Abstract
The article presents a solution ensuring the automated process control system (APCS) of underwater oil and gas production to function in a heterogeneous information environment. The authors consider the necessity to apply hazard identification and risk assessment tools to further control of the process hazards. The modules of expert and simulation model design may serve as such tools. Furthermore, the review of APCS control schemes is given, and a comprehensive scheme of APCS block integration and the composition of the unified APCS software package are proposed. The most suitable scheme for controlling the heterogeneous information environment is the scheme of direct digital control. However, it has a distinct disadvantage which appears in case of a computer failure. One way to avoid this situation is to arrange a computer backup or replace one computer with a system of machines (a cluster). The unified cluster uses the XML-format for the data exchange. This allows for cluster functioning in a heterogeneous information environment. A centralised data repository consisting of a database and file storage is used for storing the incoming data #COMESYSO1120.
