Experimental study on a breaking-enforcing floating breakwater

Floating breakwaters are moored structures that attenuate wave energy through a combination of reflection and dissipation. Studies into floating breakwaters have been generally restricted to optimising the attenuation performance. This study presents a novel floating breakwater type that was developed to have good attenuation performance while...

Large-scale investigation of wave dampening characteristics of organic, artificial floating islands

The concept of floating vegetation-based islands for the bioremediation of aquatic ecosystems is well known. Less so, their hydrodynamic capabilities regarding the damping performance, positional stability and water-structure interactions. To this end, physical model tests with fully organic, reed-based gabions were carried out in a large...

Optimising the Geometry of a Breakwater Connected to Large Floating Structures: Increasing the Feasiblity of Floating Cities

The development of floating islands is an attractive option to provide living/working spaces at sea, as it would be a more economical solution for many locations at sea where the water depth is high. However, large second-order wave forces cause the floating island mooring system to become expensive as the wave height increases. So, in many...

Force and water jet impact reduction on adjacent structures by means of free surface breakwaters

In head waves, water jet impacts due to run up can occur as a result of the structural configuration of some floating structures, reducing workability. Wave attenuation near the floater may reduce the risk of water jet impacts. This paper presents a numerical study of the performance and attenuation mechanisms of various plate type fixed free...

Wave Attenuation within the Slot of a Floating Structure

In head seas, the offshore construction vessel Pioneering Spirit experiences wave amplification in the slot between its bows. Wave run-up results in a water jet at the closed end. To avoid potential damage of structures in the slot and improve operational safety, more insight into this phenomenon is needed. The aim of this research is to...

Navigating New Horizons: Mapping the Global Technical Potential and Exploring the Material Demand of Offshore Floating Urban Dwellings: A GIS-based Approach Integrating Technical and Motivational Perspectives to Provide Insights into the Global Technical Potential and Associated Material Demand of Modular Floating Structures and Circular Floating Breakwaters as a Proposed Alternative for Sustainable Coastal Communities

Modular Floating Structures (MFS) have emerged as an innovative alternative for sustainable offshore urban development, providing a response to the multifaceted challenges posed by coastal urban expansion: significant urban growth and coastal migration, increasing sea-level rise exposure and land scarcity. This thesis presents a geographically...

The potential of end-of-life ships as a floating seawall and the methodical use of gap resonance for wave attenuation

This study examines the potential of a new type of floating seawall, made up of retired large-scale oceangoing vessels, to be used in open water and exposed coastal areas. The main objectives of the research are to assess the effectiveness of the floating seawall concept, to determine the contribution of the gap resonance to wave attenuation,...
