As explained, the initiative named as ‘Decade of Wind Propulsion’ goals to achieve a rapid and measurable decarbonisation of the global shipping fleet in the 2020s.

What is more, the association noted that wind propulsion systems help ship owners and operators reduce carbon emissions by up to 30% for retrofit solutions and significantly higher for optimised newbuild ships.

"It’s clear that wind must be fully integrated into the decarbonisation pathways for shipping - it is an abundant, widely available and free energy source waiting to be harnessed."

....Gavin Allwright, IWSA Secretary General, noted.

For the record, there are already 11 large ocean-going vessels with wind-assist systems installed, with over 20 rigs installed along with two more installations pending this quarter and a further 20+ smaller sail cargo and small cruise vessels using wind.

In addition, the campaign will focus on three major factors:

  1. Delivery: The strong pipeline of retrofit systems and newbuild projects suggests that numbers will double each year going forward – the IWSA expects that over 40 large wind propulsion equipped vessels will be operating by 2023.
  2. Optimisation: R&D to improve optimisation of existing systems continues apace alongside new concepts and solutions. IWSA is launching a ‘Wind Propulsion Accelerator Programme’, which has a dedicated test fleet, an incubator programme to support wind technology and a pipeline to assist bringing these systems to market. The optimisation strategy includes research in hybrid systems that fully integrate the energy management vessel from ship design to advanced weather routing and other aspects, which enable the full benefit of wind to be realised.
  3. Facilitation: The adoption of a hybrid W.A.V.E. - Wind propulsion with Activity - operational optimisation (speed, power limits, weather routing etc); Vessel optimisation (EMS integration, energy efficiency measures etc.) to significantly reduce the amount of Eco fuels required, thus enabling a quicker, deeper and ultimately cheaper roll out of these new fuels into the market. Less storage space, the increase of vessel range and even the potential to generate fuel onboard are further key facilitators.

"This initiative represents a redoubling of our efforts to accelerate the number of commercial shipping installations and a determined drive to create a level playing field in all policy decarbonisation pathways and regulatory frameworks internationally."

...as ISWA stated.

Concluding, the International Windship Association (IWSA) facilitates and promotes wind propulsion for commercial shipping worldwide and brings together all parties in the development of a wind-ship sector to shape industry and government attitudes and policies.
