Abstract

This thesis proposes a novel dynamically installed fish anchor, adopting a geometry taken from nature, for economic and safer tethering of floating facilities in deep water with calcareous sediments. The fish anchor embedment depth during dynamic installation, and capacity under both monotonic and cyclic operational loading in calcareous silt were assessed through centrifuge model tests. In parallel, the thesis has developed a numerical model for effective stress analysis capturing the evolution of pore pressure induced by dynamic installation of anchors. The advanced elasto-viscoplastic modified Cam clay soil model was incorporated to account for the strain rate effect.
