ABERDEEN, UK --FMC Technologies has contracted Fugro GEOS' Structural Monitoring Division to supply a riser management system for a completion/workover riser for Statoil's Gjøa field offshore Norway.
The RMS consists of riser-mounted instrumentation, cables, and computer system running the MCS software. IRIS-RMS interfaces with vessel systems to collect data for the software's finite element predictive model and associated simulation software. Riser-mounted strain and/or accelerometer packages typically are installed. The system also includes modules to calculate and display the operating envelope and drift-off characteristics.
The system monitors and records riser loads during operation and also displays hot-spot stresses within the riser and computes the top tension and tensioner/hook load tension split. It tracks the fatigue life of each joint in the riser, and records and displays riser stresses during unexpected/unplanned incidents. IRIS-RMS warns if the riser is approaching its design capacity.
