  • Suction Caissons
    1 Comprehensive Status Report: November 18, 2004 OTRC Project Title: Suction Caissons & Vertically Loaded Anchors MMS Project 362 TO 16169 Project Subtitle: Suction Caissons: Seafloor Characterization for Deepwater Foundation Systems PI: Robert B. Gilbert MMS COTR: A. Konczvald This report provides a comprehensive summary of the research completed in all prior Phases of this project (September 1999 – August 2004), and describes research being done in the present Phase (September 2004 – August 2005) to complete this project. Note that this report addresses one of four related research areas on this project. The other three areas are reported separately under the subtitles – Suction Caissons: Model Tests, Suction Caissons: Finite Element Modeling, and Suction Caissons & Vertically Loaded Anchors: Design Analysis Methods. Suction Caissons: Seafloor Characterization for Deepwater Foundation Systems Robert B. Gilbert and Shadi S. Najjar (Graduate Research Assistant) INTRODUCTION The challenge of seafloor characterization for deepwater facilities is that the mooring foundations, subsea well trees and flowlines are spread over large areas (tens of thousands of feet across), while the cost of obtaining high-quality geotechnical data for the seafloor is high. Therefore, information from a handful of soil borings is typically extrapolated over thousands of feet to design foundations. This extrapolation leads to uncertainty that could potentially lead to excessively conservative designs or to unreliable designs. The goal of this research is to develop a reliability-based methodology to design offshore foundations with limited seafloor characterization data and to apply this methodology to optimize geotechnical investigation programs. Specific research objectives are: 1. Develop models describing spatial variability in foundation design parameters for different geologic profiles encountered in deepwater fields.

Suction foundations, traditionally used as anchors and jacket foundations in the oil and gas industry, are now also used in the offshore renewable (wind) industry, e.g. for monopods, tripods, and jackets. When technically feasible, suction foundations are often cheaper than pile foundations. Ad- ditionally, their installation is relatively noise-free and, by applying overpressure, they can be removed during decommissioning. This paper focuses on the more complex design issues and some pitfalls related to suction foundation design. Additionally design practices and recommendations for suction caisson design, including installation and extraction feasibility, foundation resistance, settlements and response in sand, clay and layered soil profiles, will be presented for basic understanding. Key words: Suction foundation; Caisson; Anchor; Bucket; Installation; Resistance, Capacity; Extraction https://doi.org/10.1631/jzus.A1700465 CLC number: TU47 1 Introduction installation depth (m) and D is the caisson diameter (m).

While shallow foundations rely solely on the bearing capacity of the soil beneath them, deep foundations can rely on end bearing resistance, frictional resistance along their length, or both in developing the required capacity. As offshore developments move into deeper waters, gravity based structures become less economical due to the large required size and cost of transportation. Kolk H. Views Read Edit View history.

Until the 18th century, however, no theoretical basis for soil design had been developed and the discipline was more of an art than a science, relying on past experience. Fugro offers a wide range of services associated with the design of offshore structures. A slope failing as flow would resemble a fluid flowing downhill. It is typically carried out in order to explore for and subsequently extract petroleum which lies in rock formations beneath the seabed.

    Proceedings of the 18th International Conference on Soil Mechanics and Geotechnical Engineering, Paris 2013 McClelland Lecturelecture Analytical contributions to offshore geotechnical engineering Conférence McClelland Contributions des méthodes analytiques à la géotechnique offshore Randolph M. F. Centre for Offshore Foundation Systems, University of Western Australia ABSTRACT: The theme of this paper, the written version of the 2nd McClelland Lecture, is the contribution of analysis to offshore geotechnical engineering. The application areas considered range from the axial and lateral response of piles, to seabed infrastructure associated with deep water applications, including shallow skirted foundations, anchors, pipelines and risers. The emphasis throughout is on analytical solutions, including appropriately framed outcomes of numerical studies. Most of the material is retrospective, summarising key contributions in an effort to facilitate access, and thus help close the gap between theory and practice. RÉSUMÉ : L’objet de cet article, la 2e conférence McClelland, est de présenter les contributions des méthodes analytiques à la géotechnique offshore. Il couvre plusieurs champs d’application, de la capacité axiale et horizontale des pieux au comportement des structures géotechniques associées aux développements en eaux profondes, incluant notamment les fondations superficielles avec jupe, les systèmes d’ancrages et les pipelines. L’accent est notamment porté sur les solutions analytiques, dont certaines sont basées sur des résultats
