Russian experts have learned to move the icebergs in the Arctic seas
MURMANSK, October 10 -. RIA Novosti Participants of the expedition "Rosneft" on the icebreaker "Kapitan Dranitsin" with the scientific support of the "Akademik Tryoshnikov" vessel for the first time in Russian history held in the Kara Sea towing icebergs experiments, many of which are in the tens of times the size of the ice-breaker, told reporters the participants of a unique campaign in Murmansk.
Drifting icebergs pose a real danger to navigation and management of industrial activities on the Arctic shelf.Russian scientists have developed a unique technology that allows to change the trajectory of the icebergs drift. The expedition set off from Murmansk in mid-September. Its participants managed to conduct 18 experiments in tow, and the weight of the largest iceberg has exceeded one million tonnes.

The task - to tame the icebergs
The challenge to manage icebergs in the Arctic seas seems ambitious and hardly - every schoolboy knows that the surface of the water rises only about 10% of the ice blocks, the hidden underwater portion can be of any size and shape. To cope with this problem come from employees "Arctic and Antarctic Research Institute".
"The experience of using the icebreaker to tow icebergs -. Russia's first Before that there were attempts to carry out such experiments, they have not been targeted - in 2006" Mikhail Somov "tried, but unsuccessfully - properly this experiment was unprepared, lucky they were not accompanied" - said the deputy head of the expedition senior researcher Evgeny Makarov Institute.
Arctic Institute on the instructions of "Rosneft" Experts have proved the possibility of such experiments. It was planned that the participants of the expedition will conduct 12 experiments, but they have managed to surpass the plan. "Run 18 experiments on the towing of icebergs, of which only two can be considered unsuccessful rest were good We were able to move, move, change direction nine icebergs..", - Said the head of the expedition, "Iceberg-summer 2016" Alexei Chernov.

Blocks of ice with unknown parameters
About cunning icebergs known not only because of the "Titanic". Floating ice blocks can carry a drilling platform to cause harm to the courts, to nullify the efforts to the offshore industry. The only way to avoid a lot of problems - to move the iceberg, or drag it to the side, but it's just only in words.
"Iceberg is a block of ice with unknown parameters. We only see the tip. At the bottom can be very different keel ... He can turn, begin to drift to the other side, can do cases, if there is still a floating structure, and the iceberg starts to drift on it" - says the deputy head of the expedition.
Work to tow the iceberg, according to experts, require a jeweler's precision - to predict how to behave in a block of ice, it is not always possible. The task is complicated and weather conditions of the high seas - the excitement, wind, poor visibility.

Iceberg weighing a million tons
"Iceberg stood icebreaker came, we did a circle etched rope, then from the deck to catch the free end, raised, secured, stretched and began to haul in the right direction. The biggest (iceberg) which we are" caught ", was more than 150 meters in length , the same width and more than 100 in depth - in total more than a million tons was, "- says the head of the expedition.
"Displacement of the vessel - 15 thousand tons of icebergs with a similar displacement of almost no - they are more than 100 thousand tons, at times greater than the maximum iceberg was more than a million tons -. Had to take care not to break the tow ropes," - says chief mate "Dranitsyna" Albert Mospan.
icebreaker team also was pleased with the results of the work. According to the participants of the expedition, it is Captain has to make difficult decisions and to take responsibility. "We appreciate the work perfectly, this experiment was first conducted no damage to the ship and the equipment is not applied You can take this experiment as the basis for further work..", - Says Mospan.

Moving icebergs can be faster
The main results of the expedition, according to its members - the Russian specialists were able to prove that the work on the movement of icebergs - on forces to man, and the experiments open up new opportunities for those who work in the Arctic seas.
"The greatest joy - those technical solutions that we adopted before the start of the experiment - they all survived, everything was possible to say with certainty that if such a problem in practice, on the battlefield will be delivered -. It is possible to solve this problem", - with welcomes the head of the expedition.
Set records for high-speed movement of the ice blocks in the open sea until no one is going. According to head of the expedition, in the future it is possible to carry six to eight tows per day subject to availability of a sufficient number of specialists and equipment.
