Wellstream International Ltd

SolidWorks 3D CAD helps Wellstream to efficiently and easily adapt pipelines to specifically fit customers needs. SolidWorks simulations helps Wellstream to see how the structure will perform once it’s deployed.

About Wellstream International Ltd

Wellstream's vision is to provide "innovative pipe solutions for tomorrow's energy production". They achieve this through a comprehensive portfolio of pipeline products, established dynamic flexible risers and static flowlines for deep and ultra-deepwater environments, FlexSteel™ for use in onshore applications and high temperature/high pressure products for drilling and service applications.


The ocean’s harsh weather and constant movement make pipeline breaks a constant concern that can cost offshore oil operations up to $1 million per day  in lost revenues. Wellstream required SolidWorks to design customised pipelines flexible enough to roll with waves and currents, yet strong enough to contain thousands of gallons of oil and gas, pumped at high pressures.


Engineers at Wellstream use SolidWorks to specially adapt pipeline supporting structures to customer’s specific needs, then simulate how the structure will perform once its deployed.


  • Specially adapt pipeline supporting structures to customer's specific needs
  • Simulate how the structure will perform
  • Quick to build 3D models

Previous CAD

"Sub-sea oil and gas flow lines must be reliable and they must last a long time. Designs have to be robust, the fit between elements must be perfect and every component has to satisfy stress and fatigue requirements. We use SolidWorks software to create designs and SolidWorks Simulation to perform stress assessments. I create a 3D model, apply loads to determine stresses and use Simulation to perform analysis on specific components. Its very quick to build the models, run the tests and figure out the behaviour of the assembly in more detail."
