Inspection optimization of offshore jacket structures
The Profast software module is designed for planning of cost-efficient inspection of offshore jacket structures and re-qualification of existing structures. Profast can also be used for other types of structures where fatigue crack growth is considered.
Compute reliability (or the failure probability) with fatigue failure as a function of time, based on either an S-N fatigue model or a Paris-Erdogan crack growth model.
What you get with Profast software
- Reliability as function of time updated on basis of inspection findings and optionally repair
- Prescribed inspection time: for a given inspection quality, inspection and repair history, predefined inspection intervals and reliability threshold, the joints necessary to inspect are identified
- Optimized inspection time: for a given inspection quality, inspection and repair history and a predefined reliability threshold, the optimized time to next inspection is computed for a joint or a group of joints
