... pressure up to 25,000 psi, with application of 5,000-psi external pressure simulating 10,000-ft applications. The valve block was strain gauged at multiple locations including the body and the bolts. The strains predicted using the finite element analysis (FEA) methods are then compared to the strains...

... 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 used...

... application. In addition, a 300mm high boulder bend was applied to the pipeline at pressure and temperature to verify that the compressive loads are too low for buckling to occur. The applied loads and the bundle PIP responses have been monitored in real-time using fibre optics and strain gauges...

... 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...

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 were equipped with strain gauges. Both the wave induced motions...
