Evaluation of probabilistic models

Probabilistic model evaluation of jacket foundations for offshore wind turbines

Studying potential failure modes and preventing their occurrence

Offshore structures are designed to withstand loads and this capacity must exist throughout their lifetime. Therefore, it is necessary to study potential failure modes and prevent their occurrence. However, there are large uncertainties associated with offshore structures. Uncertainties in structures are considered through probabilistic models.

In this project, an assessment of the fatigue life of offshore jacket joints is carried out using probabilistic models. Thus, the probability of joint failure due to fatigue over time is calculated and inspections are defined to meet the maximum acceptable failure probability. This analysis is developed in accordance with DNVGL-RP-C210 – Probabilistic methods for planning of inspection for fatigue cracks in offshore structures.
