The AMS-FLOW Project

Anchor and mooring selection for FLOW
Introduction

The project aims to contribute to Ireland's Climate Action Plan by developing and implementing offshore renewable energy projects, specifically focusing on floating offshore wind (FLOW) technology. The project seeks to address various technical challenges associated with scaling up FLOW installations, such as understanding met ocean conditions, optimizing mooring and export cable performance, and exploring emerging anchoring technologies.

The project's key objectives include developing a method to quantify combined wind and wave conditions, designing an innovative mooring arrangement utilizing domestic materials and technology, conducting testing on emerging anchoring systems, creating a techno-economic model for installation, assessing environmental impacts, and developing an early-stage decision toolkit. The project aims to go beyond the state of the art, particularly in the first stage, by introducing novel methods and arrangements for characterization and testing.

The anticipated impact of the project is to enhance confidence in the offshore renewable energy sector by providing high-quality experimental data. The results and deliverables of the project will be made available to various stakeholders, including FLOW developers, the domestic supply chain, marine technology companies, policy makers, and public bodies.

Project Duration

March 2024 - February 2027

Objectives
  1. Develop and define a novel method to characterise quantitatively combined wind and wave conditions, with reference to an exemplar FLOW system
  2. Design a cost-effective mooring arrangement less reliant on steel chain, validating fibre/synthetic rope and load reduction device that meets the loading resistance required
  3. Carry out numerical modelling (Plaxis) on the performance of emerging anchoring systems
  4. Anchoring - new experimental data on emerging types/novel design
  5. Parametric study to identify the optimal geometries required for anchor systems in different soil conditions using numerical models in this application
  6. Techno-economic model of combined mooring and anchor combinations
  7. Assess the impact of adopting new mooring and anchoring technologies to the broader (installation, vessels, environment) FLOW project
  8. Develop an early-stage decision tool kit based on anchor, mooring and topside loading data (excel tool, tabulated performance indicators and guidelines). This toolkit will also integrate results factoring in costings, environmental and installation considerations
