GARDEN BANKS 388 DEEPWATER PRODUCTION RISER STRUCTURAL AND ENVIRONMENTAL MONITORING SYSTEM

A deepwater production riser installed in Garden Banks 388 in the Gulf of Mexico has been instrumented with bonded resistance strain gauges so that the remaining operational fatigue life can be quantified. The distribution of bending stresses throughout the riser, which is attached to a template at 2096 foot depth and extends to within 150 feet of the surface, reaches a maximum at the bottom. The riser is instrumented with strain gauges, inclinometers, and accelerometers at five locations along its length so that tension, bending, orientation, and motion of the riser can be monitored at these locations, including the bottom joint. Correlation of the riser response data with excitation or environmental data, including wave motion, current velocities, wind velocities, and vessel mooring tensions and positions is enhanced by acquiring and archiving all data on a single common system having multiple redundant elements for reliability. This paper describes the production riser structural and environmental monitoring system used on the Garden Banks 388 project.
