Vertical Axis Wind Turbine Optimization for Ship Propulsion: using a free wake vortex model

The global emission of harmful greenhouse gasses has to be reduced. Commercial shipping contributes to these emissions by using fossil fuel as the only energy source to provide propulsion and power auxiliary systems. In order to reduce fuel consumption, much research is focused on increasing the efficiency of the propulsion system and reducing...

Maneuverability of Wind-Assisted Ships: A Time Domain Simulation Tool

Wind-assisted ships are installed with wind propulsors capable of generating thrust for aiding the propulsion of the ship, with the purpose of saving fuel by reducing the required propeller speed and thus engine power. Wind-assisted ships are becoming more common due to high fuel prices and rising environmental concerns. The subject of this...

Development of a sustainability impact method for Pacific inter-island maritime transport

Maritime transport represents one of the main means of product delivery and passenger transportation across the world but its impact on climate change has positioned it among the world's biggest CO2 pollutants. One of the most impacted regions in the world by maritime transport emissions is the South Pacific Region. Studies show that if climate...

Sustainable transport of polymetallic nodules

This research examines the possible pathways and available technologies that will help the shipping sector to achieve the climate goals set by the IMO. Reaching these goals will require financial incentives and policies regarding sustainability. These policies need to describe regulations at both international and regional level given the...
