In 2016, Sredne-Nevsky shipyard plans to completely replace import composite materials with domestic ones in order to manufacture the composite hulls using vacuum infusion technique. Transition to the Russian producers’ materials is carried out in the framework of the import substitution program and consists of several stages.
The first stage involves a move to domestic composite fabrics, fillers, resins and the adaptation of the production process. The second stage deals with the selection of auxiliary materials such as a vacuum film, a sealing cord and an infusion mesh.
Representatives of research centers including the Krylov State Research Center helped the manufacturers to select materials that meet the requirements of shipbuilders to the full extent. According to Vladimir Seredoho, director of the shipyard, it will take no more than two years to shift the production process to domestic materials, and the final product is supposed to meet international standards.
Goods and services will be purchased from small and medium-sized enterprises, in accordance with the Federal Law “On Procurement of Goods, Works, and Services by Certain Legal Entities.”
Sredne-Nevsky Shipyard has substantial experience in building composite ships. The first fiberglass trawler came off the stocks in 1967. Advances in technology facilitated a transition from old hand lay-up method to vacuum infusion and RTM Light. It has resulted in improved product quality, increased structure’s resistance to water ingress, and resistance to winter conditions.
