Brugg Cables - the largest company within the Brugg Group, which was founded in 1896 - is a leading developer, manufacturer and supplier of engineered sensing-cable-system solutions. Its product range covers the transmission of signals and power, including fibre-optic, low-voltage and high-voltage cables.
The company's range of fibre-optic sensing cables monitors physical parameters such as strain, temperature, acoustics, vibration, pressure, humidity and intrusion detection in real time. For the different parameters and values, there are optimised optical-measurement techniques that use the back-scattering effects of the fibre optics. These methods include Raman, Rayleigh scattering, Brillouin and Fiber Bragg Gratings.
Brugg Cables offers an open technology platform and application-optimised cables and accessories for these sensing methods. This delivers results with perfect sensitivity, exact values, constant quality and adaptability to the environment.
The fibre optic is a distributed sensor, and the resolution, maximum length and time delay depends on the interrogator unit only, which is installed at one end of the fibre-optic cable. For today's interrogators, the length of a sensor can be longer than 50km with a resolution as short as 10mm. Of course, extended length combined with high resolution increases delay time. Development of interrogators is advancing quickly, and a reliable cable will support future improvements due to the stable qualities of fibre-optic cables.
Brugg Cables offers the complete range of cables and services that have been developed and successfully used for over 25 years, including:
Despite the reliability and versatility of fibre-optic sensing, it is a also cost-effective solution that is able to evaluate the mechanical health of large structures, performs reliability and damage assessments, generates the necessary data to optimise energy production and transfer, and detects incidents early.
Fibre-optic-sensing technology saves money because it optimises processes to prevent the loss of precious energy resources, such as oil and gas. The technology also helps to reduce damage and down time, and gain the maximum possible output of the productive facilities. Fibre-optic sensing monitors the effective ageing process of the operational facilities and may, therefore, extend the life cycle of expensive assets.
In the oil and gas industry, fibre-optic cable sensing systems are widely used in different sectors such as upstream, midstream and downstream, and on structures, in risers and umbilical cables.
The products are adapted and available for versatile environmental conditions such as onshore and offshore, and subsea. The technology is proven in many applications, and cable installations are made for oil wells, reservoirs, pipelines, LNG terminals and refineries.
The technology functions in applications such as:
