Adjustments were made regarding water depth, incoming
waves and modeling of the skirt.
The water depth for the model was limited to 100 m. Experiments
and common practice show that this water
depth is sufficient to neglect the effects of the seafloor
on the wave-boom model, as further explained in Figure
3.49. Water depths for the chosen locations are in the order
of kilometers and would have significantly increased
computation time. Also, the length of the boom in the
model was not the full 100 km. Instead several simulations
with booms ranging from about 0.5 to 2 km in length
were done to be able to extrapolate the forces to longer
booms.
For further modeling time reduction, a combination of
significant wave height (Hs) and wave period (TZ) was chosen
rather than assessing the performance for the full
range of sea states. The definitions of these parameters
can be seen in Figure 3.50. More elaboration on this can
be found in the section 3.5.2.1. Here, the full series of
measured sea states is presented in the form of a wave
scatter diagram.
