Bajic, Tomi (author)An unfamiliar subject to the contemporary connecting options for cranes on pontoons is removability; Various difficulties and obstructions related to the heavy-duty nature of the equipment lead to a limited amount of practiced conventional connecting options for this purpose, which all have the absence of removability in common. Furthermore, the...master thesis 2024

Krielaart, Thomas (author)Crane hardstands serve as crucial platforms for supporting heavy lifting equipment and ensuring operational efficiency. However, crane hardstands are not infinitely stiff and will deform upon loading. Uneven loading during wind turbine installation will result in differential deformation of the crane hardstand, causing the crane to tilt. A small...master thesis 2023

Koetzier, Daan (author)Floating offshore wind turbines offer a means to access wind resources in waters that are too deep for bottom-fixed offshore wind turbines. To operate a floating wind farm, it must be possible to perform maintenance on the turbines. A critical maintenance aspect is the exchange of a major component such as a blade. It involves a lift of a large...master thesis 2023

Hoeksma, Bram (author)Currently, our society faces a pressing challenge: global warming. The solution lies in the energy transition, which replaces fossil fuels with clean sources. This requires a global effort across all sectors, including shipping. While a significant portion of shipping relies on polluting fuels, the European Union’s Green Deal aims for climate...master thesis 2023

van Meijeren, Michelle (author)Electrification of numerous end-users is a worldwide trend to address climate change, according to the International Energy Agency. This trend has also reached container terminal operators. Currently most of the ship-to-shore cranes employed are electrified, leading to an increase in the required electrical power demand and to an increase in the...master thesis 2023

Veršnik, Ana (author)The success of offshore wind farm installations is often related to the costs and time taken to be completed. Current installation strategies require several critical offshore lifts for the completion of a single wind turbine, as in most cases each component gets installed separately. This is time-consuming and has a direct link to the cost of...master thesis 2023

Appert, Loïc (author)Due to the increasing size of offshore wind turbines, the jack-up vessels and cranes installing them need to increase in size. The increase in length of the crane boom results in an increase of the dynamic response of the crane. This increase in response results in higher loads in the crane. The magnitude of the higher loads are unknown and not...master thesis 2023

Scherpenhuijsen Rom, Erik (author)This paper provides an initial feasibility study of the potential installation of iron powder energy generation systems aboard a marine service vessel. After a short introduction as to the relevance of this study, the state-of-the-art iron powder energy generation is investigated. This information is then used to decide which marine service...master thesis 2023

van der Kaaij, Isabelle (author)Offshore wind energy is poised for significant growth, with three major trends emerging: larger wind turbines, offshore wind farm sites in deeper waters further from the coast, and a shift towards floating offshore wind energy. While current floating wind turbines are installed using a tow-to-site strategy, the increasing size of turbines and...master thesis 2023

Pfeiffer, Marijn (author)To overcome the problem of wave-induced vessel motions on the crane tip, technologies have been developed to compensate for these motions. Most vessels nowadays, are equipped with dynamic positioning systems, these systems reduce the yaw, surge and sway movement of the vessel. This leaves, the motions roll, pitch and heave uncompensated. To...master thesis 2022

Gerlach, Laurens (author)Quay cranes on modern container terminals have the possibility to lift two 40ft. containers side by side. In order to be able to perform this type of lift, the crane must be equipped with a tandem spreader. As this type of spreader cannot be used for performing certain lifts, such as the handling of hatch covers, switches between single spreader...master thesis 2022

Roest, Leon (author)As a result of the need for higher productivity ship-to-shore container cranes, seven concepts are composed that can simultaneously transfer 4 Twenty Foot Equivalent Unit containers. All concept can be built on a standard ship-to-shore crane structure. These concepts are based on working principles found in (patent) literature. The concepts are...master thesis 2022

Rasch, Tycho (author)Wind loads acting on STS cranes are an important design parameter to be taken into account when designing STS cranes. Current calculation standards such as the EN13001-2 overestimate wind forces. The goal of this research is to propose an improvement on current calculation standards. Wind tunnel tests were performed to assess the results of...master thesis 2022

Driessen, Mark (author)Current service and installation activities to offshore wind turbines (OWTs) are mainly carried out by jack-up vessels. These vessels are less susceptive to disturbances caused by sea waves when they lift their hull from the water level by jacking down multiple legs to the seabed. An alternative is a crane mounted on a floating vessel, which has...master thesis 2021

van Engelen, Niels (author)Due to a high demand for offshore wind energy the industry is expanding to evermore challenging locations such as seismic prone areas. The corresponding seismic shocks and vibrations can be transmitted to jack‐up vessels and their cranes used for the installation of these offshore wind turbines. Since a potential collapse due to seismic activity...master thesis 2021

Boll, Lars Christian (author)During offshore construction with a Semi-Submersible Crane Vessel (SSCV) the vessel is station keeping by means of Dynamic Positioning (DP). DP enables a vessel to keep position and heading by utilizing its own propulsion, while being exposed to the environmental forces caused by waves, wind and current. In a comparison study between offshore...master thesis 2020
