This PhD work will develop an innovative approach to improve current reliability assessment of jacket platform by incorporating new information using Bayesian methods.
Fatigue failure is an important issue in offshore platforms. In order to maintain safety of jacket platforms in service life with respect to fatigue, inspection is an important measure. The inspection and repair program is crucial to improve fatigue performance and also to extend the service life of offshore structures. However, significant cost of inspections, particularly underwater inspections, make it important to properly prioritise inspection locations and inspection frequency.
Where offshore platforms are inspected to assess the state of damage resulting in information such as detection and measurement of cracks, such information can be used to update the probability distributions of uncertainties.
