2.1 / ASTM WK43991: STANDARD PRACTICE FOR THE INSTALLATION OF OPTICAL FIBER CABLES ALONG PIPELINES FOR LEAK DETECTION USING DISTRIBUTED VIBRATION, STRAIN, AND THERMAL SENSING

Table 2 enumerates the working groups and initiatives actively involved in developing new standards that target the intricacies of distributed fiber sensing, including a focus on specialized Brillouin sensing. Participation in these working groups is strongly recommended. Notably relevant standards are emphasized in bold, and their respective descriptions are provided subsequently.

Table 2. Standards in development relevant for the distributed sensing equipment and measurements

§  ASTM WK43991

Standard practice for the installation of optical fiber cables along pipelines for leak detection using distributed vibration, strain, and thermal sensing Proposed Scope: This standard will reduce pipeline and construction industry uncertainty on the selection and use of proper materials, locations, and methods for the installation of optical fiber cables along pipelines for the purpose of leak detection and localization. This standard will provide the information needed for best-practice on design and installation techniques to support leak
detection using vibration, strain, and thermal sensing with optical fiber cables near pipelines.

§  ASTM WK46887

Standard practice for the use of fiber optic distributed temperature sensing to detect leaks in above-ground ammonia, ethylene and LNG pipelines Proposed Scope: This standard will publish best practices on the selection and use of proper materials, locations, and methods for the installation, operation and maintenance of optical fiber cables for above ground pipelines transporting ammonia, ethylene, LNG and similar fluids for  the purpose of leak detection using distributed temperature sensing (DTS).

§  SEAFOM MSP037

Measuring Sensor Performance This initiative is aiming to provide guidelines to aid system integrators ability to comparatively choose the best suitable distributed strain instrument needed for job/installation as well as Facilitate operator / end user to specify a minimum performance levels of strain monitoring technology for given application. The scope is limited to the testing of an instrument in conjunction with a selected fiber only. The document is including such items as definitions and testing methods for repeatability and spatial resolution; different test methods for long range vs. moderate range/high spatial resolution applications.
