Numerical implementation of the installation/mooring line and application to analyzing comprehensive anchor behaviors
TL;DR: In this article, a large deformation finite element (FE) analysis employing the coupled Eulerian-Lagrangian technique is performed to simulate the installation/mooring line, and then is applied to analyzing comprehensive anchor behaviors in the seabed.

On the instability of offshore foundations: theory and mechanism
TL;DR: In this paper, the authors focus on the foundation instability and its failure mechanisms as well as the relevant theory advances for the prevailing foundation types in both shallow and deep water depths, including piles, spudcans, gravity bases, suction caissons, and plate anchors.
Journal ArticleDOI
A novel kinematic model for drag anchors in seabed soils
TL;DR: Based on a kinematic model and mathematical derivations, a theoretical framework for predicting the trajectory of drag anchors is established in this paper, which can provide a new angle of view to understand the anchor behaviors in seabed soils.
Journal ArticleDOI
An efficient approach to incorporate anchor line effects into the coupled Eulerian–Lagrangian analysis of comprehensive anchor behaviors
TL;DR: Based on the coupled Eulerian-Lagrangian (CEL) method, a numerical approach incorporating anchor line effects is developed to investigate comprehensive anchor behaviors in the soil, including penetration of drag anchors, keying of suction embedded plate anchors and diving of gravity installed anchors as discussed by the authors.

Profile and frictional capacity of embedded anchor chains
S.R. Neubecker,Mark Randolph +1 more
TL;DR: In this article, closed-form expressions for both the load development and chain profile have been derived, which greatly simplify the procedure for estimating the load and inclination of an embedded chain at some connection point in the soil.

Drag anchor fluke-soil interaction in clays
TL;DR: In this paper, the interaction between anchor flukes and undrained soil at failure was investigated using finite element analysis, and the behavior of a rectangular and a wedge-shaped anchor was investigated.
Drag anchor fluke-soil interaction in clays
Mark Fraser Bransby,M.P. O'Neill +1 more
TL;DR: In this article, a fine element analysis has been used to investigate the interaction between anchor flukes and undrained soil at failure and the results have been presented in terms of a plasticity framework to produce an associated plastic failure locus for combined loading conditions.

Soil resistances to embedded anchor chain in soft clay
Gijs Degenkamp,Amit Dutta +1 more
TL;DR: In this paper, the authors present a method to calculate the chain tension at the anchor point and the chain configuration inside the soil for an anchoring system consisting of a pile with an embedded connection between the anchor pile and the mooring chain.
