Analysis 3/3: Russian Sevmash Shipyard to introduce block-modular submarine construction
13 November 2020
"The decision in principle has likely been made. It is confirmed by Sevmash, which said in a press release that “a project to switch to block-modular method for the construction of new-generation submarines has been opened.”
The Sevmash shipyard is completing the previous modernization program launched in 2012. It has to develop Sevmash into a modern shipyard capable of building any vessel and comparable to American and West European counterparts in the technical level.
The modernization was financed by several federal programs, including the programs for radiation safety and civilian shipbuilding. Most funds were earmarked by the program to develop the military-industrial complex. The shipyard replaced all the cranes, renewed the tools and measuring equipment, and installed cheaper and more effective lights in workshops.
The overhaul of the construction embankment has been completed. Supplies of steam, compressed air, water, oxygen and other gasses were upgraded. Power cables of the required voltage and frequency were laid.
The berth was the next in the modernization line. Today it can carry hull constructions of 6 thousand tons and transfer them from workshop #7 to workshop #50 and from Sevmash to Zvyozdochka. Sevmash also decreased construction costs and minimized the time. Workshops #55, 50, and 42 have been specialized for end products.
The work in 2020 includes lean manufacturing, advanced control, modern marking technology in the construction of nuclear submarines. Power efficiency is increased and a new line for production with composite materials is prepared.
Large-scale modernization is ongoing in the blacksmith workshop which treats units of future nuclear submarines. In two years, it received 12 new furnaces, upgraded available ones, and is engaged in re-equipment. It is planned to install an automatic electric furnace to treat titanium units for submarines."
