Site-wide automated sizing of suction caisson foundations
Site-wide automated sizing of suction caisson foundations
Suction caisson foundations are a shallow to intermediate foundation type characterised by the use of suction pumps to install the foundation as opposed to, for instance, use of impact driving. This paper presents a framework for automated sizing of suction caisson foundations used in combination with a jacket substructure, focusing on the integration of installation feasibility and in-place capacity assessments within a unified design workflow, including automated soil profiling, which allows for an accurate assessment of requirements for each foundation. Key design checks and methodology for performing them are introduced and used to determine the most optimal diameter and embedment. By optimising foundation dimensions through a two-stage approach - initial optimisation for individual locations followed by collective optimisation across the wind farm, depending on clustering considerations and synergies, the proposed framework enhances efficiency and cost-effectiveness in the design and development of offshore wind farms using suction caisson jacket foundations.
