The design, production and verification of a fully elastic model of a catamaran for hydroelastic experiments

Catamarans are popular in the offshore sector as they combine good transverse stability and ample deck space with low wave resistance. However, their slender hull shape results in low restoring qualities in heave and pitch motions. The large motions in rough weather can often result in water impacting the underside of the deck connecting the two...

Floating Solar: A Hydroelastic Method

With the climate goals of the Paris Agreement and the European Green Deal, countries need to reduce their carbon footprint and increase their renewable energy production. For countries with high population density, land-based photovoltaics (solar) takes up valuable space. Therefore, solar application at sea is considered. <br/><br/>One of the...

Hydroelastic Analysis of a Multi-Module Very Large Floating Structure

This thesis concerns a hydroelastic analysis of a multi-module very large floating structure (VLFS), analysed in the frequency domain. To this end, the fluid-structure interaction is described by a 2D model, where the VLFS is represented by four floating beams interconnected with rotational springs. The fluid is modelled as an ideal fluid, and...

Approaching hydroelasticity of large vessels with multi-body dynamics

The size of vessels has increased significantly over the last decades and will increase even further in the decades to come. This trend is mainly visible in the size of container ships. A decade ago the largest container ship had a capacity of 13.500 TEU, nowadays the largest container ship has a capacity of almost 24.000 TEU. The capacity of...

Influence of Lightweight Flexible ULFS on Surface Waves

Floating offshore solar platforms (FOSPs) are envisaged to become Ultra Large Floating Structures (ULFS) with horizontal dimensions of several kilometers. The payload of these structures comprises mainly the photovoltaic panels as well as cabling and limited electrical equipment. Thus the payload per unit area of these FOSPs is very low....

Analytical Modelling of Fluid-Structure Interaction: On Developing Equations to Understanding Rizos' Experiment (2016)

The activities of humans in the marine environment are on a steady rise; this trend follows the exposure of offshore structures and vessels to harsh environmental conditions. On the other hand, there is continuous demand for lighter, faster and more efficient vessels. Technological advancement in composite materials and better design methods...
