Methanol Hybrid Offshore Working Vessels: A technical, environmental and economic assessment

To support Van Oord’s path towards a low-emission future fleet, this thesis has focused on the technical, environmental and economic impact of a methanol hybrid power plant design for new-build offshore working vessels (OWVs). These Dynamic-Positioning (DP) vessels are known for their large and dynamic power plants and have to limit their NOx...

Invasive Coronary Artery Imaging Using Optical Coherence Tomography: A Cost-effectiveness and Implementation Process Analysis

The aim of this project was the implementation of optical coherence tomography (OCT), an invasive intracoronary imaging (ICI) tool used for the visualization of coronary arteries. The implementation was performed in a structured manner by: (1) A literature review into the current applications of OCT in relation to current standards; (2) A thesis...

The effects of upcoming emission regulations on the selection of suitable prime mover combinations for the future harbour/terminal Rotortug: A decision-support tool

Nowadays the interest for environmental issues is steadily gaining ground. Inescapably, the shipping industry, is also called to contribute its fair share towards the reduction of air pollution. Harbour tugboats need to comply both with international but also with local exhaust air emission regulations, which are anticipated to become more...

A change of state: A thermodynamic and cost-effective optimized Trombe wall based on latent heat storage (LHS) for year round application

The following graduation thesis "A change of state: A thermodynamic and cost-effective optimized Trombe wall based on latent heat storage (LHS) for year round application” aims to investigate and optimize the thermal energy performance of a Phase change material (PCM) Trombe wall to create an economically feasible product. This passive system...

Cost-effective levee design for cases along the Meuse river including uncertainties in hydraulic loads

After the flood of 1993 and 1995 in the Netherlands, flood risks in Limburg became an important discussion. Each flood defence system along the river Meuse needs to be provided with a safety level with an annual failure probability of 1/250. In the nearby future a new safety philosophy will be introduced, entailing new safety norms and...

Towards value increase in urban regeneration: A study of how value engineering could be used in order to increase the value of urban regeneration projects

By the means of urban regeneration, municipalities aim to increase the current value of an urban area. This so called ‘value improvement’ is obtained when extra performances achieved by urban regeneration outrun the life cycle costs for it. This implies that if both parameters are quantified the decision making process becomes more transparent....
