Riser management contract for Fugro
Posted: 6 July 2007
Fugro GEOS' Structural Monitoring Division has recently been awarded a contract by FMC Technologies to supply a Riser Management System (RMS) for a completion/workover (C/WO) riser that FMC Technologies is supplying for Statoil’s Gjøa field, offshore Norway.
Developed by Fugro and MCS, the market leaders in riser analysis and associated software the IRIS-RMS system is an integrated riser management system for drilling and C/WO risers that calculates a safe operating envelope using the unique MCS finite-element model of the riser.
The RMS consists of riser-mounted instrumentation, cables, and computer system running the MCS software. IRIS-RMS interfaces with vessel systems to collect key data to feed into the software’s sophisticated finite element predictive model and associated simulation software.
Riser-mounted strain and/or accelerometer packages are also typically installed. The system also includes modules to calculate and display the operating envelope and drift-off characteristics.
Not only does the system monitor and record riser loads during operation, it also displays hot-spot stresses within the riser and computes the top tension and tensioner/hook load tension split.
It also 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.
