Zvezda to save RUB 200 million with its innovating welding technology
Zvezda Shipbuilding Complex (Bolshoy Kamen, Primorsky Territory) is introducing an innovative technology of welding T-beams intended for reinforcement of ship hulls. The new technology is to ensure an economic effect for the coming 25 years which is to exceed RUB 200 million, says Information Policy Department of Rosneft.
To ensure higher productivity of the line manufacturing T-beams, Zvezda specialists conduct seam welding through inductive heating of conducting materials with high frequency and high amperage current. This method applied by Russian shipyards for the first time lets increase production efficiency by 40% and exclude process induced distortion typical for conventional methods of welding. Removal of such distortions used to take half of the production cycle time. Reduction of welding time is among the crucial tasks for designers.
Inductive heating technology will let enhance energy efficiency of the company, reduce the cost of production and contribute to the process automation.
Inductive heating ensures high level of environmental and fire safety.
Zvezda Shipyard is being established at the premises of the Far Eastern Shipbuilding and Ship Repair Center by the Consortium of Rosneftegaz, Rosneft and Gazprombank.
The product line of Zvezda will include vessels with a displacement of up to 350 thousand tons, elements of offshore platforms, ice-class vessels, commercial vessels for cargo transportation, special vessels and other types of marine equipment of any complexity, characteristics and purposes, including equipment that was previously not produced in Russia due to the lack of necessary launching and hydraulic structures.
Pilot workload of the Shipyard is secured by Rosneft, which signed an exclusive agreement with FESRC on placing with the Shipyard all orders for new marine equipment and ship building. As of today, the backlog of orders numbers 12 Aframax tankers (length - 250 metres, breadth - 44 metres). Both main and auxiliary power units can run on conventional fuel and on natural gas.
