Cryogenic DTS Application

LNG Carrier: Monitoring of the Integrity of Membrane Containment Systems

Cologne/Germany — LIOS Technology distributed temperature measurement system (DTS-System) is suited ideally to detect reliably and to locate precisely any temperature anomaly caused by an accidental release of Liquid Natural Gas (LNG).

Their innovative and patented Optical Frequency Domain Reflection (OFDR) evaluation method enables the determination of a continuous temperature profile along the entire length of an optical fibre offering thousand of data points at a single measurement.

Based on expert knowledge and an impressive record of safety installations they have developed suitable alarm processing algorithm to detect temperature events fast, reliably and precisely.

Also multiple temperature events are identified and pinpointed simultaneously allowing the operator to initiate proper counter measures rapidly.

With the capability to use multiple optical channels and a measurement range of several kilometres per channel the LIOS Technology DTS system is a cost-sensitive solution for an entire cryogenic supervision including containments, foundations, pumps and piping.

The system supplies precise temperature information which facilitates the control of cool-down operations like load- and unload procedures. Additionally, an optional loop set-up of the sensor cable enables a redundant operation of the system.

Consequently, the entire measurement length keeps maintained in case of single fibre break. Summarized the operator takes the following benefit from using LIOS Technology DTS system:

* Full information of containment integrity ??? everywhere at any time
* Significantly reduced off-times due to exact pinpointing of leaks
* Enabling effective and automatic counter measures
* Fast detection of slow leaks as well as sudden leaks
* Better control of load and unload procedures (cool-down operations)
* Maximum safety of people, assets and environment
* Redundant operation thanks to loop set-up of the sensor cable
* Reduced installation efforts ??? additional wiring is not required
* Low maintenance efforts and cost
* Long lifetime
