12. INTEGRATION OF MONITORING SYSTEMS
Integration of sub-systems is
common in modern FPSO
(Load Monitoring Systems,
Remote Release, Mooring
and Docking, Environmental
and Reporting)
Integrated system design
implemented by Trelleborg is
based on proven techniques
and interface methodologies

13. INTEGRATION OF MONITORING SYSTEMS
Main advantages of
integrated systems are:
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
Substantial cost / performance benefits
Single point responsibility for
complete system design,
manufacturing,
commissioning, warranty and
training
