Seabed Modelling in Frequency Domain Analysis

Previous pageNext page

This section discusses how seabed contact is modelled in frequency domain analyses. If you are analysing an SCR or a flexible riser (e.g. a free hanging, lazy S or lazy wave configuration) in the frequency domain, an important consideration is how the program models the interaction between with the riser and the seabed. There are two aspects to this issue, namely:

(i)Riser motion in the direction normal to the seabed.

(ii)Riser motion tangential to the seabed.
