Special Issue Information

Dear Colleagues,

Nowadays, the maritime industry encounters challengeable decarbonization. The 2023 IMO GHG strategy envisages a reduction in the carbon intensity of international shipping by 40% by the year 2030; it also includes a new level of ambition relating to the zero or near-zero GHG emission technologies, zero-carbon fuels, etc. Therefore, the maritime industry also needs to be aligned with the Paris Agreement for sustainable growth. This industry is essential to prepare for the enforced GHG regulatory frameworks by using the appropriate measures with regard to low or zero-carbon fuels, energy-saving devices, engine retrofit, carbon capture and sequestration, etc. This Special Issue covers low or zero-carbon fuel bunkering, technological development, the global supply chain, and shipping optimization, along with other related topics. Studies on decarbonization, energy efficiency, GHG emissions related to Scope 3, green fuel technology, and sustainable shipping strategies are also welcome.

In order to meet current and future efforts to reduce fuel consumption and gas emissions, an increasing number of ships are being retrofitted with one of the wind-assisted propulsion solutions. In this paper, the effects of retrofitted wind-assisted propulsion on the efficiency of the propeller are investigated. The installed ship propeller is usually designed to operate under specific conditions; once the thrust force from the sails is added, the operating point of the propeller changes. Taking into consideration the reduced efficiency of the propeller, which is no longer operating in its optimal regime, the actual wind-assisted propulsion contribution can be calculated. The wind-assisted contribution is calculated with a velocity prediction program as a reduction in conventional propulsion power output by maintaining the vessel’s designed speed. From the calculated variations in sail thrust force, dependent on the wind speed, the propeller efficiency is analyzed for different operating states. The propulsion efficiency of the propeller was analyzed with a performance characteristics calculation tool that has been developed and presented in this paper. From the meteorological data obtained from Copernicus Marine Services and available ship documentation, a case study was conducted for a selected route. Full article
