FLACS-VRApplying Virtual Reality to Safety Training

Dr Pascal Le Gal

SVP Global Software Sales, Gexcon

FLACS User Group Meeting 8th – 9th November 2016 Paris, France

Develop Virtual Reality (VR) tools for application in the oil,

gas and process industry with the purpose of enhancing

safety through improved risk communication, interactive

learning and training.

Integration of 3D accident scenario visualization into realistic environment

models through use of:

True 3D Engineering geometries

Realistic landscape/environmental models

Accurate 3D CFD consequence modelling
