Communications/Telemetry
are designed for the harsh environments encountered by the energy sector. Meanwhile, Huawei has completed
a project to install a communication and SCADA system for the 1,304km Kazakhstan segment of the Central Asia- China gas pipeline.
Among the challenges that Huawei had to tackle were the five compressor stations, two metering stations and over 60 valve chambers – all distributed in deserted areas. Te company also had to deal with legacy transmission and communication devices, laying fibre optic cable, mobile communication vehicles, earth stations for satellites and intrusion detector systems. Te project also required complex transnational coordination as the Kazakh section joins the Uzbek section of the pipeline at one end and the Chinese section at the other. At no point could one section lose contact with the other. To ensure the real-time, uninterrupted transmission of data, Huawei proposed a solution using optical transmission as the primary channel and satellite transmission as the auxiliary channel. To guarantee the communication
coverage along the pipeline, Huawei provided wireless-cluster and short wave-system solutions, which established wireless and shortwave stations in each gas compression and metering station. Furthermore, three emergency communications vehicles were used to ensure uninterrupted communication along the whole line on standby.
Redline RDL-3000 outdoor wireless networking systems provide secure reliable TCP/IP transport for applications in a wide range of fixed, portable and full-motion terrestrial and seaborne deployments. Many of the systems include integrated GPS for location services.
As a result of the project, the number
of staff required at the compressor and metering stations has been halved. Also the accuracy of the transnational measurement data via the SCADA system has halted disagreements that previously occurred between owners, customs and commodity inspectors from the countries involved in the pipeline. Finally, Apprion has launched the latest addition to its ION Mustering Application – the ION Mustering Tower. Tis is a stationary access point for real- time personnel check-in within mustering areas during emergencies. Te company says its new product is the first wireless, solar-powered mustering tower designed specifically for industrial facilities such as oil and gas plants. Te tower uses a visual strobe light for mustering notification during emergencies, ensuring that it will be seen by personnel. Once employees arrive in the mustering area they can automatically check-in via a wireless badge scan and the tower’s WiFi reader updates the system that the employee is safe. Tis automated system and efficient backhaul reader eliminates manual processes and provides real-time mustering and personnel safety location during emergencies. “Apprion understands the importance of safety at industrial facilities and values its customers’ input when designing new products for facilities like ours,” said Ryan Kindred, lead electrical design engineer at BASF, Freeport (Fig. 1). l
Mobile app gives 48 hours’ notice of sandstorm U
nique System FZE, part of the Unique Maritime group of integrated turnkey subsea and offshore
solutions providers, has teamed up with the Geodesy and Hydrographic Survey Section of Dubai Municipality (DM) to launch a mobile app that will enable users to know about an approaching sandstorm 48 hours in advance. Te launch is in succession to last year’s unveiling of UAE’s first sandstorm forecasting system (SFS). Dubai is the first emirate to use the SFS, which gathers information from its automatic weather stations (AWS) as well as the World Meteorological Organisation. Trough the AWS, the information goes to an Etisalat tower from where it gets relayed to the servers at DM.

Te project, which was handled by Unique System FZE. has established the sandstorm prediction and weather forecasting model for Dubai using the existing upgraded five tide and meteorological stations and eight terrestrial meteorological stations and the two offshore data buoys. During the upgrade, new rain gauges were also installed so as to complete all stations with rain measurement. Te data from each station is transmitted to a central server at DM’s survey department. Tere it is used to create the respective forecast models. Tese in turn are analysed by a professional meteorologist to create daily forecasts about the sandstorm and associated visibility. Te mobile app can be downloaded on all the latest versions of the Android platform. l
