The Sailing Tug: A feasibility study on the application of Wind-Assisted towing of the Thialf

The international maritime sector accounts for about 2% of all global carbon dioxide (CO2) emissions, the main greenhouse gas that causes global warming. Nations meeting at the United Nations International Maritime Organization (IMO) in London have proposed an initial strategy for the reduction of greenhouse gas (GHG) emissions from ships,...

A Combined Breakwaters System: A Wave Attenuation Study on the Combination of Submerged and Floating Breakwaters using REEF3D

Coastal zones have been a dynamic area and most favoured locations utilized for living, leisure, recreational activities, tourism, commerce and many other human activities. Submerged and floating breakwaters have been used as effective systems to protect these zones from wave attack. However, they are only effectively functional if the incident...

Impact of box-type floating breakwater on motion response of hydrodynamically coupled floating platforms downstream

Floating breakwaters are applicable in several offshore applications to protect downstream structures from excessive wave loads and to reduce their motion response. This thesis investigates the impact of the leading platform, functionally a breakwater, on the RAOs and response of the platforms behind it in frequency domain. The structures are...

Simulating wave attenuation by an offshore floating solar system

Because the demand for green energy increases rapidly, it is expected that solar and wind energy will dominate future power generation. New in this field is the development of offshore floating solar systems, consisting of multiple interconnected platforms that are covered with PV panels. Besides satisfying the demand for electricity, these...

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...

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...
