In maritime sector we provide verification of structural designs (newbuildings and conversions) of all ship types:
\ngeneral cargo ships, multi-purpose dry cargo ships, bulk carriers, oil tankers, chemical tankers, container ships, ro-ro and ro-pax ships, car carriers, passenger ships, naval ships, special ships (e.g. tug, ice breaker, dredger).
<\/p>\n

Typical analyses<\/o:p><\/span><\/h2>\n

1.\tPrescriptive and direct strength analysis of hull structures in accordance with rules
FE structural strength analysis usually performed at three levels:<\/p>\n

    \n
  • Global direct strength analysis to assess the overall hull girder response<\/li>\n
  • Partial ship structural analysis to assess the strength of hull girder structural members, primary supporting structural members and bulkheads<\/li>\n
  • Local structure analysis to assess detailed stress levels in local structural details<\/li>\n<\/ul>\n

    2. Fatigue analysis<\/p>\n

      \n
    • Fatigue due to cyclic stresses from wave loads and ship motions (High Cycle Fatigue).<\/li>\n
    • Fatigue due to low cyclic stresses from loading-unloading cycles or crane operation cycles (Low Cycle Fatigue).<\/li>\n
    • From simplified approach to extensive full stochastic analysis.<\/li>\n
    • Based on FE stress analysis - nominal stresses, hot spot stresses or local stresses at free plate edges<\/span><\/li>\n<\/ul>\n

      3. Hydrodynamic \/ seakeeping calculations - direct wave load analysis<\/p>\n

        \n
      • Determination of extreme loads and relevant load cases for ultimate strength calculations.<\/li>\n
      • Determination of dynamic loads applicable in fatigue strength assessment.<\/span><\/span><\/li>\n<\/ul>\n

        4. Vibration analysis of hull and superstructure<\/span><\/p>\n

          \n
        • Global hull and superstructure vibration based on complete ship model<\/span><\/li>\n
        • Vibration analysis focused on large parts of decks and bulkheads, based on complete ship model<\/span><\/li>\n
        • Vibration analysis of local structures (plate fields and stiffeners)<\/span><\/li>\n<\/ul>\n

          5. <\/span>Vibration analysis of masts and hull appendages<\/p>\n

          6. Vibration analysis of foundations and machinery units<\/p>\n\n\n\n\n\n\n
