Current and Future Developments in Offshore Platform Foundations
The first section of this paper reviews the historical development of platform foundations in the North Sea and the various methods of incorporating the foundations into the structural platform analysis. The second section concerns some of the more recent or unusual foundation concepts, including suction can foundations, compound gravity/jackup plutjiorms, and the semi-permanent use ofjackups. The third section considers the developments needed to ensure that efective foundation solutions can be obtained worldwide, in a range of soil conditions and in deep water and highlights some of the geotechnical challenges associated with such developments. The final section discusses the importance of current changes in offshore Code requirements and their applicability - or otherwise - to current field development areas.
