RISHybrid Subsea Foundations for Subsea Equipment
Publisher: American Society of Civil Engineers
Abstract: A hybrid subsea foundation (HSF) is defined here as the combination of shallow and deep foundations, designed such that both shallow and deep foundation elements contribute to the total foundation capacity. In this project ...
Experiments Using a Novel Penetrometer to Assess Changing Strength of Clay during Remolding and Reconsolidation
Publisher: American Society of Civil Engineers
Experimental Investigation of Installation and Pullout of Dynamically Penetrating Anchors in Clay and Silt
Publisher: American Society of Civil Engineers
Abstract: This paper reports the results from a series of model tests undertaken to provide insight into the behavior of torpedo anchors during dynamic installation and pullout in lightly overconsolidated kaolin clay and calcareous ...
Improving Plate Anchor Design with a Keying Flap
Publisher: American Society of Civil Engineers
Abstract: Suction embedded plate anchors have been increasingly applied in deepwater projects because of their efficiency and limited cost. Current industry practice equips the fluke of the anchor with an outwardly rotating keying ...
Accounting for Soil Spatial Variability in Plate Anchor Design
Publisher: ASCE
Abstract: The effect of soil spatial variability on the undrained vertical uplift capacity of plate anchors has been examined using the three-dimensional random finite-element approach. Multiple direct Monte Carlo simulations (MCS) ...
Evaluating Uncertainty Associated with Engineering Judgement in Predicting the Lateral Response of Conductors
Publisher: ASCE
Abstract: This paper presents the results from a prediction event, organized by the University of Western Australia (UWA) and the National Geotechnical Centrifuge Facility (NGCF), and performed as part of the International Symposium ...
Investigations into the Uplift of Skirted Foundations on Clay at Varying Rates
Publisher: ASCE
Abstract: This paper presents finite-element simulations to reinterpret a series of full-model and particle image velocimetry (PIV) (half model) centrifuge tests to study the uplift of skirted foundations. The focus is on the influence ...
Considerations on the Design of Keying Flap of Plate Anchors
Publisher: American Society of Civil Engineers
Abstract: One of the critical issues associated with plate anchor performance and design relates to the reduction of the loss of embedment during the keying process. As deep water offshore sediments typically exhibit an increasing ...
Incorporating Shank Resistance into Prediction of the Keying Behavior of Suction Embedded Plate Anchors
Publisher: American Society of Civil Engineers
Abstract: The suction embedded plate anchor (SEPLA) is a promising deepwater anchoring solution that uses a suction caisson to install a plate anchor vertically to a precise depth within the seabed. The plate anchor is then rotated ...
Experimental Investigation of the Effect of Cyclic Loading on Spudcan Extraction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Selfelevating mobile jackup units have been employed in offshore exploration and development in shallow waters at depths of up to approximately 150 m. Jackups are designed to move to a new site after operations are ...
