Certificates for Anemoi and Econowind

In a sector as capital-intensive as shipping, obtaining the necessary certificates is an absolute necessity. Two companies have received their certificates for their development. This enables investors to embrace these developments with confidence. Shipping companies can thus make informed choices in favour of CO₂-free shipping.

Anemoi Gets Wind in its Sails with Latest Bureau Veritas Certification

Anemoi Marine Technologies has secured design assessment certificates from Bureau Veritas covering several versions of its Rotor Sail wind-assisted propulsion technology, expanding third-party certification of its product range. The approvals cover the company’s fixed and rail-deployed 3.5-metre by 24.5-metre Rotor Sails, including explosion-rated (EX-rated) versions and shorter variants designed for vessels operating under air draft restrictions. Applications are also being progressed for fixed and folding 5-metre by 35-metre Rotor Sails.

Anemoi said its entire Rotor Sail portfolio is now covered by approvals from Bureau Veritas, Lloyd’s Register, DNV, ABS and ClassNK, providing shipowners and operators with independent validation of the technology and helping reduce project risk for both newbuild and retrofit installations. The company added that its Rotor Sails are already operating on vessels classed by multiple classification societies across a range of vessel types and operating conditions.

“These latest approvals highlight how Anemoi is advancing in both technical maturity and scale of deployment, while continuing to focus on easing implementation for ship owners. Verification from Bureau Veritas and several other class societies is a crucial pillar for building confidence in Anemoi’s solutions, further driving the uptake of wind-assisted propulsion across the global market.

DNV approval clears path for wider VentoFoil rollout

Dutch wind propulsion specialist Econowind has received a Type Approval Design Certificate (TADC) from classification society DNV for its VentoFoil 3-Series wind-assisted propulsion system, removing a key hurdle for installation on DNV-classed vessels. The approval confirms the 16 m suction wing complies with DNV’s ST-0511 standard for wind-assisted propulsion systems, allowing shipowners and shipyards to integrate the technology without repeating a full design assessment for each project. The certification is expected to speed up both retrofit and newbuild installations as demand for wind-assisted propulsion continues to grow under tightening emissions regulations and rising fuel costs.

Chiel de Leeuw, chief commercial officer at Econowind, said the approval would simplify deployment across DNV-classed fleets. “This TADC gives DNV-classed shipowners confidence that VentoFoils meet the highest industry standards. It simplifies the approval process for both retrofits and newbuilds,” he said.

The VentoFoil 3-Series is Econowind’s most widely deployed product, with more than 150 units sold. The system uses boundary layer suction technology to generate additional forward thrust from the wind, reducing fuel consumption and helping owners lower FuelEU Maritime compliance costs. Designed for both retrofits and newbuildings, the system features a tilting foundation that allows the wings to be lowered during port operations or adverse weather.
