Russia Finally Adopts Modular Submarine Construction

January 19, 2021 (Google Translation) – The block-modular method, introduced at Sevmash (part of USC), will reduce the building berth period by 18 months for nuclear submarines. The use of the new technology for creating nuclear submarines will also increase the quality of work and reduce labor intensity due to the assembly of submarine hulls from large block modules of a high degree of readiness.

The concept was developed by the company’s specialists under the leadership of General Director Mikhail Budnichenko together with the Central Design Bureau “Malakhit” and “Rubin”, as well as the Center for Shipbuilding and Ship Repair Technologies. To implement the project, it will be necessary to develop new schemes for the organization and technical equipment of production, create new capacities and modernize existing ones. In particular, it will be necessary to build a new aggregation shop, an additional span of the hull-welding production, replace the cranes of the boathouse No. 2, and modernize the transport and transmission complex.

“Among the tasks are also the introduction of advanced computer-aided design systems based on digital models, new methods of non-destructive testing, technologies for manufacturing ship structures in“ exact geometry ”, changing the procedure for hydraulic testing of the main hull of the submarine – transferring tests from the slipway to a specialized section, as well as organizing parallel manufacturing of technological modules of nuclear submarines and functional modules, saturated with equipment, systems and cable routes, ”explained Alexander Spiridonov, chief technical manager for special projects and armament at Sevmash design bureau.

It should be noted that a number of tasks for the modernization of production are already being solved within the framework of the existing federal target programs and the program of organizational and technical development of Sevmash. For other activities, additional sources of funding are required.
