Real Cases
Real-time Monitoring, Control, and Management of Assets for Oil Drilling Platform Assets
Company: ONGC (Oil and Natural Gas Corporation), Ltd.
Location: India
System Introduction
ONGC produces 77% of India’s crude oil and 81% of the country’s natural gas. The goal of this project was to manage manufacturing and assets of 45 offshore and onshore drilling stations remotely from the enterprise control center. ONGC entrusted ABB Bangalore to integrate different SCADA systems into an enterprise-wide SCADA network for monitoring oil drilling platforms and to set up the communication network between the enterprise control center and 45 ONGC-owned drilling platforms for remote data collection. The system establishes a TDMA radio access network to link the control level network and enterprise level server. Each drilling platform uses HART instruments connected to redundant RTUs (Remote Terminal Units) to control drilling facilities on the floating platforms. The RTUs supply data over an Ethernet network in real time. The high bandwidth provided by Moxa’s EDS-408A, which is an industrial managed redundant Ethernet switch with DNV and Class I, Div.2/Zone 2 certifications, enables safe communication between field operations and the control station.
