Soft Sails Technology Introduced for Wind-Assisted Bulk Carriers

Japan’s Orix Corporation and Sumitomo Heavy Industries are collaborating on a new project to explore the feasibility of using soft sails for wind-assisted propulsion on a larger bulker ship. This innovative approach to wind-assisted propulsion for commercial vessels represents a departure from traditional methods that have focused on solid sails, wing foils, and rotors. North Sails Japan, renowned for producing high-quality soft sails used in competitive sailing events, is developing a furling sail made of UltraPE (Dyneema) laminated cloth for testing on one of Orix’s existing vessels.

Sumitomo Heavy Industries and North Sails Japan are responsible for designing the wind-assisted propulsion system, including the soft sails, and analyzing operational data during the demonstration. Orix will oversee the installation of the soft sail and gather fuel efficiency data while the sails are in use. The energy-saving benefits of the soft sails will be calculated based on the data collected during the experiment. The wing-shaped soft sails, constructed from advanced polyethylene fiber fabric, will be mounted on the bulker’s derrick post to harness wind power for propulsion.

The soft sails, measuring approximately 26 feet in height by 43 feet in width, can be adjusted to optimize performance based on wind direction. While the exact number of sails to be installed may vary, the companies aim to enhance the fuel efficiency of existing vessels and expand their understanding of wind-assisted propulsion technology through this feasibility study. By advancing efforts to apply this innovative system, they seek to contribute to sustainable shipping practices and reduce environmental impact in the maritime industry.
