The Ampelmann system uses a motionless transfer deck on a host vessel to transfer personnel and equipment between the vessel and offshore structures very safely even in very harsh environment. The Ampelmann system consists of a transfer deck which is mounted on a hexapod and a gangway. The hexapod is a so-called Steward platform which...

The increasing use of Fibre Reinforced Polymers produced by Vacuum Assisted Resin Transfer Molding in civil infrastructure applications leads to the need for an appropriate research data. The VARTM produced structural elements are not limited in dimensions and material properties and typically are slender structures parts of which are...

Accurate dry mass prediction is essential in early design phases of a launch system. To predict structural mass
of a launch vehicle more accurate at a conceptual design phase, a structural mass model was developed. The model
predicts a launch vehicle’s structural mass, thickness, center of mass and mass moment of inertia. Load carrying...

The S-lay pipeline installation method is characterised by its fast installation process and its application in all water depths. Offshore standards and design codes provide local buckling checks for combined loading criteria for load controlled and displacement controlled conditions, where a load controlled condition is defined as a case in...

Future wind turbines require larger rotor blade radius, leading to an increase of rotor swept area. The larger rotor swept area results in more energy production of the wind turbine. Further increase is however limited as a result of the structural weight, which induces a large bending moment and could result in buckling of the rotor blade. An...

An enhanced methodology is proposed to include both the loading and the resistance of the upper stem (pipeline) in 18" ILT installation. Loading behavior and buckling capacity have been investigated. The upper stem behaves quasi-statically for all HMC projects, this corresponds to the current method of applying maximum found loads statically....

Shells tend to be thin because their curvature enables them to carry distributed loads as membrane forces. The property of thinness stems from shells’ capacity to store membrane strain energy without much deformation. As a result, buckling failures often govern the design of shell structures. These buckling failures usually start locally, at a...

The trailing edge of wind turbine blades are commonly manufactured as an adhesive joint of the pressure-side and suction-side composite panels of the blade. Under some conditions, a lead-to-trailing (LTT) edgewise bending moment can induce buckling at the trailing edge adhesive joint, which may lead to early failure of the blade due to...

Offshore pipelay is the operation of laying a pipe from a surface vessel to the seabed. As the suspended pipe approaches the seabed, it bends downwards forming the sagbend. The sagbend is controlled by the vessel position and a tensile load is applied to counteract the weight of the pipe. During the engineering phase of previous HMC projects,...

Heerema Marine Contractors is an offshore contractor who specializes in the installation and removal of a range of offshore facilities. This includes the installation of submarine pipelines in excess of 1500 [m] water depth. Higher water depths drive the pipeline designs to increase wall thickness. Another motive to apply a low D/t ratio is to...

Even though for most hydraulic and geotechnical structures clear guidelines are available, those for flexible dolphins are still missing. Consequently, whether a design is safe is usually subject of debate. Economical dolphin piles are large diameter tubular piles, susceptible to local buckling. After installation the embedded part of these...

A one-dimensional analytical solution to predict buckling-induced delamination growth was developed toward an efficient and effective engineering application. The postbuckling solution for a composite beam was first obtained with nonlinear deflection approximations based on 'thin film' assumption. An interlaminar stress analysis method was then...

This MSc thesis addresses the study of buckling and post-buckling of composite plates with elastic restraints at the edges and under any combination of in-plane loading, aiming to solve the plate response in stiffened panel structures. The implemented solutions are based on thin plate theory for mid-plane symmetric plates. The governing...

Localized buckles can occur in crashes when compressive stresses are dominant. However, due to their local appearance, they might be overlooked by a finite element analysis, meaning that local failure due to buckling will not be predicted. Methods to analytically assess the onset of such buckles are readily available. However, an off-the-shelf...

Even though composite materials are being applied more and more often, these materials are often not used to their full potential. In particular, composite materials are very sensitive to Compression-After-Impact (CAI), typically leading to knockdown factors in the order of 0.65. Many researchers have tried to predict the effects of Compression...

Bending behaviour of steel tubes has been examined in many research projects through the years, especially for empty ones. Also the infill and pressure effect in the tubes has been elaborately investigated but not much has been done on the effect that the sand infill has on the bending of the tubes. Combi-wall tubes are filled with sand during...

This thesis continues the work performed by Ferreira and Almeida on the topic of weight and cost reduction of composite multi-spar torsion-bending boxes. The goal is to find the influence of changes to the structural configuration on the resulting weight of said torsion-bending boxes. Using analytical methods, combined into the BoxSolver MATLAB...

This master thesis investigates the response of spirally welded steel tubes under 4-point bending deformation. Through the finite element simulations of a testing the buckling behavior of sprirally welded tubes can be more clearly understood. The numerical simulation and buckling behavior of spirally welded steel tubes is discussed in this...

This master thesis presents research into buckling of thin hyperboloid shells structures. This type of structure is typically applied as the large cooling towers at coal fired electricity plants. However, modelling cooling towers is not the objective of this research. The objective of this research is to understand the buckling behaviour of...
