Description This paper describes an experimental investigation carried out involving instrumentation, measurement and monitoring of stresses in a large diameter gas pipeline during its lowering operations. It also highlights the ingenious techniques developed and adopted to overcome the dificulties pertaining to long leadwires, measurement of existing strains on the curved su$ace of a pipeline and protection of strain gauge installations. These novel methods were used to ensure smooth and properfunctioning of strain gauge instrumentation even under the severe field conditions at site for more than two weeks, till the lowering operations and pipeline monitoring was successfully completed.
