LNG Tank Analysis and Design System

Software Specification

LUSAS LNG Tank System

A specialised LNG tank analysis and design system which includes all of the elements, material models, modelling, analysis and results processing capabilities of LUSAS Civil & Structural plus with additional facilities to allows engineers to automatically create a range of models of full containment circular tanks from user-defined parameters. From these models, a range of analyses can be performed, and design checks can be optionally carried out for specified load combinations.

Analysis capabilities

  • Linear static stress analysis
  • Linear buckling
  • Natural frequency analysis
  • Linear dynamics including forced response
  • Interactive Model Dynamics
  • Fatigue analysis
  • Linear cable tuning analysis

and also includes these software options:

  • Fast solvers
  • Advanced Interactive Modal Dynamics (IMD Plus)

  • Nonlinear analysis

  • Dynamic analysis

  • Thermal / Field analysis

which allow for 

  • Geotechnical / Soil-structure interaction analysis

And when used with these purchased software options also allows:

  • Steel frame design
  • RC frame design
  • Heat of hydration analysis

  • Composite FRP
