Operating safely
September 2009, Fieldbus & Industrial Networking

Fibre-optic fieldbus systems in oil production.

Hirschmann networks recently developed oilfields in the United Arab Emirates with highly available fibre-optic fieldbuses.

Production has recently started at two new oilfields 50 km southwest of Abu Dhabi city, Rumaitha in the countries interior and Al Dabb’iya on the coast. The daily production capacity of the fields is about 100 000 barrels. The facilities for producing, storing and metering the crude oil have been in operation since late 2005. Operating safety is paramount here, so the process control system has been designed with full redundancy, and data is transmitted between the controllers and the remote I/O stations via fail-safe, redundant optical fibres. The danger of explosion that is inherent in such facilities presents a particular challenge. This challenge must be met with ATEX approved devices that are also capable of withstanding high ambient temperatures.

Project details

The process control is designed as a redundant system to specifically meet the customer’s demand for high process data availability. The process control units constructed by Honeywell provide a primary and a secondary Profibus DP interface with the remote I/O stations. HART information is recorded via an independent service bus using an RS485 interface. Optical cables and redundant optical rings ensure an exceptionally high level of operating safety. The cabinets, installed in explosion protection zone 2, include devices for properly isolating the intrinsically safe signals that are primarily used here for transmitting to zone 1 and zone 0. The power supplies for the remote I/O stations are designed redundantly. The cabinets have been engineered to prevent heat accumulation and they are also equipped with solar protection means. Otherwise, it would not be possible to keep the electronic components in the cabinet sufficiently cool in desert conditions.
