... to occur. The applied loads and the bundle PIP responses have been monitored in real-time using fibre optics and strain gauges for verification, in the presence of a third party. The test results were successful and are presented and discussed herein. It has been found that the monitoring solution can...

... and a full-scale test was performed on a portion of the jumper (quarter jumper). A test fixture for the full size quarter-jumper pull test was modified to ensure enough stroke was available to fail the jumper sample in a single, continuous pull. Strain gauges, a data acquisition system, and video system were...

... to the Wellhead, thus allowing for direct measurements of the bending moments and axial forces. Statoil has been able to measure strains close to the WH on 3 different drilling MODUs. In one case this was accomplished by using strain gauges directly on a spool piece below the BOP stack, in a second case...

... behaviour are considered. Calculated strains are presented alongside strain gauge measurements taken from the sample, and fatigue lives derived using DNV-RP-C203 are compared against the actual numbers of cycles for tube through wall-thickness cracks to develop.

This is usually done through structural modeling and either spot monitoring campaigns using MEMS accelerometers or through subsea conventional strain gauges. Both technics present weaknesses: MEMS sensors usually require a great deal of data processing...

... by the University of Miami. The composite pipe was 485.3 feet long and 1.4 inches in diameter. The pipe was instrumented with fiber optic strain gauges to monitor the vibration. The pipe was spooled on a drum that was mounted on the aft portion of the boat. The pipe was un-spooled and lowered into the water using...

.... The objective of the instrumentation was to measure sufficient signals to derive the fatigue loading on the vessel. The dedicated monitoring system comprised the instrumentation of two cross sections of the vessel with strain gauges, pressure transducers and wave height radar s. Also the deck and the turret...
