Omnisens, a provider of continuous, long distance monitoring systems for energy cables, has announced that the company has received investment from SVC Ltd.
The export cables, which transmit the power generated from the offshore substation to the onshore one, are exposed to many potential risks as many windfarms located more than 20 km (12 miles) offshore and in relatively shallow water (less than 100 m (328 feet)). Existing pipelines and cables may cross the cable route. Completely changing the environment where the cable is located, tidal activity may lead to seabed migration. Although none of this is visible, fishing and marine activity may damage the cable with anchors and dropped debris.
“From their success in projects demanding cost-efficient, long distance, accurate monitoring, the Omnisens systems are clearly answering a market need," said Andreas Koopmann, chairman of the Investment Committee of SVC in a press release. The systems are considered accurate at significant distances, even those greater than 50 km (31 miles).”
Enabling the operator not only to monitor the condition of the cable, but also to feed the temperature into a dynamic rating system so that the cable loading can be optimized, Omnisens' Ditest, Based on Brillouin-based distributed fiber optic sensing, is able to resolve the temperature to within 1 degrees C at each point along 50 km of power cable continuously from one interrogator, the company stated in a press release.
Recently, the company announced that the company was exhibiting on the C1 stand from the 20th to 22nd of September 2011 in Rio. The DITEST AIM implemented in the Peruvian Andes along the Péru LNG and the TGP pipelines operate as geohazard prevention and leak detection systems. The solution has pinpointed several events early in advance so that preventive measures could be taken. A joint paper with the operator reporting these results will be presented at the Rio Pipeline conference.Raju Shanbhag is a contributing editor for TMCnet.
