| Description |
The purpose of this
project was to use existing data to
develop a model to evaluate aging offshore platforms. The factors considered in the model
included realistic loading, performance, inspection and repair costs. A case study of
selected older platforms were used to validate the model. Initially, an assessment was made of total system safety on these platforms. Next, an optimized decision model for
extended platform life will be developed. The optimized model considered environmental
and operational safety/production benefit analysis; inspection scheduling; repair and
failure costs. The findings and recommendations of the study are expected to provide
benchmarks on environmental and operational safety for older offshore platforms. |
