superstructure with the machine and mechanisms is brought in the dock from Korea ??? For those who are not very familiar with shipbuilding, I will say that the middle part is a fairly simple structure in the form of iron containers, albeit large, and the most complex and technologically advanced is the stern part with mechanisms. Is the full cycle of shipbuilding done at Zvezda or ... just welders weld metal structures !? It took a long time to build Zvezda ... In addition, information about the conclusion of a contract for the construction of a giant nuclear icebreaker at Zvezda slipped through the press.

    A little clarification. The Arctic LNG-2 plant will be located not on the Yamal Peninsula, but on the neighboring Gydan Peninsula. Regarding the village of Sabetta, it is across the lip.

    The depths in the Gulf of Ob are very small. The sea channel, which is dug 16 meters deep and 295 meters wide. Beyond the Sea Canal, depths less than 12 meters. And what kind of submarine tanker is it? For ordinary gas carriers, the length of which is 300 meters, and the width of 50 meters of passage of the Sea Canal always presents certain difficulties. Desires and opportunities are two different things.

    Another couch strategist hatched. Such a gas tanker costs almost 300 million, and not rubles. How much will nuclear, and even underwater? And the infrastructure for him? And in general, there is nothing special to be proud of:

    Gas tanker Vladimir Rusanov was built for Mitsui OSK Lines (MOL) and China COSCO Shipping. It is also the first of three Arc 7 ice-class LNG tankers that the companies are jointly building for NOVATEK's Arctic project. Gas tanker Vladimir Rusanov IMO: 9750701, flag of Hong Kong (China), was built in December 2017. Shipbuilder: Daewoo Shipbuilding & Marine Engineering, South Korea. Manager / Owner: DY Maritime Ltd.

    Well, it’s also worthwhile to raise the youth technology magazines for the 1970s:

    It is planned to create 17 Arc7 class vessels capable of sailing along the Northern Sea Route. They will run between Yamal and transshipment ports.

    Maybe it would be better to build LNG plants in Murmansk and Kamchatka, and throw gas pipelines to them? And the submarine fleet is not needed?

    Everything is not simple, but very simple - the specific gravity of LNG is 0,45 tons / cubic meter, therefore the specific underwater gas carrier should be 0,55 tons / cubic meter.

    The surface gas carrier "Vladimir Rusanov" has a total displacement of 128 thousand tons with a tank volume of 171 thousand cubic meters. Those. An underwater gas carrier, in order to submerge under water, must have a reactor installation, a strong body and ballast (for example, in the form of cast iron) with an additional weight of 43 thousand tons. Therefore, a nuclear tanker with direct cargo delivery will be comparable in profitability to a surface icebreaker analogue with cargo transshipment only when transporting liquid products of natural gas processing with a specific gravity of 0,8 - 0,9 t / mXNUMX.

    The draft of the Vladimir Rusanov is 12 meters, the draft of the underwater tanker on the surface will be about 15 meters, which is not critical for the approach to the industrial sites for processing natural gas on the Yamal Peninsula through the sea channel. The further route of the underwater tanker in a submerged position to the Bering Strait or to the Scandinavian Peninsula will run along the shortest distance with depths of several hundred meters.

    I hope it will not reach the construction of an underwater nuclear gas carrier. And all this creative energy will be able to be directed into a "peaceful" channel. For the creation of military submarines.

      Maybe better first underwater BDK? The project was developed in detail, it was not built then (according to words) due to the fact that the shipyards in Nikolaev were engaged in aircraft-carrying cruisers ..
