Fiber Optic Fieldbus systems in oil production.

Recently developed oil fields in the United Arab Emirates networked with highly available fiber optic field buses. Production has recently started at two new oilfields 50km 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 fibers. 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.
