The main task performed by Krylovsky State Research Center was the development of documentation for the conceptual project of a cable vessel, analysis of the existing national and foreign scientific, technical and technological reserve for technical solutions, equipment of cable vessels and related systems in terms of experience in designing, building and operating cable vessels.
In the course of the work, the design documentation for the conceptual design of the cable vessel was developed. Clarified the appearance of cable vessels for the marginal seas of Russia and the Arctic. The main design decisions are substantiated. A list of components has been prepared. The loadings of masses, stability and unsinkability, propulsion, and fuel consumption were calculated for the main modes of operation of the cable vessel.
Proposals were prepared for inclusion in the feasibility study on the creation of a domestic cable vessel and proposals in the basic technology of construction. Technical assignment for the development of the technical design of the cable vessel has been prepared. Methodical solutions and current trends used in the design of cable vessels and equipment for them and the study of the world technical level for the proposed technical solutions are identified.
During the development of the conceptual project, the main characteristics of a large cable vessel were identified. The length of the vessel is 133,5 m; width - 21 m, draft - 6 m, displacement - 10274 t.
During the development of the conceptual design of the cable vessel, its appearance was formed.
The vessel is icebreaking type, has a developed superstructure, in which are located hangars for working with cable, technical and residential premises. In the upper part of the superstructure is the main wheelhouse and the receiving area for Ka-type helicopters - 27. In the aft part of the superstructure there is a backup bridge with cable management stations.
The vessel is equipped with a set of cable-laying equipment providing automated cable laying from the stern of the vessel and repairing the cable from the bow. Also provided is a set of equipment providing and involved in the process of cable laying in ice conditions.
For storage of the cable being laid, there are two main cable tenx and two backup cables, the total mass of the cable being loaded reaches about 5500 tons. The main characteristic feature of cable tenx is its water resistance. The need to create a waterproof storage is due to the testing of the cable by filling Tenx with water.
The developed cable vessel, unlike its foreign counterparts, is distinguished by the ability to work in ice conditions, the coastal zone of the Russian Arctic shelf, and the Far East. In addition to the increased class of ice reinforcements, the cable vessel, which provides not only the possibility of working in ice conditions, but also, if necessary, hidden setting of special equipment. The availability of advanced technological equipment and a sufficiently large number of premises for command and maintenance personnel, if necessary, allows the vessel to be used as a research facility, in a number of options as a diving and, if necessary, headquarters vessel with appropriate additional equipment.
The features of the developed cable vessel distinguish it from typical cable vessels, in particular, those offered by foreign companies and give it the status of "Unmatched in its class". The work was performed under the Federal Target Program "Development of Civil Marine Equipment 2009 - 2016 years" on the basis of contract No. 167-52 / 12 from 30 on July 2012 of the year concluded between the FSUE "Krylov State Research Center" and JSC "Atoll"
