BAR Technologies (BARTech) has been awarded a full Type Approval Design Certificate (TADC) for its wind propulsion technology – BAR Technologies WindWings by Yara Marine Technologies (WindWings) – from classification society DNV.

Since being awarded an approval in principle (AiP) for WindWings in 2021, inventor and designer BARTech and industrialisation partner Yara Marine Technologies (YMT) have focused on progressing the WindWings design through to the next level of DNV certification.  This has involved validating WindWings design compliance with full detail on construction, loading analysis, the use of materials and the supporting technical systems and their redundancy.

With TADC now granted for WindWings, there is a clear route forward for the technology to be installed on any DNV-classed vessel, either as a retrofit or on newbuilds.

“Securing TADC is a key milestone for the evolution of WindWings technology, as we move towards installation on the vessel Pyxis Ocean,” says Lauren Eatwell, head of WindWings, BAR Technologies. “Working closely with our project partners and DNV has ensured that while it’s been a long journey to TADC, our patented technology is now in a position for rapid roll out to support fleet emissions reduction.”

The installation on Pyxis Ocean, an 81,000dwt Kamsarmax owned by MC Shipping and chartered by Cargill, will be closely followed by installation on the Berge Olympus, a 211,200dwt Newcastlemax owned by Berge Bulk, according to Eatwell.

“These vessels will be the first of many to enjoy fuel savings of approximately 1.5tonnes of fuel per WindWing per day on an average worldwide route, and therefore reduced CO2 emissions of some 4.65tonnes per WindWing per day,” she says.
