Riser Management System
Kongsberg Oil & Gas Technologies’ Riser Management System (RMS) is a monitoring and advisory system for optimum handling of drilling and work-over risers.
The RMS gives efficient assistance in terms of continuous measurements of riser activity and responses. It covers all phases of the drilling and work-over operations from planning of riser make-up through performance of riser operations in varying environmental conditions. The usage of individual riser components can be tracked over the life time of the system.
RMS can be interfaced directly with the vessel’s DP or Position Mooring System or supplied as a stand-alone system, and gives efficient assistance in terms of continuously updated operational envelopes based on measured riser responses.
For the drilling crew, the RMS provides a number of monitoring functions including flex-joint angles, top tension and tension distribution along the riser, as well as telescopic joint stroke and connector loads.
For work-over risers, stresses and strains are monitored, typically in the tapered stress joint and the tension joint or other joints that may experience high bending moments.
