Reliably assessing the structural integrity of flexible pipe
The structure of flexible risers is too complex for conventional inspection technologies to be effective. MAPS-FR adopts a unique approach to overcome these challenges, employing GE’s patented MAPS® magnetic stress measurement methodology to sense the actual stress levels in the load bearing steel wires. From this information the integrity of the armour wire layers may assessed. A key benefit of MAPS-FR is the concept of ‘reach’, the ability to sense the effect of a wire break many meters away from the actual damage site. This is of particular advantage in assessing integrity in and near the splash zone and up to the top termination where there is no access to the pipe. Coupled with the ability to provide information wire-by-wire and layer-by-layer, this allows the system to take the integrity assessment of flexible pipe to a new level.
