INTEGRATION OF MONITORING SYSTEMS
Fulfilling increased safety demands in integration of sub-systems
is becoming more common with modern FPSO, FLNG and
FSRU
Integration is of load monitoring systems, remote release,
environmental and reporting
Integrated systems provide:
Common operator workstation to display, monitor and report
Common portable display units for all sub-systems
Efficient sharing of information between sub-systems
Information can be easily shared with third party systems i.e. DCS
Smarter site cabling
Shared hydraulic system (ie hose and hawser reel)
Substantial cost / performance benefits
There is a single point responsibility for complete system design,
manufacturing, commissioning, warranty and training
