Key Features:

Oil and gas forms a great concern to many nations, being the main attribute in the a country’s economic growth and welfare. Driven by the above realization, governments are continuously seeking new Oil sources.
New as well as current Oil fields demand the utilization of the latest communication techniques and technologies. In order to setup a secure and reliable two way communication channel for monitoring, as well as handling reports that require massive amounts of data and transmission power.

The Challenges

Petrofac needed a new solution replacing an old wireless radio system in a remote site, due to loss of the LOS (Line of sight) in urban extension process. The new system that needs to be installed must ensure reliable operation, and reduce data loss and failure problems that the old system suffered from.

The key features that the new system required:

• Provide secure and reliable communication
• A good range of operating temperature
• Modbus functionality to be compatible with the installed SCADA system.

The Solution

After a number of site visits, Xceltra decided to provide Petrofac with the M2M remote connectivity solution. This decision was made based on the following factors:

• The sites were extremely far, and had good mobile network coverage.
• Upgrading an old Radio system, required additional installation costs as well as carrying out a new path study.
• Using the wired solutions wasn’t an option.


The designed M2M remote connectivity consisted of a Cellular (GPRS/Edge) Modbus Gateway with the following features:

  • It achieved the desired speed.
  • A Firewall and SSH to ensure secure Communication using static IP SIM cards.
  • Modbus serial-network gateway to be connected to the SCADA directly.
  • Temperature ranges: –40 to +75 °C.
