Nanotechnology contributes to marine safety through the development of advanced materials and systems. For example, nanocomposites used in life-saving equipment, such as life jackets and lifeboats, offer better buoyancy and durability. Additionally, nanotechnology-enhanced coatings can be applied to firefighting equipment and vessels to improve fire resistance. Furthermore, nanosensors integrated into critical ship systems can provide early warnings of potential failures, enhancing overall safety at sea.
