An Expert’s View

Catriona Savage, President of The Royal Institution of Naval Architects (RINA), BMT, Programme Director, Fleet Solid Support,  highlights that naval architects play a critical role in shaping sustainable ships. “The cheapest way to implement green solutions is at the design stage,” she explains. Acting early ensures cost-efficiency while significantly cutting emissions. From rotor sails to air lubrication systems and innovative hull designs, solutions are emerging that hold immense promise for cleaner maritime operations.

However, the real challenge lies in combining these technologies to suit individual vessels and making them viable at scale. Meeting ambitious IMO emissions targets will require retrofitting existing fleets and embracing innovations in new builds. Savage notes that while progress is encouraging, much more is needed to bring these ideas from concept to application.

Collaboration and leadership, particularly from governments, are vital to achieving these goals. Savage is optimistic about the new generation of naval architects driving change. “We have young people entering the industry who are deeply focused on creating a sustainable maritime economy,” she adds. But to deliver a future-ready fleet, the time to act is now.
