Fatigue Life Assessment on the Star Frame of the Ampelmann System

Comparative Fatigue Analysis of a Tidal Turbines Support Structure

Reduced - complexity experiment for validating Fluid-Structure Interaction in ComFLOW

Human activities in marine environment are expanding to more remote locations, exposing offshore structures and commercial vessels to more adverse environmental conditions. On the other hand, market has a continuous demand for more cost efficient designs. Therefore, the need for more sophisticated computational tools arises. In these tools, the...

Proactive Control of Fast Ships: Improving the seakeeping behaviour in head waves

Fatigue resistance of welded joints in aluminium high-speed craft: A total stress concept

Crew transfers, surveillance duties and {security, rescue, interception} operations at sea typically require high-speed craft. Aluminium is quite often selected as hull structure material because of its weight save potential in comparison to steel. The fatigue strength, however, may become a point of concern because of the decreased Young’s...

Longitudinal ultimate bending strength analysis of ship structure for emergency response

The last three years have witnessed many maritime accidents (like “Costa Concordia”, “Mol Comfort”, “MV Smart”, etc), which led to serious consequences including the loss of human life and asset and environment pollution. In order to mitigate loss, maritime emergency response requires time-saving. So, a fast numerical tool is very important for...

The effect of sloshing in partially filled spherical LNG tanks on ship motions

This report describes two methods to analyse the effect of sloshing on ship motions. The first method applies linear potential theory on both the barge and the internal tanks. For the barge the radiation, diffraction and incoming wave potentials are solved. For the internal tanks only the radiation potential is calculated, as there are obviously...

Improving the operability of planing monohulls using proactive control: From idea to proof of concept

The demand to sail at high forward speeds in both calm water and in a seaway remains high. For various patrol, search and rescue or military operations attaining high forward speeds is essential. In head and bow quartering seas, the main factor for voluntary speed reduction is the occurrence of large vertical peak accelerations. The occurrence...
