... is conservative if this stiffness can be demonstrated to exist. The bene- ficia/ effect of rotational foundation stiffness on the global jack-up response may lead to the conclusion that jack-up r@s are acceptable from a structural point of view, whereas disregarding it would result in rejection of the unit...

... the monitoring period. Temporary reduction of these frequencies due to increase in deck mass associated with drilling activities was detected. It is essential, therefore, to monitor the deck mass in order to distinguish the frequency variations associated with primary structural damage and foundation stiffness...

... caisson is sufficiently high in relation to the foundation stiffness to consider the interaction with the foundation to be as if the caisson was a rigid disc. The next factor to consider is the interaction between the structure and the surrounding fluid. Work by Chopra and Liaw (Ref. 1) on typical intake...
