WORK EXPERIENCE

1961 – 1964. Senior Design Naval Architect (earlier Design Naval Architect).
Baltic Ship Repair Yard, Tallinn, Estonia (One of the biggest in USSR)

• Various aspects of ship design, e.g.:
  • calculation of general stress distribution
  • preparation of trim and stability booklets
  • equipment foundations
  • docking calculations

1964 – 1967 Post-Graduate Student.
Leningrad Shipbuilding Institute, Leningrad, USSR (Oldest Russian maritime university)

• Towing and seaworthiness tests in the towing tank
• Application of the world first method predicting resistance of thin hull catamarans in function of variation of their main dimensions

1967 – 1970. Senior Research Specialist (earlier Junior).
Central Research Institute for Merchant Marine, Leningrad. (Main research center serving Russian Merchant Fleet)

• Initial design stages of arctic barge-carrier "Sevmorput"
• Calculations Booklet to predict technical quality of new ship concepts (barge-carriers, trade helicopter-carriers, other)

1970 - 2001. Leading Research Specialist (earlier Senior)
Krylov Shipbuilding Research Institute, St.Petersburg, Russia. (Russia’s biggest and world-famous center of shipbuilding sciences)
Concept design, research and development of multihulled ships.

• More than 30 new concept designs, including:
  • concept designing of a new type of super-fast ship (speed twice that of then-typical fast vessel, at improved seaworthiness at all speeds - ferries, patrol and battle ships, displacements 20-1000 t, speeds 80-130 kn);
  • concept designing of a new SWATH hull form for all-weather fast ferries, motor yachts, patrol and battle ships, aircraft and helicopter carriers and the like, displacements 15-3,500-60,000 t, speeds 30-70 kn in Sea State 3-6;
  • economical SWATH-platforms for new types of vessels, like transatlantic and feeder container-carriers with up to 40 kn speed;
  • all-weather passenger ships for remote coastal operation and luxury passenger cruise ships;
  • small economical shallow-draft fishing and river transport vessels, tugs with tractor motors, ship-platform with snake propulsor, etc.
• Heading complex scientific and designing programs (including collaboration with design offices).
• Development of design software for multi-hull vessels (both conventional and SWATH).
• Development of and testing the world first systematic model series of catamarans, trimarans, twin- and triple-hulled SWA ships, and ships with outriggers, including collection and analysis of full-scale data and propulsion data.
• Prototype tests in waves, development of complex seaworthiness comparison method. Systematic calculations of plate thickness and hull weight for SWATH and catamarans.
