... for research and the opportunities for innovation. This analysis focusses on the installation suitability and concept-level sizing of a common anchor type – the drag embedment anchor – across the UK sea regions. This methodology leads to an estimate of the number and weight of drag anchors and the length...

... is to place a large anchor at one end of the pipeline, or mid-line anchors installed to each side of the pipeline along the route. However, such anchors require pre-installed attachment points on the pipeline. A more elegant and efficient approach, demonstrated by recent research, is to install or retrofit...

... ABSTRACT: Offshore wind (OSW) power cable failure currently accounts for 75% of the cost of all insurance claims associated with OSW projects and faults typically take 100+ days to rectify. The most effective method for protecting the cables from anchor damage is to bury them in the seabed...

... ABSTRACT: Seabed trenches near the anchors reduce the anchor capacity, which increase failure risk of the mooring system. The trench formation is related to the mooring line-seabed interaction. Thus, one method to inhibit trench formation is to reduce the soil region disturbed by the moving...

... will require different anchoring solutions. In this work, we integrate publicly available data to assess optimum anchoring solutions for future floating wind developments in support of early engineering, installation analyses, and cost modelling. 1 Introduction 1.1 Offshore floating wind in the Celtic Sea...

... ABSTRACT: Drag embedment anchors are a technology that has developed through many years’ experience. However, as demand increases for anchoring of clean energy technologies offshore, so the requirements of modern drag embedment anchors have evolved. A more resilient infrastructure requires...

... ABSTRACT: This study presents analysis of a floating offshore wind system to illustrate methodologies for reducing the mooring loads transmitted to the anchor and the required anchor size. These design efficiencies support acceleration of the development of floating offshore wind, to help meet...

... ABSTRACT: Offshore floating facilities require mooring systems to keep them in position to resist environmental loads. Mooring lines connecting anchors and floating facilities include a segment in soil and a segment in water. Though usually separated during analysis, ideally, the embedded...

... ABSTRACT: Upscaling of screw piles has been proposed for offshore use in foundations and anchors. This upscaling can result in a significant increase in vertical installation forces. Subsequent research has shown that this can be reduced and even eliminated by using over-flighting techniques...

... ABSTRACT: To reduce the cost of mooring for floating offshore wind turbines, the so-called Dynamically Installed Anchor can be a viable solution. However, to use this anchor on a large scale for floating wind farms, a better understanding of the soil state after installation is needed...

... ABSTRACT: In various cable routing and burial depth designs use has been made of a series of offshore anchor dragging tests in sandy seabeds in the German Bight that TenneT executed in 2013. The test results were made available in the public domain, but the application of the results...

... ABSTRACT: Significant growth of the floating offshore wind sector is anticipated over the next decade as developers target increasingly deeper sites. The efficient design of mooring systems and innovative anchor layouts will be critical in driving down the cost of this technology. Sharing...

... ABSTRACT: The widespread use of Rock Anchor (RA) systems supported by the increasing demand of offshore energy requires the development of a design method that should be simple to use, efficient and most importantly reliable. In the past decade the development of such analytical tools has...

... in the development of floating offshore wind energy industry. The dynamically installed multi-line anchor (DIMA) can provide significant capital cost savings by reducing the number of anchors. DIMAs are usually subjected to combined vertical-horizontal-moment-torque ( VHMT ) loading caused by wind, waves...

... ABSTRACT: Plate anchors offer a cost-effective anchoring solution for offshore floating energy devices. This study aims to investigate the uplift capacity of horizontal plate anchors in dense sand using the critical state-based model NorSand implemented in finite element (FE) software Abaqus...

... ABSTRACT: This study investigates the performance of circular plate anchors under vertical cyclic loads in dense sand. A numerical analysis implementing SANISAND-MS constitutive model is employed to capture the accumulated displacement under cyclic loading. The variation in mean load, cyclic...

... ABSTRACT: This paper describes a metamodelling approach to investigate the behaviour of a plate anchor in spatially variable soil. The approach explores the effect of variability in undrained shear strength on the monotonic holding capacity. The problem is firstly analysed through a selected...
