Penetration behaviour of anchors in clay

Contact information

 

Anchors are not only used to moor ships, but are also widely used in the offshore industry to moor drilling units, production units, storage units or whatever there has to be moored. Since the offshore industry is moving to deeper waters and offshore units are getting bigger and bigger the need for case specific anchoring systems becomes more and more important. All anchoring systems are optimised for the load that will be applied on them nowadays.


Our Mission

The goal is to create a theoretical model that can determine the maximum holding capacity of a certain anchor in a given environment. The user of the program have to be able to define a certain geometrical anchor shape and the soil in which the anchor will be used. Based on these parameters the holding capacity of this anchor will be calculated.

In the model it is assumed that only conventional anchors are used. So the modeling of  drag embedment anchors, and anchors with VLA blades are beyond the scope of the model to be created.

Also only soil with clay characteristics wil be able to model; sand and rocks will not be included in the model.

The results of the model are based on calculations made in time domain. Herefore the main model is supported by four submodels:

  1. Simplification of the anchor geometry
  2. Penetration initiation of the anchor
  3. Derivation of the soil parameters
  4. Settling of the anchor in the soil
