FIELD: shipbuilding; water craft. SUBSTANCE: water craft is made from combination of steel and concrete; water craft has hull or submersible floating portion made from concrete with concrete pillars rising from it and extending to steel deck portion. Steel pillars are built separately and may be fully equipped before mounting them on concrete portion and securing them in this portion. Separating line between concrete and steel in support lies at some distance from deck support (point of application of impact load) where concentrated mechanical stresses from concentrated loads exerted on deck support are distributed along body of steel support to low and relatively even level. EFFECT: enhanced stability of water craft. 8 cl, 7 dwg
