Geotechnical Analysis of a Unique Spudcan-Pile Combined Foundation System
Geotechnical Analysis of a Unique Spudcan-Pile Combined Foundation System
A major offshore accommodation platform, constructed in the 1970s in the Middle East, is supported by a unique spudcan-pile foundation system that integrates a spudcan with a drilled and grouted pile in calcareous rock at each platform leg. This combined spudcan-pile foundation system is rare with limited (if any) prior studies reported in the literature. The original design conservatively excluded the contribution from spudcan. However, to meet the design criteria for extending the platform's operational life, it is necessary to account for the contribution of the spudcan. To assess the resistance provided by both the spudcan and the pile, a three-dimensional finite element analysis is conducted. This analysis examines the soil-structure interaction of this unique spudcan-pile system, and the load distribution between the spudcan and the pile. Additionally, the ultimate axial geotechnical capacity of the combined spudcan-pile foundation system is estimated.
