All projects of the family 20180 were developed in the Saint Petersburg CMDB "Diamond" under the AA Forst. By the time the true created three projects on a common base: rescue tug (Project 20180), Naval Weapons (20180TV etc.) and marine support vessel (Project 20183). Noteworthy that laying support vessel "Academician Alexandrov" occurred exactly one year after a ceremony that marked the beginning of construction of the transport of arms "Akademik Kovalev." It is planned to build a family of 5-6 ships 20180, created for different tasks.
A fascinating feature of all 3 projects — 20180, 20183 and 20180TV — is the design of the case. Court of Justice of the projects have specific hull shape and reinforced structure with an ice protection. Thanks to this support vessels 20180 family of the least demanding in terms of work in comparison with the previous ships. "Academician Alexandrov" has a body length of about 100 meters, a width of 17.8 meters and a draft of the order of 9.3 m Displacement of marine support vessels a little smaller than the other ships of the family other destinations: 5,500 tons. Regarding the power plant and ship tonnage disk imaging software yet. All data on its performance in the highest rate of properties is limited, the figure is 14 knots. From the photographs, it follows that all vessels are equipped with a family of 20180 bow thruster, consisting of 2-cylindrical channels with propellers.
All projects 20180/20180TV/20183 support vessels are equipped with cargo cranes. Based on the available images, the number of lifting means depends on the specific project. Thus, the "Star" project 20180 has three cranes 2-types of different capacity, as "Academician Alexandrov" Project 20183 — two. From the available data suggest that a larger model used crane has a lifting capacity of 80 tons and a lift height of the boom from 4.5 to 19 meters. With the help of crane ships can without the help of others to make loading and unloading, and work with a variety of special equipment, for example, with scientific instruments designed for deep-sea research.
On the deck of ships to support a back heavy-duty cranes are hatches of the cargo hold. The presence of the latter allows us to assume the application of additional loading of funds placed in the internal volume of the ship, but hard data on this issue yet. Since the entire deck is given over to the courts placement of cranes and cargo hold hatches, the add-mounted in the bow. Before you add a small tank size. In the absence of other areas on the roof superstructures "Sprockets", "Akademik Kovalev" and "Academician Alexandrov" provides landing pad for helicopters. Its size allows soar and take all available at Navy helicopters such as the Ka-29 or the like. The crew of vessels of 20183 consists of 70 people.
Through the use of universal equipment, "Academician Alexandrov," will have a very broad ability to perform different tasks auxiliary wing. Please include the possibility to transport of goods in the internal volume of the body, the ability to create and handling on their own. In addition, bow thruster significantly increases the maneuverability of ships. Depending on the purpose of a specific project view of the family courts 20180 markedly different. For example, a rescue tug "asterisk" is an eighty two cranes and equipment to tow other vehicles. In the transport of arms "Akademik Kovalev" will have only one tap. It might be more powerful than a "star." Towing equipment, as well as on the "Academic Aleksandrov," no.
Another difference between the different versions of the draft vessels 20180 apparently are contours of the nose. "Asterisk" and "Akademik Kovalev" have a traditional assembly with a strong tank and superstructure rising above it. Existing images support vessel "Academician Alexandrov" perfectly clear that his tank is made private, without a separate deck. Plating tank comes up to the add-in and connected to the bottom wall. Some enclosures on the tank is not provided, it may state not to use that part of the ship.
At the current time, lead ship of the project 20180 "asterisk" operated by the Northern Fleet sailors, maritime transport weapons "Akademik Kovalev" in the stocks, and the construction support vessel "Academician Alexandrov," is just beginning. With the available rate of construction all have reason to believe that the last six auxiliary family project 20180, tab which will take place over the next couple of years will be made in the composition of the Navy of the Russian Federation about the years 2018-20.
