LIOS Technology has been awarded to supply the online condition monitoring system for one of the largest 500 kV high voltage cable projects – a milestone in modernizing Russian industry and infrastructure.
The Federal Grid Company of Unified Energy System (JSC FGC UES) selected LIOS’ highly reliable distributed temperature sensing system based on OFDR technology for Russia’s high-technology hub Skolkovo. Load management, optimization and save grid operation describe the key factors for Russia’s federal grid company to equip the 11,5 km double circuit of 500 kV underground transmission cable with the latest fibre optic real time condition monitoring system.

LIOS Technology has completed a power cable monitoring project at a South American mining facility of Codelco in Chile. The Korean made 220 kV, 630 mm 2 XLPE high voltage cable system includes fibre optics in metal tube (FIMT) and supplies pumps, SAG mills (Semi-Autogenous Grinding) and other grinding equipment.
The Distributed Temperature Sensing (DTS) condition monitoring system is installed at the control room at 3500 m above sea level providing continuous 
thermal assessment of the highly loaded power circuit. Among LIOS Technology’s more than 2000 permanent DTS installations this is certainly the one at highest altitude.

The team of LIOS Technology, Cologne
This year LIOS Technology can celebrate its 10 years anniversary. But the activity which formed the basis of today’s LIOS Technology already took its start in 1995. An innovative group within the German cable company, Felten&Guilleaume (F&G) saw an opportunity for developing a distributed temperature sensing system technique for condition monitoring of power cables, and hence making it possible to exploit the full capacity potential of installed high voltage cable routes.
Leaks occurring in underground pipelines constitute a substantial danger for both, human beings and the environment. Oil escaping from pipelines pollutes the earth and ground water.
Leaking gas creates the danger of fires and explosions. In addition, leaks bring about large economic losses. It is extremely important to locate leaks as soon as they occur and to be able to locate small leaks. Until now, monitoring systems have only reacted to large leaks and have not been able to pinpoint them accurately. Oil leaks cause temperature anomalies below the pipeline, whereas escaping gas induces a temperature decrease above the pipeline due to the easing of pressure.
Efficient leak location and the long-term monitoring of gas and oil pipelines can therefore be achieved by measuring the temperatures along a pipeline and observing how these temperatures vary over time. Optical-fibre, temperature-measuring technology presents new opportunities in this connection.
An optical-fibre, temperature-measuring cable is laid along a pipeline, enabling the temperatures in the ground to be measured simultaneously over long pipeline distances with a high degree of locational accuracy.
The sensor cable is completely passive electrically and can therefore by fitted to pipelines where a high risk of explosions exists.

Using optical-fibre, temperature measuring to monitor pipelines makes possible:
- The economical location of leakages and the long-term monitoring of pipelines
- The monitoring of pipeline sections up to 30 km long by means of a system
- The opportunity of linking individual systems to form an overall system to monitor longer sections if necessary
- The quantifying of leakage rates using model calculations
- It is not necessary to empty and clean the pipeline before inspecting it
- Shutting-down the pipeline is not necessary
- Small quantities of escaping oil can be exactly detected and located
- Damage can be identified in its early stages
The measuring system enables the temperature along a section of pipeline to be measured by using optical-fibre sensors. Temperature anomalies caused by leakages are identified via this system and the efficient location of leakages and long-term monitoring of gas and oil pipelines are thus made possible.

From February 18th – 19th, 2010 LIOS was pleased to participate at the second AMRTUR Technical Exhibition (ATE) held at Belait. This year on focus: Latest Innovative Value Added Technology.
AMRTUR’s objective is to provide Integrated Service Solutions to clients in the region. To realize and articulate this objective AMRTUR draws its source of strength and support by collective and coherent of highly motivated local and international “THINK TANKS” and “WORK FORCE”.
At the exhibition various companies gathered specializing in new technologies to assist oil operating companies with well intervention and reservoir monitoring.
LIOS - manufacturer of Distributed Temperature Sensing (DTS) systems - showed its latest EexD zone 1 configuration and AMRTUR staged the world premier of its in-house developed zone 1 fusion splicer.
The exhibition was official launched by the guest of honor Mr. Harrie Krus (Head of Well Engineering & Well Services of Brunei Shell Petroleum) followed by a welcome key note from Lt Col Mahmod Yakop, Founder & Managing Director of AMRTUR.
Latest innovative value added technology products and services were presented and the companies displayed their latest smart well solutions. LIOS – manufacturer of Distributed Temperature Sensing (DTS) systems – showed its latest EexD zone 1 configuration and AMRTUR staged the world premier of its in-house developed zone 1 fusion splicer.
Lt Col Mahmod Yakop recalled: “Installation of LIOS DTS in the Darat Field in Brunei has proven to increase the value of the wells from our customer significantly because of early detection of faulty gas lift valves, resulting in quick repair and increased production.”
This year on focus at ATE, Brunei: Latest Innovative Value Added Technology.
The exhibition was closed with a traditional Lion Dance in celebration of the Chinese New Year.
We would like to thank all the visitors for being so interactive and open minded, and particularly AMRTUR for organizing this first class and professional exhibition. We look forward to the next ATE in 2011.
