Weight Estimation of Superyachts

Superyachts are expected to be perfect since the owner pays millions for them, and the worst that could happen is tilting the ship once it floats. The lightweight, including the center of gravity, is essential to know with a high degree of certainty to prevent this. However, the lightweight is already expected in an early design phase, when...

Operational Characteristics Of A Metal Supported Solid Oxide Fuel Cell Power Generation System On Methanol For Naval Applications

The characteristics of a metal supported solid oxide fuel cell on methanol is analysed in as the power generator in a balance of plant consisting out of a reformer, combuster, heaters, pumps, turbines and tubes. The system is reviewed on performance regarding efficiency, power density, fuel utilization and viability for marine applications.

Topology optimization for ship structures with manufacturing constraints

Currently, most ships are designed on the basis of rules and reference ships for which often only the critical structural parts are calculated and designed in detail. This process can result in an over-dimensioned ship with the standard structural outcome of longitudinal stiffeners, transverse stiffeners, and bulkheads with a fixed distance due...

The fuel cell powered superyacht: A research into the possibilities and consequences of using fuel cells to provide a superyacht in its energy demand

One of the most important reasons to investigating fuel cells is the increased level of regulation regarding emissions in the maritime sector, while fuel cells offer the opportunity to reduce these emissions. It was not clear what the impact of these systems would be on a yacht, the aim of this project is therefore to gain more insight into...

Economic feasibility of a hydrogen-fuelled marine transportation system: Case study of a bulk carrier at CMB

The crises of global warming, air pollution, acid rain and the running out of oil make the investigation into alternative fuel technologies crucial. New technologies are being investigated on a global scale in an attempt to address these problems. This thesis investigates the use of hydrogen-diesel dual-fuel engines and fuel cells. The economic...

A decision-support method to meet the emission standards in shipping: The case of Seatrade

Due to the increased social importance and regulations on shipping emissions, effort must be made by shipowners, operators and naval architects to reduce the amount of air emissions from ships. A large set of emission control methods exists, but compatibility and interaction issues complicate their implementation. This thesis contains a decision...

Organic Rankine cycle as waste heat recovery system for marine application: Screening methodology, modelling and analysis

Carbon dioxide emission into the earth’s atmosphere by maritime activities are a concern for the people within and outside the industry. This is because of the environmental impacts that are caused by these greenhouse gas emissions which changes the very chemistry of this planet. These impacts can be mitigated by reducing the CO2 emissions which...

Case Based Reasoning: As a Cost Estimation Method for the Ship Building Industry

Accurate cost estimations are important for ship production companies such as Royal IHC. The research discussed is based on a feasibility study for a CBR cost estimation method. The current cost estimation method at IHC is a top-down price-to-win analogy cost estimation. This method uses mainly the weight of the ship as an input variable for the...
