SEVMASH to Shorten Construction period for Nuclear Submarines

The block-modular method introduced at Sevmash will make it possible to shorten the slipway period for the construction of nuclear submarines by 18 months. 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 Malakhit Marine Engineering Bureau and the Rubin Central Design Bureau, as well as the Shipbuilding & Shiprepair Technology Center.

To implement the project, it will be necessary to develop new schemes for the organisation and technical equipment of production, create new capacities and modernise 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 modernise the transport-transfer 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 specialised section, as well as organising parallel manufacturing of technological modules for nuclear submarines and functional modules, saturated with equipment, systems and cable routes,” explained Alexander Spiridonov, chief technical manager for special projects and armament at the Sevmash design bureau.

The USC notes that a number of production modernization tasks 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.
