7          Conclusions

In spite of the abnormal large dimensions of the caisson it appears to be possible to moor such a caisson. In this report describes a mooring system design consisting out of 38 synthetic lines, which are suspended taut in a nearly radiated pattern from a turret in the centre of the caisson in order to allow it to weathervane. The mooring lines are attached to the seabed by means of suction piles, because of the fact that they need to handle vertical forces.

 

To meet the very flexible operational demands is an very difficult question; a caisson like this cannot be moored and at the same time be as flexible in use such that it can be moved form one location to another between water depths of 150 and 45 meter.
