Crowcon’s Gas Detectors Ensure Safe Operation at Oil and Gas Terminal in Rajasthan
100 Nimbus flameproof (Exd) detectors supplied Cairn Energy’s Mangala processing facility
100 of Crowcon’s Nimbus flameproof (Exd) hydrocarbon gas detectors have been installed at Cairn Energy’s Mangala oil and gas processing terminal in Rajasthan, India. Supplied via Larson & Toubro, the Nimbus units are located at strategic locations throughout the facility and ensure the safety of workers and equipment by detecting elevated levels of flammable hydrocarbon gases.
“Hydrocarbon gas detectors are required by local legislation,” commented Crowcon’s Indian distributor, Mr Kishore Degwekar of Detection Instruments Pvt. Ltd. “Larsen and Toubro, our customer, purchased the Nimbus detectors as they are certified by the Indian Directorate General of Mines Safety”.
Crowcon’s Nimbus gas detectors have an excellent 10-year proven track record and, as well as having local certification, are also ATEX and UL certified. The detector is also assessed to the globally recognised functional safety standard IEC61508 and is suitable for use as part of SIL 2 systems.
Many thousands of Nimbus detectors are installed in locations across the globe, in all climatic conditions, such as the north of Sweden with its sub-zero winters, the deserts of Qatar, where summer temperatures can exceed 50oC and where sandstorms are common, and hot and very humid regions such as Malaysia.
It is used in all manner of locations, including underground tunnels, oil and gas rigs, oil and gas refineries, over-ground pipelines, compressor stations, turbine halls, pumping stations, sewage works, chemical works, aerosol filling plants, floating production ships (FPSO’s) and power stations.
Designed to be integrated with existing gas detection systems, Nimbus can be used in conjunction with digital communication networks (via RS-485 Modbus) or conventional 4-20mA control systems such as Crowcon’s Gasmonitor.
Rated to IP67, Nimbus functions in even the dirtiest conditions. The optics operate at up to 90% obscuration, with a dirty optics warning light activating at 75% obscuration. An external status light indicates whether the unit is in normal function or fault, alerts users to rising gas levels, and also identifies 22 further conditions for simple diagnosis.
About Cairn Energy’s Mangala oil processing terminal
The Mangala processing terminal covers an area equivalent to 200 football pitches and includes oil, gas, power and water infrastructure. At an eventual length of 670 km, the pipeline will provide access to more than 75% of India’s refining capacity. At the peak of construction, approximately 16,000 workers were involved: 5,000 on the pipeline and 11,000 on the processing terminal.
