Dry fiber augmented steel technology pipelines (FAST-Pipe™) have recently been the object of considerable attention due to both cost and availability advantages (as opposed to high strength steels) and due to their promising use in future Arctic pipeline solutions. The present paper focuses on the development and the use of a burst limit state for such fiber wrapped pipes. It describes in detail a probabilistic mechanical burst limit state model for FAST. The model is based on a large strain Cauchy stress formulation using Stewart’s isotropic strain hardening for steel pipe which is hoop-constrained by elastic fiber wrapping. The limit state model is used for a reliability comparison between FAST-Pipes and traditional pure steel pipes as well as for a risk-based equivalence between different design solutions.
