Structural Strength & Reliability

1. Tests and computations, including development of procedures, numerical models and computer software, in support of design work on ships, submarines and submersible vehicles for:
   • strength and safety of ships and marine structures in order to establish the actual strength and endurance of hulls, structures and their details based on seakeeping, static-load and fatigue model tests and full-scale trials, and numerical analysis
   • strength and safety of submarines, deepwater vehicles and equipment in order to establish actual diving depths of their hulls based on static-pressure, life endurance and certification tests of full-scale hulls, their models, materials and outboard equipment, and numerical analysis
   • ship and submarine vibrations in order to reveal excessive vibration underway in hulls, machinery and equipment
   • surface ship and submarine hull resistance to explosion effects
   • resistance of ship structural protections against high-velocity projectiles;
   • strength of metallic and non-metallic structural materials under dynamic (including high-velocity) loads
   • shock resistance of marine power plants
   • torsional and longitudinal oscillations of main engine and auxiliary machinery shafts
   • strength and buckling resistance of sonar domes
     
     
2. Development of guidelines, normative and regulatory documents for designing and upgrading ships, submarines and submersibles in terms of their structural strength and vibrations underway:
   • selection of hull materials and structures
   • evaluation of service suitability and life
   • development of structural protections
     
     
3. Condition evaluations for material specimens, details and structures using non-destructive test technologies
   
   
4. Development of structural condition diagnostics systems
   
   
5. Design of ship structures
