BACKGROUND

Krylov is the principal shipbuilding research institute in Russia. Originally it only did work for the Soviet Navy. Now work is done at Krylov for all disciplines of ship science. The institute has seven divisions:

  1. The Design Research Center. The center studies trends in development and conceptual designs for ships, and handles the preproposal stages of ship design. This division was originally responsible for all shipbuilding in the USSR.

  2. Hydro- and Air Mechanics Division. This division is responsible for hydrodynamic and aerodynamic testing and design.

  3. Strength, Vibration, and Structure Division. This division is responsible for design and test methodology for materials, fabrication techniques, and structures.

  4. Acoustics Division. This division is responsible for minimizing noise emitted from ship systems.

  5. Nonacoustic Ship Signatures Division. This division is responsible for minimizing electromagnetic noise from ship systems.

  6. Marine Power Plants Division. This division is responsible for all aspects of power plant design and integration.

  7. Nuclear Power Plant Division. This division is responsible for all aspects of marine nuclear power plants, including shielding, safety, and control.

Krylov also has a large workshop and model-making capability that supports all of the divisions.

Krylov has 5,000 employees, 2,500 of whom are employed in research. The institute has a very large facility that covers 80 hectares. The institute is considered very similar in facilities and in organization to the David Taylor Naval Research and Development Center's laboratories in the United States.

RESEARCH AND DEVELOPMENT ACTIVITIES

Tow Tank Test Environment

Krylov has a wide variety of test environments. There is a linear tow tank 1.4 km long, a circular tank, and a tank for testing simultaneous response to wind, waves, and current in a seafaring test tank. There is a high-speed test tank for testing hydrofoils and other high-speed designs. There is an ice model test tank to evaluate effectiveness of ice breaker designs, and a test environment for testing air/water interaction for ground effect aircraft, and so forth. There is also a propeller design test environment specializing in anticavitation, and air and water interactions such as in a hydrofoil design.

The panel members were able to visit the structural test facility and the pressure test facility. Krylov can test and life-cycle full-size structural components. The institute has a laboratory with a reinforced floor, reinforced walls, and an overhead crane. Krylov has a large hydraulic power source which can drive up to 96 channels with up to a total of 15,000 tons of force or 40 to 600 tons/channel. The institute also has an automated computer control system and a 3,000 point data acquisition system. This facility has the capability of studying crack initiation and propagation using acoustic emissions. It also has the ability to control temperature of the material under test down to -110C. The panel saw a large structural member that was being life-cycled for certification of the design by Lloyds of London.

This facility is available to subcontract test services at $1,500 day and fabrication of test structures for about $0.50/lb.

Pressure Test Facility

Krylov has a large pressure test tank 1.8 m in diameter and 5.5 m deep, capable of testing up to 1,500 atmospheres, and of cycle testing at a rate of 15 cycles/hour.

The panel also saw a larger pressure test tank 3.2 m in diameter and 9.5 m deep and capable of testing to 1,000 atmospheres. These facilities have the capability to test functional equipment such as motors, thrusters, and robotic arms at pressure. When testing pressure hulls, they can measure roundness, thickness, and weld integrity before and during the testing. The panel saw a 2.4 m diameter titanium sphere certified by the Russian Registry to 4,000 m, which would sell for $1 million.

One of the functions of the institute is to do failure analysis of accidents and marine problems. This helps improve the institute's knowledge of design and testing for future designs.

Krylov is responsible for testing and test methodology. The institute's scientists and engineers test for the shipbuilding industry, set design rules for deep water submersibles, and are currently evolving new rules for the design of icebreakers. They also specify the testing methodology for verification of new concepts in ship design.

Krylov is starting a new area of research in the area of gas and oil production. The institute would like to use its knowledge of structures and testing in marine and land-based deep drilling and in pipeline systems.

Two years ago Krylov designed and built a 6,000 m ROV called Uran. It was a tethered vehicle that had small vehicles on 100 m tethers operating from it.

SUMMARY

Krylov is the leading organization in Russia (and, in many areas, in the world) in the academic knowledge of ship building and of testing structural components. For many years, the institute oversaw all of the ship building activity in the former Soviet Union. Krylov is now expanding to include work in all disciplines of ship science. The institute's test facilities and design analysis capabilities are available to the world market at what Krylov believes is a very competitive price. The institute is also contributing to test standards and methodology.

Krylov showed the panel very impressive facilities for structural testing, pressure, and temperature testing. The institute also has a wide range of tow tank facilities, including a 1,400 m long tow tank facility. These are effectively described in Krylov's brochure.

Krylov is analogous to the David Taylor Naval Research and Development Center in Carderock, Maryland.
