Astander is part of the consortium of the W1NDSAIL project, which focuses on the industrial research and development of a new wind-assisted propulsion system for ships. The project aims to improve the efficiency, sustainability, and competitiveness of rigid suction sail technologies (eSAIL) through aerodynamic optimization, lightweight materials, and advanced manufacturing processes.
The main objective of W1NDSAIL is to develop a new generation of wind-assisted propulsion systems based on rigid suction sails, capable of reducing fuel consumption and greenhouse gas emissions by over 40%. The project includes the design, prototyping, and testing of large-scale eSAIL unit (22–36 meters high), as well as the integration of these systems into real vessels.
Advances in maritime sustainability have led to the development of innovative wind-assisted propulsion systems for ships. In this context, the W1NDSAIL project, led by ASTANDER, bound4blue, DEGIMA, and Laulagun Bearings, represents a major step forward in the decarbonization of maritime transport.
The project focuses on the research and development of rigid suction sails (eSAIL), a high-efficiency wind propulsion technology designed to reduce fuel consumption and greenhouse gas emissions by over 40%. These sails are compact, lightweight, fully electric, and require minimal maintenance. They are suitable for vessels with limited deck space and do not rely on hydraulic systems, making them ideal for retrofitting and new builds alike.
The W1NDSAIL system integrates advanced aerodynamic control through suction-based boundary layer management, enabling lift coefficients up to 6.5, four times higher than conventional sails. The project includes the design and prototyping of sails between 22 and 36 meters in height, making them the largest suction sails developed to date.
