... to meet that challenge. Retrofitting strain sensors to subsea structural members presents many technical challenges, as neither conventional strain gauges nor cabled connections are feasible in the harsh subsea environment. For the first deployment, the instrumentation required robust attachment to a 1.2...

... code and functional requirements, several strain gauges, and Linear Variable Differential Transformers (LVDTs) are used to monitor data under various load cases to give confidence that this critical component of the subsea connector system is within ASME code and functional requirements. A good...

... Abstract In this paper, a general method is presented which combines strain gauges’ data with 3D Finite Elements analysis of a hull structure, allowing the complete reconstruction of the structural response everywhere in the structure, based on the measurements from only a few sensors...

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...
