Abstract:
A floating structure 1, for instance a semi submersible platform, comprises a deck structure 2, vertical columns 3 and a pontoon structure 4. The floating structure 1 is moored to the seabed with anchor lines 7. The floating structure is moored with taut line anchoring system, and the vertical stiffness in the anchoring system is approximately 20% of the water plane stiffness for the floating structure. The pontoon structure 4 comprises at least two levels of pontoons and the columns 3 are formed to give variable water plane stiffness.
