Over the years, Globeco has also developed considerable know-how in the field of maritime signalling. On behalf of the Ministry of Environment from 1998 to 2000, Globeco has designed, supplied, installed and carried routine and special maintenance for maritime signalling systems made up of buoys fitted with solar panel marine lights. These systems were for the "A" zone of the following protected marine areas: Isole di Ventotene and Santo Stefano; Tavolata - Punta Coda Cavallo; Cinque Terre; Porto Cesareo; Punta Campanella. Then from 2001 to 2003, Globeco, on behalf of "Ente Romanatura", carried out a maritime signalling system for the delimitation of the "A" zone of the protected marine area of "Secche di Tor Paterno" on the Lazio coastline.
