Decommissioning Analyses for Suction Caisson Foundations
Volume 9: Offshore Geotechnics; Petroleum Technology, 2023Abstract Suction caisson foundations are an economic alternative to piled foundations to support offshore jackets, especially in situations where there is shallow bedrock. Over the last few years significant advances in the design of suction caissons have developed, leading to a strong increase in installed suction caissons, particularly

Upper Bound Solutions for Uplift Ultimate Bearing Capacity of Suction Caisson Foundation
China Ocean Engineering, 2019 Suction caisson foundation derives most of their uplift resistance from passive suction developed during the pullout movement. It was observed that the passive suction generated in soil at the bottom of the caisson and the failure mode of suction caisson foundation subjecting pullout loading behaves as a reverse compression failure mechanism. The upper

Application of Suction Caisson Foundations in the Gulf of Mexico
Offshore Technology Conference, 1998Abstract In the last decade, use of suction caissons (suction piles) has increased in offshore arena. Suction caissons have the appearance of inverted buckets with sealed tops and are installed by pumping water out of them.

Long-Term Lateral Cyclic Response of Suction Caisson Foundations in Sand
Journal of Geotechnical and Geoenvironmental Engineering - ASCE, 2013 AbstractSkirted gravity base foundations and suction caisson foundations are considered as viable alternatives to monopile foundations for offshore wind turbines. While recent work has focused on the monotonic moment-rotation response for shallow foundations, the cyclic response and the accumulation of rotation over the life of the turbine must also be

A Study on the Vertical Pullout Capacity of Suction Caisson Foundation in Sandy and Clayey Soils
Lecture Notes in Civil Engineering, 2021This paper presents the vertical pullout behaviour of suction caisson foundation in clayey and sandy soils by means of finite element analysis using PLAXIS 2D under vertical static loading. The effect of caisson aspect ratio (L/D) on pullout capacity and caisson displacement was investigated under drained and undrained loading. The caisson aspect ratio

Seismic Behavior of Offshore Wind Turbine with Suction Caisson Foundation
Geo-Congress 2014 Technical Papers, 2014Offshore wind energy plays a major role in the long-term goal of relying on renewable energy. The demand for offshore wind energy is increasing rapidly in the world. However, the construction of offshore wind farm in seismic active areas has strict requirements for the foundation selection and design.

Bearing Capacity of Suction Caisson Foundations Using FEM Analysis
Advanced Materials Research, 2011To understand features of bearing capacity of suction caisson foundation is one of the key issues in design and construction of deep-water marine structures. In this paper, the general-purpose finite element analysis package ABAQUS is employed to conduct three-dimensional numerical analyses on load-carrying features of suction caisson foundation under ...

Design considerations of suction caisson foundations for offshore wind turbines in Southern China
Applied Ocean Research, 2020 Abstract Suction caisson foundations are increasingly considered as a foundation solution for offshore wind farm development in China. This paper outlines the design considerations for developing a suction caisson supported jacket solution for an offshore wind farm in Southern China. Geotechnical analyses for four major aspects, ultimate limit state (
