Workability optimisation of the Stella Synergy: during monopile installation with a motion-compensated gripper and using its DP-system

Using a floating vessel operating on its DP-system and using a motion-compensated pile gripper to install monopiles could be the installation method of the future. Therefore, this thesis focuses on this method. The main objective of this thesis project is to build a model that accurately describes the motions of the Stella Synergy, the monopile,...

To order or not to order: Predicting customer grocery shopping behaviour using multi-label classification techniques

Research and Objective: In the recent years the online grocery sector experienced an enormous uplift and evolved to a highly competitive business sector. Within this demanding environment, the need for strategic information has become extremely important, as it greatly enhances decision-making processes and the optimisation of the supply chain....

Assessing circularity in the end of life phase of public assets and identifying essential requirements for performance measurement

Policymakers and literature have expressed the need for a visual and tangible manner of mapping circular value, the progress towards a fully circular economy and the presence of materials (material passport) in public space. Several initiatives exist for the measurement of circular progress. However, none have explicitly aimed towards the urban...

Benchmarking the Performance of Ports on Asset Management

Over the past decade, the complexity of operations in the port area has increased significantly. As global trade increased significantly, vessel sizes and cargo volumes surged, which places additional pressure on the ports' (physical) assets. Both the challenges the ports are facing and the willingness to ensure continuous improvement have...

Powering a representative ROPAX ferry in 2050 with minimal greenhouse gas emissions

The International Maritime Organization (IMO) issued on the 13th of April 2018 a press release titled: “UN body adopts climate change strategy for shipping”. [1] This document illustrates the commitment of the IMO to significantly reduce the emission of greenhouse gasses (GHG) from international shipping in coming decades. However, the question...

Air-based contactless positioning of thin substrates: Exploring the outlet restriction variation concept

A new concept in the field of air-based contactless positioning has been explored. The concept is based on the variation of the outlet restriction of an actuator, which controls a net air flow starting from the inlet. The object to be positioned ‘floats’ on a thin air film with a thickness in the order of tens of micrometres. Since the film...

A project manager’s journey towards agile project management

Numerical nonlinear analysis of alternate-bar formation under superresonant conditions

Local geometrical perturbations in alluvial channels can generate a pattern of alternate bars. Each bar is accompanied by a pool at the other side of the channel. This pool can decrease the strength of the bank, which can result in bank failure and bars can hinder navigation. Furthermore, non-migrating alternate bars are considered to be a...

Fieldwork coastal engineering, Varna, Bulgaria

On the first day research is done at a beach north of Varna, which is called Sirius Beach. This research is presented in chapter 2. In the research the waterline and cross sections are compared with the previous years. The following is concluded: there is a strong seasonal variation which influenced the measured data, there is a decreasing trend...

Erosion of river banks along the Paraná de las Palmas River, Argentina

One of the branches of the Paraná delta is the Paraná de las Palmas River. This branch doesn’t have the biggest discharge but has the most navigation. The situation in the Paraná de las Palmas isn’t without problems though; the river banks show erosion over the whole length of the branch. This erosion has been investigated by the following...
