Fiber optimization of a carbon windsurfing boom: FEM fiber optimization for mass and stiffness

The goal of this research is to optimize the fiber layup of a carbon windsurfing boom for weight and stiffness. A windsurfing boom should be stiff to provide an efficient basis for the energy transfer from the sail through the surfer to the board. The weight of the boom is important as the total weight of the rig influences the performance,...

Probabilistic Lifetime Predictions Using Total Stress Concept, Remote Monitoring and Global Wave Forecast Models: Fatigue Analysis of Damen’s FCS5009 Vessels

At Damen’s Research and Development department, continuous improvements are made to existing design practices using recent technological developments and fatigue design is currently on the anvil. High speed craft operating around the globe are subject to millions of load cycles (resulting from ocean waves) and therefore suffer from metal fatigue...

Flexible Floating Island

Nowadays, fears over rising sea levels due to global warming have prompted many countries with lands below sea level to find solutions to ensure the safety of nation and citizen. Furthermore, the development and utilization of marine resources have always been a topic of interest. Due to these necessities, the concept of flexible floating...

Defining a solid approach for designing a bridge landing against fatigue

Offshore oil and gas projects usually require the presence of more than one facilities in the same location. These facilities need to be connected with each other in order to enable the transfer of personnel among each other. As a result, bridges are implemented for such purposes with their ends being positioned at extensions of the two...

The evaluation and improvement of the hydrodynamic behaviour of mechanically coupled barges: A novel decommissioning method for oil and gas platforms in the North Sea

Allseas' Pioneering Spirit is the largest heavy lift vessel in the world. It uses its u-shaped bow to sail around an offshore platform and lift topsides up to 48.000t in a single lift. Despite being the largest vessel in the world, platforms exist that are simply too heavy, or too large to fit in between the bows of the vessel. Besides, smaller...

Towards Numerical Hydromechanics Analysis of an Arbitrary Shape Floating Body in Ice-Infested Waters

In the last couple of decades, Arctic Engineering has become a topic of interest. There are still plenty rooms of research to understand the unique characteristic of sea ice, especially in relation to offshore engineering. This includes the most fundamental problem in floating body motion analysis: the radiation-diffraction problem. A powerful...
