Ministry of Transport and Rosprirodnadzor are thinking about how to raise the sunken tankers from the bottom of the Kerch Strait

Scientists, together with specialists from the Ministry of Transport, are developing a method for raising parts of the two Volgoneft tankers from the bottom of the Kerch Strait, which crashed in mid-December due to difficult weather conditions. During this time, the vessels of the FGBU "Morspassluzhba" examined 809.8 sq. km of water area, cleaned 35.5 thousand sq. m. Specialists continue to conduct round-the-clock environmental monitoring of the sea surface.

The volume of oil products that entered the sea is already about 2.4 thousand tons, and when lifting to the surface, the main thing is to prevent new leaks. According to the press service of the Ministry of Transport, despite the storm and low visibility under water, divers of the Morspassluzhba completed an inspection of the sunken fragments of tankers at a depth of 17-23 meters. They seal possible places of damage to tanks.

The complexity of the task is that the disaster in the Kerch Strait is practically became the first in the world, where M100 fuel oil spill occurred: this fuel is not amenable to traditional cleaning methods.

M100 fuel oil freezes at a temperature of +25℃, has almost the same density as water and is denser, and when it gets into the water, it does not float to the surface, but goes to the bottom or floats in the water column. There are no proven technologies in the world for its removal from waters, so the main way to eliminate the consequences of the disaster is to collect from the coastline when fuel oil is thrown into the coastal zone.
