Bureau Veritas has granted approval in principle (AIP) to Ponant for its innovative sailing passenger vessel concept, Swap2Zero. This 186.2-meter vessel is designed for transoceanic voyages with close to zero emissions, focusing on energy efficiency, sobriety, and the optimized use of renewable resources. The primary method of propulsion is wind, complemented by solar power, hydrogen fuel cells, and renewable fuels like bio and e-methane. The Swap2Zero project boasts features like up to 50% wind-assisted propulsion, one month of operational autonomy, and the ability to operate for 15 days without wind at 10 knots speed. It incorporates 1,000 square meters of solar panels, PEM and SOFC fuel cells, batteries, and renewable liquid hydrogen. Additionally, dual-fuel engines certified for biodiesel and biogas ensure compliance with safety regulations. Noteworthy components include an advanced carbon capture system to store CO2 emissions, waste heat and cold recovery systems, contributing to sustainability. The AIP aligns with conventions like SOLAS, ILLC, MARPOL, and the IGF Code, meeting Bureau Veritas' rules for ship classification, wind propulsion systems, and hydrogen-fueled ships. Ponant's Swap2Zero sets a new standard in eco-friendly maritime innovation.
