The press service of the Northern Fleet announced the successful completion of state tests of the large hydrographic boat "Leonid Century" of the 23040G project. A corresponding act has already been signed, and the flag of the hydrographic service of the Russian Navy will be raised on the boat by the end of December. This ritual will mean that the Leonid Century has been accepted into the Northern Fleet.
The boats of this project are designed to take pictures of the seabed relief at depths of up to two kilometers. In addition, they can be used to produce high-precision areal photography at depths up to 400 meters. "The boat carries out a survey of navigational hazards at depths of up to 100 meters. The vessel is used for the installation and maintenance of all kinds of marine warning floating signs, navigation and hydrographic support for rescue and search operations, as well as for pilotage," the press service of the SF reported.
The technical characteristics of the Leonid Century are also known. Its displacement is about 190 tons. The length of the boat is 30 meters. Speed - 12 knots. The cruising range reaches 1,600 nautical miles. At the same time, the crew of 9 people can stay at sea autonomously for up to 10 days.
Leonid Senchura is the sixth and final in a series of large hydrographic boats built under contract with the Ministry of Defense of the Russian Federation at the Nizhny Novgorod Motor Ship plant. Interestingly, it was towed from the Nizhny Novgorod Region to the Kola Bay via inland water communications for testing.
The history of his name is also interesting. The boat was named "Leonid Senchura" in honor of an outstanding military hydrographer and Arctic explorer, a veteran of the Great Patriotic War, captain of the 1st rank. "He was the head of the Northern Hydrographic Expedition and made a great contribution to the study of the Arctic Ocean, including the relief of its bottom," the press service of the Northern Fleet said.
Under the guidance of Senchura, the Lomonosov underwater ridge was examined in detail, the Gakkel ridge was discovered and studied in detail. For outstanding achievements in this work, Leonid Sergeevich was awarded the F.P. Litke Gold Medal and awarded the USSR State Prize.
I must say that over the past few years, several large hydrographic boats and a small hydrographic vessel "Nikolay Skosyrev" have been accepted into the Northern Fleet. And at the end of last week, a flag-raising ceremony was held on a large hydrographic catamaran "Grigory Shadrin".
