Sui, Congbiao (author)The shipping industry, which remains the backbone of international merchandise trade, is striving to reduce its operational cost and more importantly its environment impact. New ships need meet the EEDI (Energy Efficiency Design Index) requirements of IMO (International Maritime Organization). However, the current EEDI is not able to accurately...doctoral thesis 2021

Li, X. (author)A flexible riser is a multi-layered pipe device which enables deep-water production by connecting seabed facilities to floating vessels. To withstand huge hydro-static pressure, it is required to have strong collapse capacities. At present, the collapse capacity of a flexible riser is designed based on a "wet collapse'' concept, in which the...doctoral thesis 2021

Huijgens, L.J.G. (author)Requirements on ships are rapidly increasing. In particular, safety and environmental impact are under increasing scrutiny. At the same time, cost and profitability remain as important as they have ever been. These increasingly stringent constraints are beginning to pose problems during the design process. For example, the energy efficiency...doctoral thesis 2021

Li, Z. (author)Surface cracks are serious threats to the structural integrity of offshore metallic pipes. This dissertation proposes a protocol of composite reinforcement on surface cracked metallic pipes subjected to cyclic loads, aiming to decrease the crack growth rate and prolong the residual fatigue life. The main objective of this dissertation is to...doctoral thesis 2021

Sapra, H.D. (author)Modern marine diesel engines operating on conventional marine fuels are unable to further reduce the adverse impact of ship emissions on the environment. Integration of a solid oxide fuel cell (SOFC) and internal combustion engine (ICE) equipped with an underwater exhaust (UWE) can provide the opportunity for mitigating ship emissions and...doctoral thesis 2020

Habben Jansen, A.C. (author)Naval ships are designed to operate in hostile environments. As such, vulnerability reduction is an important aspect that needs to be assessed during the design. With the increased interest in electrification and automation on board naval ships, the vulnerability of distributed systems has become a major topic of interest. However, assessing...doctoral thesis 2020

Zeng, Q. (author)The traditional approach of extrapolating the experimentally measured model resistance of a ship to full scale is based on the Froude assumption or the form factor assumption, where the viscous part and wave-making part of the resistance are dealt with in deep water. In shallow water, however, the water-depth dependency of flat-plate/ship...doctoral thesis 2019

Haseltalab, A. (author)In the last few years, autonomous shipping has been under extensive consideration by academic and industrial communities as well as governmental organizations due to several potential advantages that it introduces. Furthermore, due to the drastic environmental consequences of transport overwater, international organizations have enforced the...doctoral thesis 2019

Chen, L. (author)This PhD thesis investigates V2V, V2I, and I2I cooperation of CMVSs for improving the safety and efficiency of waterborne transport. A predictive motion control framework and a generic negotiation framework are proposed to achieve consensus among controllers. Different applications provide insights into the impact of CMVSs on the performance of...doctoral thesis 2019

Rotteveel, E. (author)This research focuses on identifying the most important stern shape aspects, with regard to resistance and propulsion power, of inland ships. Such information should help designers to determine which hull form aspect to adjust in case design requirements need them to do so. The information is obtained by firstly conducting a large series of CFD...doctoral thesis 2019

Geertsma, R.D. (author)Shipping plays a crucial role in modern society, but has to reduce its impact on the environment. The commercial availability of power electronic converters and lithium-ion batteries provides an opportunity to improve performance of ships energy systems while reducing their environmental impact. However, the degrees of freedom in control for...doctoral thesis 2019

van Ruijven, L.C. (author)This dissertation is about improving performance of projects delivering complex systems. Examples of such systems are ships, infrastructure systems and process plants. Mostly these systems are one of a kind, so called ‘one-offs’ and are the ‘product’ of one or more coherent projects each executed by a consortium of enterprises. The lifecycle of...doctoral thesis 2018

Jain, K.P. (author)The end of life of a ship is determined by its owner on the basis of various commercial and technical factors. Once decided to scrap a ship, almost all end-of-life (EOL) ships are sold to recycling yards for dismantling; except for a few which are converted into museums, hotels, storage, and artificial reefs. As the decision is a commercial one,...doctoral thesis 2017

Liu, J. (author)Ship manoeuvrability is fundamental for the navigation safety of ships. Furthermore, through the equipment used for manoeuvring, it also affects investment, operation, and maintenance cost of these ships. Ships are primarily designed from an economic point of view. To ensure and improve the maritime efficiency, research on inland vessel...doctoral thesis 2017

Rose, C.D. (author)European shipyards specialize in building complex ship types including offshore vessels, yachts, dredgers, and cruise ships. One key difference between these ships and the simple cargo ships typically built in the Far East is the amount and variety of mission-related equipment required to operate the ships. Technical spaces of complex ships are...doctoral thesis 2017

Duchateau, E.A.E. (author)Preliminary ship design (or early stage design in US terminology) is the very first step in designing a new ship. In this stage ship designers attempt to find an affordable balance of the future owner's (customer or operator) ambitions and operational needs. This balance is then translated into more tangible design requirements. However, the...doctoral thesis 2016

van Bruinessen, T.M. (author)Within the ship design industry, and in particular in the development of large, complex and innovative vessels experienced ship designers play an important role in organizing and structuring the design process. How this actually happens within projects that develop such large, complex and innovative vessels for a single client is not clear....doctoral thesis 2016

Hekkenberg, R.G. (author)The European inland waterway transport sector is a highly competitive one. The transport operators in this sector are mainly small companies with only one ship. Such companies have very few possibilities to distinguish themselves from their competitors. At the same time their main asset, their ship, is often highly standardized. In this thesis,...doctoral thesis 2013

DeNucci, T.W. (author)As the complexity of ship design increases, the knowledge used to resolve these complexities is decreasing due to a loss of intellectual resources. In order to remedy these losses, Naval Architects must capitalize on the knowledge available in design teams. The solution to this quandary involves the effective capturing of design rationale. This...doctoral thesis 2012

Van Oers, B.J. (author)Naval architects often say that every ship is a compromise between many conflicting requirements. This widely-held belief immediately raises the question as to what kind of ship and, therefore, what kind of compromise, would suit the ship owner’s interest best. The approach presented in this thesis aims to improve the early stage design process...doctoral thesis 2011
