Minimize recertification downtime while maintaining required reliability level.
Our method is based on solid engineering experience combined with utilisation of sophisticated Finite Element analyses. The following elements are considered:
- History of the rig (operating history and
modifications)
- Inspection history of welds
- Global analyses and local Finite Element
analyses of fatigue sensitive details
- Inspection programme for next Class period
The method is known as SIMP™ (Structural inspection and maintenance programme).
Calculation of SCF (Stress Concentration Factor) applying hot-spot method. Patran has been used to model the FEM (Finite Element Model), applying SESAM for the mathematical solution. From the Bredford Dolphin platform.
