October 8, 2020 (Google Translation) – At Sevmash (part of the USC) preparations are underway for the introduction of modular technology for creating nuclear submarines. It is a method of assembling ships from large blocks loaded with equipment. It is assumed that the use of modular technology will make it possible to reduce the labor intensity and terms of building nuclear submarines.
Nowadays, a modular-modular method is used in production, which was introduced during the construction of third-generation nuclear powered ships. According to this method, the finished, but not yet tested, block sections of the future nuclear submarine are transferred from the hull-welding production to the slipway, from which blocks are formed that pass the stage of hydraulic tests. After its completion, the sections are again disconnected. This technology lengthens the construction period of the ship. When using the block-modular method, it is planned to reduce not only the slipway period, but also the costs due to the transfer of a colossal amount of work from the slipway to specialized workshops.
“In 2016, under the leadership of General Director of Sevmash Mikhail Budnichenko, proactive studies of a new technology for the construction of nuclear submarines were started, – said the project manager, head of the PKB bureau Alexander Spiridonov. – A working group was created with the participation of submarine designers. Within the framework of the USC we have opened a project to create a block-modular method and transition to the construction of new generation boats using this technology. ”
To introduce a new method of building ships at Sevmash, production facilities are being modernized, a new infrastructure is being created. It will also be necessary to build new logistics for the supply of equipment and services. Now a project for the introduction of the block-modular method is being developed and is undergoing a discussion stage in the relevant departments. In the future, Sevmash may become the first enterprise where this innovative technology will be applied in submarine shipbuilding.
