Topside Information and Control System

The subsea production system supports open database standards including object-linking and embedding (OLE) for process control (OPC) server compliance, open database connectivity (ODBC) and communications to surface applications. The topside information and control system (TIACS) provides the interface for applications to talk directly to end devices.

The open database structure allows the dissemination of data from all subsea devices to real-time, operational and historic databases. There is also a module for adding manual input to the databases.

Weatherford’s TIACS provides an open system with the ability to perform data collection, storage, presentation, aggregation and expert functionality. A new installation is only a matter of configuration because the software already supports a wide range of channels. Supporting all major SCADA systems, it uses one common infrastructure for integrating all downhole/subsea equipment. The common infrastructure supports OPC-DA (data access), OPC-UA (unified architecture), OPC-HDA (historical data access), Aspen InfoPlus.21® (IP21) through Aspen CIM-IO™, SQL Server™/Oracle, Simatic S5/S7, Teleperm, Modbus and extensible markup language (XML) [ProdML/wellsite information transfer standard markup language (WITSML)].
