... ABSTRACT This article presents a framework for a consistent, rigorous, and super-fast suction caisson design. By considering cyclic loading effects and implementing all relevant geotechnical design tasks in a semi-automatic design tool, a wide range of different site and soil conditions can...

... anchored to the seabed by means of suction caissons. To facilitate installation, a single pinned connection is implemented at the tower base, which is founded on a circular shallow footing. By eliminating the moment transfer at the tower foundation, the system's design requirements are substantially...

... ABSTRACT Suction caissons are frequently used on a variety of offshore structures and at present they are considered as a foundation for floating wind turbines. However, no systematic study on floating wind turbine foundations is reported for the northern region of South China Sea. To bridge...

... factors were also concluded in this paper. INTRODUCTION Suction caisson is a large, hollow, cylindrical steel or concrete structure which resembles upturned buckets. It is also known as suction anchor, suction pile, or bucket foundation. The principle of the suction caisson technique is to generate...

... Abstract Excessive soil plug heave that occurs during installation plays an important role in successful installation of suction caisson. However, the mechanism of sand heave has not been fully investigated. In this study, model tests were performed to investigate the mechanism of sand heave...

The aspect ratio of the caisson (L/d), the undrained shear strength of the clay soil in which the caisson is installed (S u ), the relative depth of the lug to which...

... Abstract Suction caissons are widely used in mooring systems for deep water oil and gas development projects. The response of a caisson in sand is different from its response in clay under pullout force. In this study, three-dimensional finite element (FE) analyses are conducted to calculate...

... ABSTRACT Suction caissons are a foundation system, most commonly used in the offshore petroleum industry, and also considered applicable as a foundation for offshore wind turbines. Due to relative thin wall thickness compared to the caisson diameter, buckling of the cylindrical caisson during...
