FPSO Turritella Integrated Marine Monitoring System (IMMS)

Requirements

We were approached with the requirement for an Integrated Marine Monitoring System (IMMS) to closely monitor the asset during pull-in, operation and disconnect. 

Multiple subsystems including environmental and facility monitoring, mooring line monitoring, and subsea acoustic monitoring of the disconnectable. We were required to allow the offshore operations personnel to operate with precise information to enhance safe working within prescribed operational limits, specifically to:

• Acquire all sensor data synchronised in time-stamped files
• Identify and alarm malfunctioning sensors and other components in the IMMS
• Display the data in form and time frame appropriate to the operational and monitoring requirements
• Provide user friendly displays of operationally important information
• Archive the measured data 

Solutions

Our Integrated Marine Monitoring System (IMMS) provided real-time information of the environmental conditions and motions experienced on the FPSO as well as the buoyant turret mooring position and line monitoring during pull-in, operation and buoy release. 

The project involved the world’s deepest moored producing FPSO facility and the first use of Steel Lazy-Wave Risers (SLWR) with a disconnectable FPSO in a harsh environment. 

Benefits

• Our integrity monitoring systems allow offshore operations personnel greater access to information to enable them to work safely by making informed decisions.
• We have designed and manufactured more than 120 life-of-field IMMS for multiple floating production asset types worldwide (including Semi-subs, Spars, TLPs, FPSOs, SPM buoys) and continues to provide preventative servicing and maintenance for these systems today.
