Floating LNG: How CFD Studies Improve Technip’s Project Development

Printer-friendly versionPDF version

Within Technip organization, Computational Fluid Dynamic (CFD) study is currently playing an increasingly important role at project conceptual or execution stages especially for Floating Liquefied Natural Gas (FLNG) plant. Whether for unit design optimization, equipment performance and layout validation or to ensure the compliance of international environmental standard on the platform, CFD studies are mandatory steps today for Technip.

Until recently, modeling in CFD software was developed from scratch and was the most time consuming phase of the study, despite numerous and necessary geometrical simplifications. However, the recent development of STAR-CCM+® software capabilities for large 3D-CAD model import, through the use of powerful surface wrapping tools, has made possible the use of a different approach in our studies. It allowed us to save a significant amount of time while offering a more faithful geometry with an improved accuracy.

The benefits and main outcomes of this methodology developed by Technip using STAR-CCM+ software will be presented based on an example carried out for an Atmospheric Pollutant Dispersion study for a FLNG.
