Fibre optic distributed sensing for dynamic strain monitoring applications

  Peru - Pipeline integrity monitoring

The operators of a liquid natural gas (LNG) pipeline comprising a new 408 kilometre (km), high-pressure gas pipeline system required a long-range monitoring system. The route runs over the Peruvian Andes to a new LNG facility constructed approximately 170 km south of Lima on the coast of Peru.

  Alaska - Offshore pipeline integrity Oooguruck

Flow assurance and pipeline integrity on 14 km offshore pipeline - Given arctic harsh conditions, monitoring the integrity of an offshore flowline bundle was vital to minimize impact to the fragile Arctic environment as well as risks associated with leakages and flow down-time.

OMNISENS - the Swiss designer, manufacturer and supplier of fiber optic sensing systems for the oil, gas and energy industries has appointed Keith Grimes as Chairman and Bob Buskie as CEO to help drive business growth.

OMNISENS received the FROST & SULLIVAN 2008 Global Fiber Optic Sensors Customer Value Innovation of the Year Award for its DITEST product range and solutions.

The DITEST STA-R is the latest and revolutionary fiber optic distributed sensing system developed by the Swiss company Omnisens. It features simultaneous and accurate temperature and strain measurements over tens of kilometers using standard single-mode optical fiber, providing thousands of monitored locations with a single fiber optic sensing cable.

Omnisens, the worldwide known company in fiber optic temperature and strain sensing, is pleased to introduce Dana DuToit as Omnisens new North America Manager.

The DITEST STA-R is the latest model of Fiber Optic Brillouin-based sensing technique pioneered by Omnisens

Omnisens SA, a technology pioneer and world leader in long-distance distributed fiber-optic sensing announced today that it has raised CHF 6 million from the Private Equity investor Vinci Capital in Lausanne, via the funds Renaissance Technologies 2 and Mona Lisa. The founders of the company Marc Niklès (CEO) and André Bals (COO) stated “this new funding will allow us to continue developing our unique monitoring solutions and give us the resources to intensify the sales and marketing efforts on the rapidly growing market opportunities in the Oil and Gas industry”.

OMNISENS DITEST Solutions offer complete pipeline monitoring with required sensitivity for pipeline leak, pipeline intrusion or ground movement detection.

Multiple channel extension module for fiber optic distributed monitoring systems

Omnisens DITEST-SHM distributed strain analyzer now features enhanced signal processing algorithms in order to detect highly localized strain contributions along fiber optic sensors associated to the development of cracks in structures. The crack detection is performed automatically within the spatial resolution of the instrument (0.5m) and cracks in the millimeter range can be efficiently detected.

Offshore arctic conditions pose unique design challenges to the safe operation of subsea pipelines. The pipeline route may be exposed to seabed ice gouging and permafrost thaw settlement. If the pipeline route is located near the mouth of a river, it may become exposed due to seabed erosion from springtime river overflood draining through holes in the ice sheet (strudel scours) or river channel flows. In some areas, the seabed may have migrating bedforms or the pipeline may be subject to upheaval buckling. These arctic conditions can apply significant loads on a subsea pipeline or leave it exposed above the seabed to other applied loads.

Omnisens DITEST-LTM monitoring system successfully used to perform sub-sea pipeline temperature monitoring and flow assurance in the Oooguruk oil Field offshore in Alaska

The paper describes the possibility to map the evolution of the beat length in an optical fiber using stumlated Brillouin scattering and its application to distributed PMD measurements.

As fiber optic distributed scattering sensing systems are providing innovative solutions for the monitoring of large structures, the comparison of the different techniques and solutions is difficult because of the lack of standardized specifications and the difficulty associated to the characterization of such systems. The article presents a tentative definition of performance specifications and qualification procedures applicable to fiber optic distributed sensing systems aiming at providing clear guidelines for their design, specifications, qualification, application and selection.

Omnisens actively participates to SEAFOM "Measuring Sensor Performance" working group aiming at establishing consistent terminology relating to performance claims of sensors to facilitate comparison.

The monitoring of temperature profiles over long distance by means of optical fibers represents a highly efficient way to perform leakage detection along pipelines, in dams, dykes, or tanks…

Omnisens was selected for the development and the installation of the DITEST-LTM system for the detection of leakage along the 55km brine pipeline in Berlin-Germany
