Analysis on the Development of Wind-assisted Ship Propulsion Technology and Contribution to Emission Reduction

Abstract

With the issue of peaking carbon dioxide emissions and carbon neutrality increasingly becoming the forefront of international public opinion, changes in the shipping industry are imminent and destined to cause long-term transformation across the entire industry chain, from ship design to maritime operations. Wind energy as a clean energy source has attracted the increasing attention of experts in the shipping field. This paper summarizes the application and development of wind-aided navigation technology for ships represented by rotors, towing kites, wing sails and soft sails, and analyses the constraints of wind-aided navigation technology. The contribution to emission reduction of typical wind-aided navigation methods such as rotors, towing kites, wing sails and soft sails is summarized. Finally, the development suggestions of wind-assisted ship propulsion (WASP) technology are summarized and proposed, which can provide reference for further research and application of this technology.

Fluid Dynamic Simulation of Sail Design Performance on Sail-Assisted Ship; A Preliminary Study

“…The Sail-assisted ship is one of the green technologies that utilize wind thrust. Ship propulsion is assisted by the wind, according to research conducted by [11]- [13] has the potential to reduce the level of fuel consumption and carbon emissions generated in shipping. Nyanya et al [11] said that when a ship sails at an optimal sail angle and optimal deck area, the potential for reducing CO2 emissions is 36% compared to ships without the intervention of sailing technology innovation.…”

Analysis of Dynamic Characteristics of Rotor Sail Using a 4DOF Rotor Model and Finite Element Model

“…CCSs (Carbon Capture Systems) and Air Lubrication are considered realistic alternatives to reduce fuel consumption and greenhouse gas emissions in existing ships [7][8][9]. Additionally, a wind-assisted ship propulsion device that can be added onto existing vessels, 2 of 22 called Wind-Assisted Ship Propulsion (WASP), is also being developed [10][11][12]. Among the WASP options, the Flettner rotor is considered the most realistic solution [13][14][15].…”

“…Anemoi installed 16 m high and 2 m diameter rotor sails on a 64,000 DWT (deadweight tonnage) Ultra-Large Bulk Carrier for operation. Additionally, Norsepower developed a 30 m height and 5 m diameter rotor sail in 2018, which was installed on the Maersk Pelican vessel [11].…”
