Developing Next Generation Wind Assist Technology to Improve Fuel Efficiency

Focus Area: Maritime Green Technologies

Overview

Wind Assist Ship Propulsion (WASP) technologies are being revisited, with various wind sail innovations for ships gaining attention. The IMO has recognized these technologies as key to reducing fuel consumption and emissions. How can we develop next-generation wind assist technology to meet modern requirements?

Importance

  • WASP technologies, such as Flettner rotors and kite sails, offer renewable energy for commercial shipping routes.
  • Many concepts are still in early stages and have not reached sufficient technology readiness levels for widespread adoption.

Market Potential

  • Applicable to both new and existing ships, the market is expected to grow from USD 300 million annually in this decade to USD 2.5 billion annually by the 2050s.

Current Efforts

  • Various solutions like Flettner rotors, rigid sails, and kite sails are in different development stages.
  • Control systems use weather data and AI modeling for optimal operation.

Solution Criteria

  • Must work in diverse wind conditions and weather patterns.
  • Compact enough to fit on various vessel types.
  • Must be retractable to avoid collisions with port structures or bridges.

Potential Solutions

  • Effective sail designs suitable for different vessel types.
  • Maximize wind power with minimal crew intervention.
  • Easy installation during drydocking for retrofits.

These solutions will enhance fuel efficiency and environmental sustainability, supporting a transition to cleaner and cost-effective shipping technologies.
