17.02.2015 News Omnisens to monitor the temperature of 65 km underground cable in Southern France

RTE France’s electricity transmission system operator (TSO) is making history in the underground cable world. The project to secure the electricity supply to the Eastern Provence-Alpes region (PACA) includes a section of 65 km which took the record for the longest underground 225 kV AC in the world for this power level. To detect hotspots and monitor the thermal behavior of the cable along the 65 km route RTE selected Omnisens Power Cable Monitoring system. The system comprises fiber optic distributed temperature monitoring, dynamic cable rating and Omnisens Map (GIS) to visualize the asset.

13.02.2015 News Omnisens monitors 56 km subsea interconnector joining Phu Quoc to Vietnam mainland

To help Phu Quoc, the largest island in Vietnam, meet its economic development goals a 56 km subsea interconnector has been installed to link it to the national power grid. The 110 kV Prysmian Powerlink cable, is monitored by Omnisens fiber optic distributed temperature sensing system. Subsea cables are at risk from marine activities, scouring and seabed movement which may alter the environment of the cable and affect its operating temperature. The Omnisens power cable monitoring system senses the temperature continuously, using communication fibers within the cable and detects and locates any changes all along its length. This information is sent by email to the operator so that prompt remedial action can be taken. As Phu Quoc develops so the cable temperature will increase with the additional load. The Omnisens system will indicate when the operating temperature approaches the maximum specified for the cable, so that plans can be made to manage the additional load.

Omnisens is monitoring the temperature and strain on umbilicals used to retrieve oil and gas from 2100 m/7,000ft water depth in the Gulf of Mexico. Two 21 km/13 mile power umbilicals, specially developed to handle the power requirement of seafloor booster pumps, were instrumented with Omnisens fiber optic-based monitoring system to detect early indications of temperature and/or strain events which may indicate a leak, overheating, elongation or other threat to the assets' integrity.

13.01.2015 News Omnisens goes further for London Array wind farm

London Array became the world’s largest offshore wind farm in 2013, its 630 MW generation capacity supplying enough electricity for nearly 500 000 homes. To monitor the temperature along each of its four 55 km export cables, an Omnisens fiber optic-based system was deployed. Thanks to its ability to monitor the entire cable length from a single interrogator the Omnisens system is housed in the Cleve Hill (Kent) on-shore substation, obviating any requirement to go offshore for maintenance. The Omnisens system senses the temperature along the 150 KV cables, supplied by Nexans AS, using dark fibers from those integrated within the energy cable for communication and control. Already sensing the export cable temperature of the two former ‘largest offshore wind farm’ record holders, Walney and Greater Gabbard, the performance of the Omnisens temperature monitoring system (3 m spatial resolution, a temperature accuracy of better than 1 K over the 55 km of each cable, with no dead zones and a measurement time of 10 minutes) enables the operator to see and act upon developing temperature events, whether due to a change in cable’s condition or load.
