DETERIORATION MODELS DEVELOPMENT METHOD FOR OFFSHORE JACKET-TYPE PLATFORMS
Methods of determining an offshore jacket platform’s condition including determining a geometry, a plurality of loads, and a material composition of an offshore jacket platform; obtaining a base shear at collapse when the offshore jacket platform is intact; calculating a residual resistance factor; determining a criticality factor for each of a plurality of members on the offshore jacket platform; determining a structural health condition state; determining the probability of deterioration; and modeling a rate of deterioration. Another aspect of the disclosure includes methods of determining an offshore jacket platform’s condition in case of lack of inspection records including selecting a corrosion wastage model for splash zones and immersion zones, identifying distribution parameters for the legs and bracings of the jacket platform; determining a structural health condition state for leg and bracing; aggregating probable structural health condition states; and modeling a rate of deterioration of the offshore jacket platform.
