The International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA) will hold its prestigious quadrennial IALA Conference from 27 May to 2 June in Incheon (Republic of Korea).

Almarin, an IALA industrial member, will exhibit and present its latest development in marine aids to navigation for the marking of rivers. This innovative buoy (illustrated), which works as a fixed and floating mark, is designed for rivers or channels with a large amplitude of water level variation while maintaining a high precision when water levels are low. It has been developed by Almarin in conjunction with the Port Authority of Douro e Leixões (APDL) and Instituto Hidrográfico de Portugal.
