Abstract: The invention relates to a system for access, exchange, analyses and design of information relating to industrial plants having a substantial complexity like petrochemical sites or production facilities for semiconductors, the system comprising at least a set of mutually connected computers containing the information and at least a client computer functioning as user station to enable the user to access the information to the information, wherein the system is adapted to create a virtual reality for the user on the client computer representing the premisses of said industrial plant and that access to the information is obtained through objects in said virtual reality which bear a relation to the information concerned. The virtual reality aspect has the substantial advantage that a person looking for information is automatically urged to the location where he or she would expect the required information to be in real life, thus shortening the look up time.
