Defining a Seabed

Previous page Next page

Firstly, you need to create a Seabed component to specify the characteristics of the seabed at a particular location. This component will be referenced subsequently by the Model component is order to characterise the seabed topography. To create a Seabed component in the Model folder, right-click and select New > Model > Seabed. Rename this new component Rigid Seabed.

PipeLay has both rigid and elastic seabed models. Seabeds of both types may be either flat sloping, or completely arbitrary in profile. Elastic seabed stiffness may be either linear or non-linear. The elastic seabed algorithm also includes a suction force model. Seabeds of either type may be smooth or have longitudinal, transverse or torsional friction included.

When you create a new Seabed component, the default specification is that of a smooth flat rigid seabed. For Example 3, the default specification is already sufficient and you may ignore all inputs on the Seabed component.

The Component View for the Seabed component is as shown in the figure below.

Back to Creating the Model Overview

The next step in creating a model is to add a model by creating a Model component. This is described in the 'Adding a Model' article.
