Column type load cell
Benefits of an In-line System:
• Reduced top connector stack-up height• Sensor system not in tendon load path• Potentially can be retrofitted to existing
tendons• Sensor can be made to be diver or ROV
serviceable/replaceable
Benefits of a Porch Based System:
• Fully installed and tested in dry dock• Immediately ready to use for installation• Design can permit load cell replacement
submerged with ROV/Divers and to retain correct “ZERO”
• Robust cabling embedded in protected structure

TTMS Features:
• Acquire all sensor data synchronized in time stamped files
• Identify and alarm malfunctioning sensors and other system components
• Display the data in a form and time frame appropriate to the operational requirements
• Provide user friendly displays of operationally important information
• Reliably archive the measured data
• Data access from multiple locations on-board the TLP as well as shore based computers via networks or other data links
• Interfaces to platform control systems via a number of protocols
• Shunt calibration of load cells available.
