Oil & Gas Transportation

oil transportationANSYS FEA and CFD simulation software has been used extensively in the design and engineering of the Oil & Gas transportion devices and procedures. A number of SimuTech customers are using ANSYS FEA and CFD software for Oil & Gas transportation projects.

SimuTech has completed many consulting projects directly associated with the transportation of Oil & Gas.

In addition to simulation software and services, SimuTech is a leader in vibration diagnostics to the Oil & Gas industry.

Oil  Gas Transport

Design ElementChallengesSimulation Benefits
Slug Catcher at Hannibal Terminal
  • Slug catcher separates residual liquid from gas at end of pipeline
  • Gas pipeline from off-shore field to land-based Hannibal terminal
  • Every few days a sphere is passed through the pipeline to remove residual liquid
  • Plan to increase pipeline capacity
  • Does capacity of slug catcher also have to be increased?
  • Provided a platform to evaluate the slug catcher performance at the pick capacity
  • Established that the existing geometry can handle peak loads, eliminating the need to make a replacement purchase of over $25M
  • Established that any excess liquid will move downstream as aerosol
  • Provided the ability to model free surface flows, such as motion of slugs in complex piping and flow systems
Umbilical, Risers, Flexible Piping
  • Very high reliability requirements
  • Transmitting signals and transporting flows over much longer distances
  • Tubing exposed to harsh conditions
  • Develop reliable piping for variety of offshore applications
  • Requires structural reliability while handling thermal stresses and fatigue
  • Manufacturing of multi-tubes including the steel wrapped around
  • Complex multi-layer, varying material manufacturing channels
  • Build the core tubing and additional helical tube models in an easy to use environment 
  • Account for different material proprieties
  • Evaluate thermal, flow loading and bending stresses. Account for all applied loads including
    • High bending angles
    • Hydrostatic loads
    • End tension
    • Gravity
Flow Assurance
  • Deeper water depths leads to complex tubing design and manufacturing concerns including
    • Depositions
    • Wax formation
    • Thermal management
    • Erosion inhibitors
  • Active heating, insulation and bundle design in harsh environment and deep waters
  • Ability to optimize thermal and structural behavior of tube bundles used for deep and ultra deep waters
  • Can develop technology for fouling, wax and hydrate formation by obtaining detailed thermal management information, including insulation in the analysis
  • Thermal uniformity for start up and shut downs
  • Thermal stress and fatigue
LNG Spill and Fire
  • Accident scenario and safety concerns
  • LNG leaks and the dispersion in the liquid
  • LNG evaporation and tracking of the dispersed gas
  • Vapor cloud formation and ignition as the vapor cloud reaches the water surface
  • Spreading of the pool fire and the associated 
  • Multi-body hydrodynamics
  • LNG transport and tank design
  • Safety and risk assessment
  • Pool fire modeling
  • Multi-body hydrodynamics
