Tests of the world’s largest flexible container МK-14-10

The Krylov State Research Centre has conducted unique tests of the world’s largest flexible container engineered and manufactured by Flexible Bulk Container Corporation:

Static tests were conducted equivalent to lifting of a 14t container with top slings, the maximum overload factor of 6. The container sustained the proof load.<

• Set of documents governing structural strength analysis for surface ships, under the order of Rosoboronexport.
• Conceptual design documentation for high-end engineering facility to be operated in extremely severe conditions of deep Arctic waters.
• Standardized prediction technology for ice loads and ice strength to be applied both for ice-going vessels and ice-breakers and FPSO of Arctic fleet.
• Breakthrough structures of polymeric composite materials and design principles thereof for advanced high-speed, passenger and fishing vessels up to 70 m in length. Infusion and RTM-methods used thereto enable significant reduction of structure weight, increase their service life, improve sanitary & hygienic labor conditions during vessel construction.

• Comprehensive vibration tests on research & expedition vessel «Akademik Treshnikov» during sea acceptance trials and Antarctic trip.

• Special-purpose acoustic-emission system for on-line monitoring of weld joint quality under the order of NIKIET JSC.

• Predictions for LNG carrier ice reinforcement scantlings. The obtained results have been used in LNG carrier conceptual design developed by the Krylov Centre under Yamal-LNG Project.

• Determination of ice loads, ice strength and development of ice reinforcements to ensure design of ice-resistant semi-submersible floating drilling rigs Polyarnaya Zvezda and Severnoe Siyanie.
• Vibration strength tests on structural units and joints made of polymeric composite materials.
• Comprehensive analysis of statric and fatigue strength and crack resistance of weld and thread joints to develop aluminum catenary riser (АСРR).

Acoustic emission tests to check the erection welds of air & gas pipelines on submarines under construction at Admiralty Shipyards

The purpose of these tests was to check the quality of erection welds in air & gas pipelines on submarines under construction during pneumatic strength trials of the pipelines using the acoustic emission techniques.

The acoustic emission tests are performed using multi-functional AE systems of KAEMS type.
The AE inspections supported the acceptance of air & gas pipelines of 01570 & 01339 Projects.

Composite vibration isolation built-up coupling with enhanced vibration damping features.

Innovative design of composite vibration isolation couplings has been devised featuring high dissipative properties with substantial reduction of dynamic loads on ship shaftings and power plants induced by unsteady ship motions.

New ice belt design for ice-resistant offshore platforms and other marine structures & vehicles.

Results achieved:

• 20% labor reduction in manufacturing of steel & concrete grillage structures with external plating reinforcement along with enhanced reliability of plate joining.
• 40 year service life of ice-resistant offshore platforms subjected to ice loads and extreme cold temperatures reaching -45°С.
