Modern ships that capture solar energy and wind like Viking ships are making a comeback, raising questions about their efficiency compared to traditional steel cargo vessels.
Modern ships designed to harness solar energy and wind, reminiscent of Viking vessels, are making a resurgence, prompting a reconsideration of using sail technology in contemporary maritime practices. The pressing issue is whether advanced techniques available in the 21st century are capable of effectively utilizing this age-old navigation skill alongside the mammoth steel cargo ships that dominate global shipping.
The maritime industry is experiencing a shift as new technologies push for a revival of sustainable sailing practices, particularly in the Baltic Sea. Companies like Sweden's Alfa Laval and shipping group Wallenius Lines are at the forefront of this transformation, having established a joint venture named Oceanbird in 2021. Their goal is to innovate traditional shipping methods, and they now boast a significant milestone with the first order for their sail technology, Wing 560, signaling a tangible step forward in integrating sails into modern shipping.
This development carries important implications not only for the shipping industry but also for environmental sustainability. As shipping accounts for a considerable portion of global emissions, incorporating sail technology could represent a vital shift toward greener practices in maritime transport. The return of large sailing vessels, if successfully implemented, could set a precedent for future developments in eco-friendly shipping solutions, encouraging further investments in renewable maritime technologies.
