As a continuation of the project to renew the maritime signaling in the Broa de Sanlúcar, Almarin has just supplied and installed four buoys at the mouth of the Guadalquivir. These buoys are part of the Guia W range, which is characterized by its stainless steel frame and elastomer float. In addition to these four buoys, Almarin has installed another buoy for the beacon called Caridad, located at the height of La Puebla del Río, whose mission is to mark the limit of the navigation channel in the curved section near this town.

This new type of buoys not only minimizes maintenance tasks, with consequent cost savings, but also improves daytime visibility, increases personnel safety and is better adapted to the particular current and wave conditions, which sometimes they are very hard at the mouth of the Guadalquivir, between Sanlúcar de Barrameda and Chipiona. The new model of buoys represents an environmental improvement, since no oxides will be produced in the buoys, it will not be necessary to paint them and the duration of the chains will be longer since the weight of the buoys has been considerably reduced. Maritime safety is also improved thanks to the synchronism of the new projectors with high-power LED technology and the AIS-AtoN systems that allow the navigator to know the position of the buoy in real time.

Since 2015 the Seville Port Authority has been renovating the maritime signaling of the Broa de Sanlúcar, consisting of twenty buoys at the mouth of the Guadalquivir river, through the replacement of steel buoys by elastomer buoys. This has been carried out in accordance with the recommendations of the International Association of Aids to Maritime Navigation and Lighthouse Authorities (IALA). Almarin, an industrial member of IALA since 2008, was the company in charge of carrying out this renovation for a total of sixteen new elastomer buoys. In addition to the Chipiona lighthouse, more than 130 lights made up of buoys, beacons and leading lines help the navigator on his way from the coast to the Port of Seville.

From Lindley Group we build piers to open new leisure spaces in natural locations. The piers are made of materials that adapt to their environment, either with a wooden structure in a quieter setting or with a metal structure designed for more demanding conditions, such as one designed for boarding passengers.
