The purpose of monitoring the FPSO hull is to schedule timely interval inspection of what happens to the structure of the hull and then be able to make plans as to when and what to do when the gradually degrading condition approaches a stage at which the level of risk or the degree of unreliability become unacceptable.

The monitoring usually followed by systematically recording the rate of change within which degradation of the structure could have serious effects on the future safe operations of the structure and/or would be difficult and expensive to repair.

The monitoring and inspection plans can be achieved by:

  • Visual Inspection (crack, corrosion, pitting, coating, etc.)
  • Equipment Based Monitor (close circuit television systems recording, ultrasonic thickness meters, humidity meters)

Analysis of history information can also help to identify the monitoring purposes.
