Willems, Jasper (author)As a big contributor to the the global emissions, the maritime sector strives to bring down its greenhouse gasses and hazardous emissions by enforcing increasing strict rules on the exhaust gasses. This gives major challenges to the maritime sector to develop greener modes of transportation. This report investigates the in-cylinder starting...master thesis 2023

Elmazi, Enri (author)The maritime sector is important for the facilitation and growth of global trade. Currently, about 90% of the goods are transported by ships and as a result, the number of ships has risen, increasing the emissions related to shipping. Pollution caused by exhaust gas, especially the sulphur oxide emission, from marine diesel engines has become a...master thesis 2020

Hu, Y. (author)In this thesis, a new method of sizing marine equipment will be applied to main components of marine auxiliary systems. The new method is called 'first principle' method. This new method will be applied to other marine system components; namely shell and tube heat exchangers, plate heat exchangers and centrifugal pumps. The results prove the...master thesis 2016

Rekelhof, B.M. (author)Low loading of diesel generators is considered to be a major problem for all-electric offshore vessels performing DP-operations. Low loading, often caused by system dimensioning for peak conditions and high redundancy requirements, leads to increased engine wear, fuel consumption and emissions. In this research, a Royal IHC designed DP2 class...master thesis 2016

Bakker, F.C. (author)This Msc graduation study covers the installation of topsides on a jacket by an offshore heavy lift crane vessel, and its related problems. One of the problems take place after the topside is hoisted on the jacket, during the weight shift from the hoist cable onto the jacket. The topside then exerts large horizontal forces upon the crane and...master thesis 2015

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

Jacobs, Isabelle (author)This graduation thesis studies the CI combustion of ammonia and hydrogen in an ICE. It contains a review of the literature and a modeling study of the ignition and cylinder performance of the AmmoniaDrive test engine. AmmoniaDrive is a NWO-funded research project that aims to decarbonize shipping by introducing an ammonia-fuelled SOFC-ICE power...master thesis 2023

Kortenhorst, Julia (author)Traditionally, ships are powered by fossil fuels in combustion engines, causing 3% of global greenhouse gas emissions. Alternative installations have yet to prove their reliability and are currently not as cheap or technological ready. <br/>To enable ship-owners to prepare their ship for the future, but postpone their decision on which...master thesis 2020

Boekhout, Martijn (author)The shipping industry has a notable share in global greenhouse gas emissions and other pollutants such as sulphur and nitrogen oxides. Fuel cells and batteries are identified as relatively new technologies for shipping with high potential and hydrogen is also considered as one of the most promising sustainable fuels, especially for smaller...master thesis 2020

van Leeuwen, Simon (author)All ships rely on many on board systems to reliably complete their missions (e.g. transporting containers, laying pipes or protecting the seas). However, for many of these ships, the detailed design of these systems is put off until the later stages of the design. For most ships, this will create no problems. However, for those complex vessels...master thesis 2017

Pothaar, Maarten (author)Progressing targets on GHG emission reduction urge the the Netherlands Ministry of Defense (NL MoD) to reduce the use of fossil fuels, as they announced to contribute to the Paris agreement by reducing its dependency on fossil fuels by at least 70% by the year 2050. However, without sacrificing striking power, because future naval combatants...master thesis 2022

Boxma, Timo (author)As the shipping industry needs to become greener, it has to move away from fossil fuels. For deep-sea shipping, ammonia is marked as a high potential fuel. The AmmoniaDrive concept feeds the anode-off gas from a Solid Oxide Fuel Cell (SOFC) and additional ammonia into an Internal Combustion Engine (ICE). The exhaust gas coming from the ICE can...master thesis 2021

Belmer, Rebecca (author)Introduction - Hydrofoils are often used for high-performance craft. They enable the hull to rise out of the water and reduce drag. A recurring problem is ventilation, this is the presence of a cavity filled with ambient air on the lifting surface. Ventilation causes the lift of the hydrofoil to decrease drastically. A lot of research has been...master thesis 2023

Wang, Xiaozhe (author)The ship propulsion system model is simulated by MATLAB/Simulink initially and is required to reproduce the simulation results in python. This master graduation project deals with the reproducibility of ship propulsion system model by different computer simulation tools. The MATLAB/Simulink model will be provided by Maritime Technology (MT)...master thesis 2019

ten Hacken, Marjolein (author)A naval submarine has to cope with different operational modes: sailing at<br/>the surface, just below the surface or fully submerged and at different speeds.<br/>Therefore it needs an appropriate power plant. In this research a first principle<br/>submarine propulsion model has been extended with a Proton Exchange Membrane<br/>Fuel Cell (PEMFC)...master thesis 2017

van Leeuwen, Menno (author)Cutter suction dredgers are a type of hydraulic dredgers often used in areas with hard soil where other types of dredging vessels would be ineffective. As a result of the wide range of type of soil that is being cut a lot of variation is seen in the power demand on the cutter suction dredger's diesel-electric power generation system....master thesis 2017

Zhao, Shimeng (author)The world is moving towards a cleaner future. With the increasingly stringent emission regulation in maritime field and the limitation of marine diesel engine systems, the shipbuilders may start to seek cleaner solutions rather than modifying the currently prevailing internal combustion engine systems (ICE). According to previous researches, a...master thesis 2017
