... ABSTRACT Behaviors of the plate anchor during its service life is a typical soil-pore water coupled problem. In this paper, the long-term performance of the plate anchor and cyclic pull-out using coupled analysis were investigated. It is found that under different sustained loading levels...

... ABSTRACT Floating facilities with mooring systems have been widely applied in the offshore oil and gas sector and are a viable solution for exploiting offshore wind and wave renewable energy. Plate anchors, an efficient foundation type embedded in the seabed and connected to mooring lines...

... threatens the safety of the floating system. The plate anchor is relatively mobile in comparison with a fixed suction caisson. With appropriate padeye offset, the plate anchor can dive deeper into stronger soils with higher strength under extreme conditions. Therefore, it is reasonable to assume that plate...

... ABSTRACT The vertical loaded plate anchor is a typical foundation of offshore floating production and storage facilities. An important issue is to evaluate the stability and the bearing capacity of the anchor subjected to static and cyclic loads for designers. Model tests of the vertical...

... ABSTRACT Suction Embedded Plate Anchors (SEPLA) have been used as an economical and efficient foundation system in deep waters in support of offshore oil and gas energy development. These anchoring elements are also being considered for support of the Marine Hydrokinetics devices deployment...

... ABSTRACT In this study, the uplift behavior of strip plate anchor embedded in loose, medium-dense and dense sand is investigated by experimental model tests in 1-G condition. The width of the model plate anchor varies from 50 mm to 400 mm and the embedded depth varies from one time of plate...

... ABSTRACT: Suction embedded plate anchors (SEPLAs) are used in deep and ultra-deep waters for temporary mooring of floating offshore structures. Their application for permanent mooring has been considered only recently due to the uncertainties related to their performance during keying...

... ABSTRACT: Plate anchors are increasingly being used to moor large floating offshore structures in deep and ultradeep water. These facilities impart substantial vertical uplift loading to plate anchors. However, extreme operating conditions such as hurricane loading often result in partial...

... ABSTRACT The results of a series of experimental tests on pull out capacity of a typical horizontal plate anchor under different sequential vertical loadings are presented in this paper. The loading comprises of a load applied under undrained conditions followed by consolidation of the soil...

... ABSTRACT In this paper, finite element analyses of plate anchor keying in Normally Consolidated (NC) clay were performed. Bearing capacity of plate anchors was investigated with various embedment ratios and pullout inclination angles. Both vented anchor base (no suction on rear face) and fully...

...Effect of Loading Rate on the Uplift Capacity of Plate Anchors Dong Wang, Yuxia Hu and Mark F. Randolph Centre for Offshore Foundation Systems, the University of Western Australia Crawley, State of Western Australia, Australia ABSTRACT The plate anchor is a relatively new offshore foundation...

... ABSTRACT Plate anchors are commonly used in offshore industry to anchor floating facilities. They are installed vertically using a follower and subsequently rotated, through a process called keying, to exhibit their maximum area normal to the loading direction. This paper describes a series...

... During the installation of Suction Embedded Plate Anchors (SEPLAs), soil in the vicinity of the suction caisson can be disturbed. The effect of the soil disturbed zone on the capacity of plate anchors was investigated in this paper. Both finite element analysis and centrifuge tests were...

... ABSTRACT In the last decade, mooring systems have been selected for the production units and mobile drilling rigs required to operate between about 300 and 3000m of water. The paper emphasizes on the empirical evaluation and installation behavior of suction piles and plate anchors, which...

... that uplift factors and failure mechanisms for pipelines are similar to those found for plate anchors, with comparable uplift capacities approximately 4 to 6 % greater for the pipelines. INTRODUCTION There is extensive use of buried pipelines within the offshore oil and gas industries to transport...

In addition to ESA, there are several types of similar embedded anchors that can be installed by a suction pile, including Suction Embedded Anchor, Suction Embedded Plate Anchor, etc. The cross-sectional shape of the ESA is circular with its diameter being the same...

... ABSTRACT Results of full and reduced scale onshore and offshore testing of a new vertical load capable anchor type, the Suction Embedded Plate Anchor or SEPLA is presented in this paper. The SEPLA plate anchor is unique in that it uses a modified suction pile, renamed a suction follower...
