van Veggel, Stein (author)In the field of soft robotics, rigid joints and links are replaced by soft, deformable elements, This causes soft continuum robot arms to excel in unpredictable environments, but to face challenges during control and shape reconstruction. The sensing ability present in octopus suckers provides inspiration for solutions. Octopuses employ their...master thesis 2023

den Tonkelaar, Bram (author)To keep the global warming of the Earth to a minimum, the greenhouse gas emissions need to be reduced. Van Oord aims to be carbon neutral by 2050; therefore, Van Oord is exploring alternative fuels. Ammonia is a promising option to use as a fuel due to the forty times lower well-to-wake emissions than MGO when it is produced with green energy....master thesis 2023

Berkouwer, Laurens (author)For the installation of suction pile jackets, a new installation method initiated by SPT Offshore could extend the allowable size for suction pile jackets used as foundations for offshore wind turbines. This method involves installing the suction piles separately from the jacket frame. First, the suction piles are installed on the seabed. Then,...master thesis 2023

Sharma, Astha (author)In the past decade, suction caissons have emerged as a preferred offshore foundation solution for wind turbines due to their silent installation process and potential for recyclability. However, there has been growing speculation regarding the necessity of under base filling, which involves filling the gap between the top plate of the suction...master thesis 2023

Tsota, Marinansy (author)Suction caisson jacket (SCJ) is one of the most promising substructures, under certain conditions, for offshore wind turbines. Their unique characteristic of large diameter (D) compared to their small wall thickness (t) conducts them an object of study, concerning their transportation to the offshore location, as their structural stability...master thesis 2023

de Vries, Ellen (author)Suction grippers have the advantage to handle many different types and sizes of items, without being restricted by the dimensions of clamps to enclose an object and to handle objects more delicately. <br/>However, the challenge of attaching these grippers to irregularly-shaped and rough surfaces remains a persistent issue. Despite advancements...master thesis 2023

Dijkstra, Jesse (author)Cutter suction dredgers (CSD) are highly vulnerable to large wave loading due to their stiff, spud-based mooring. Many mitigations targeted at reducing the resulting stresses on the spud and other critical operating components have been proposed in recent years, most notably by adding a level of flexibility to the connection between the pontoon...master thesis 2023

Aydin, Güven (author)Treatment of prostate cancer can be done by performing brachytherapy, where radioactive seeds are transperineally implanted in the prostate via needles. A known problem during treatments with needles is the risk of targeting errors caused by the deviation of the needle from the planned path in the prostate. One of the main sources of this error...master thesis 2023

Seegers, Daan (author)This thesis combines a high-tech, capital product, with servitization methods in order to create a product-service system. Servitization has allowed companies to align their interests and create a co-creation environment. The overall objective of this thesis was to find an improvement over the current service design of Beaver vessels. This new...master thesis 2022

Mascini, Marjolijn (author)River dikes in the eastern part of the Netherlands are characterized by a relatively low daily water table. In the unsaturated zone above the water table, a negative pore pressure (matric suction) is present that binds the soil particles together. Suction can be especially large in soils with small grains, such as clay, and increases the...master thesis 2022

Christantonis, Evangelos (author)Offshore wind turbines are getting larger and are being installed in ever deeper waters. This requires increasingly stronger yet affordable foundations. The Tri-Suction Pile Caisson (TSPC) is a Wind Turbine Generator (WTG) foundation concept patented by SPT Offshore that requires a smaller amount of structural steel or concrete than a...master thesis 2022

Cleijpool, Bram (author)The detachment of a product from a suction cup gripper is a challenge that emerged in recent years in the high-speed case packing of packaged food. In this industry suction cups are used to temporarily attach a product to a case packing robot. The detachment of products from the suction cup gripper threatens throughput. In, some cases, the...master thesis 2021

van Koten, Koen (author)In this thesis I will show the realisation of a multiline anchor system using a suction pile anchor (SPA). From the literature research it can be concluded that the SPA is a suitable anchor for a multiline anchor system and that the most probable mooring configurations will be either the original single-line, the 3-line or the 6-line system....master thesis 2021

van Tilburg, Floris (author)Suction based robotic actuators have potential for the bin-picking industry, but are currently not usable due the needed speed, accuracy and ability to handle novel and adversarial objects. An evaluation of the state of the art grasp pipeline developed by Mahler et al. [1] for detecting grasps on novel objects lead us to split the problem of...master thesis 2021

Groen, Gijs-Bart (author)Laparoscopy is a type of minimally invasive surgery in which instruments with long, slender shafts between handle and end effector are inserted through small incisions in the abdominal wall. A laparoscopic aspirator-irrigator (LAI) has a hollow shaft used to evacuate undesirable substances using a vacuum pressure, rinse tissue using a stream of...master thesis 2021

Kortman, Vera (author)Gripping slippery, compliant, and irregular tissues during MIS is often challenging using a conventional gripper. A force grip has to compensate for the low friction coefficient between the gripper’s jaws and tissue surface. This study focuses on the development of a suction gripper as an alternative for the well-known tissue gripper. Suction...master thesis 2021

Eikhout, Pippi (author)Offshore pipelines represent major items in the oil and gas industry nowadays. These submarine pipelines are usually covered with backfill for protection and a well-known method for this is sand backfilling with a trailing suction hopper dredger (TSHD). Although pipeline installation with a TSHD is a developed technique, there are still some...master thesis 2021

Joosen, Max (author)Sentinel lymph node biopsy (SLNB) is a procedure that is used to determine the stage of disease of melanoma patients and determine further treatment. However, the morbidities accompanied with this procedure are not negligible (e.g., wound infection, lymphoedema and seroma). With the goal reduce the incidence of morbidities, this thesis...master thesis 2021
