Final Report – Bio-Ethanol as an alternative fuel for vessels

Many fuels are currently considered for reducing the emissions in shipping; Methanol, LNG, Ammonia, Nuclear, Biodiesel, etc. However, Bio-ethanol is not considered at all.This research looked into all aspects of ethanol in a comparison with its most closely related alternative methanol. Using a similar approach as found in earlier comparisons....

Assessment of alternative fuels for seagoing vessels using Heavy Fuel Oil

A first exploration of potential fuels for the Dutch Maritime Sector that will allow the sector to achieve the energy transition goals of 2050. A first comparison on costs of the power plants and life time fuel is made. Including, accepting a mix of green and grey fuel sources. The output is of use for anyone in the sector interested in the...

Benchmarking bulkers delivered between 2010 and 2016, identifying the effect of the EEDI introduction

The EEDI is one measure to identify the energy efficiency of a vessel. Besides EEDI there are many other aspects relevant when considering the energy efficiency quality of a vessel, most based on design insights. In this paper, a set of ten relevant indicators are identified to establish the performance of the vessel and pinpoint the source of...

Parametric modelling method based on Knowledge Based Engineering:: The LNG bunkering vessel case

This paper proposes a parametric modelling method based on Knowledge Based Engineering (KBE) for an LNG bunkering vessel (LNGBV). Parametric models aim to define the geometry and main systems configuration of the vessel starting from the principle that the vessel should be able to perform its mission successfully. The adoption of KBE in...

Fuel cell systems applied in expedition cruise ships: A comparative impact analysis

Global endeavors to reduce emissions in the shipping industry are accelerating the interest in fuel cell system. This paper explores the application of different fuel cell types (LT-PEMFC, HT-PEMFC and SOFC) in combination with different fuels (LH2, LNG, MeOH and NH3) in expedition cruise ships. The goal of this paper is to evaluate the impact...

Improved Prediction of the Energy Demand of Fuel Cell Driven Expedition Cruise Ships

Fuel cell systems require a better early-stage prediction of the energy consumption of a ship because they are more expensive, more voluminous and less able to deal with rapid load changes than conventional diesel-powered systems. This paper discusses a model for such an improved prediction of the total energy demand of an expedition cruise...

Modelling Maintenance – Cost Optimised Maintenance in Shipping

Most ship management companies base the operational cost calculation on scheduled maintenance jobs. Scheduled maintenance jobs do not take unforeseen maintenance into account. This under-estimates the operational budget. The estimation of the operational costs can be improved by including the unforeseen maintenance costs. The amount of...
