DIMAR (Colombia's National Maritime Authority) continues to invest in the safety of its waterways and ports. The most recent project completed was the renewal of the Aids to Navigation in the access channels to the Ports of San Andrés and Providencia located in Colombia's Caribbean waters. According to local sources “This is an investment that impacts decisively in maritime future and economic development of Colombia's Caribbean islands".

The works have been carried out by Almarin, specialist in the manufacture and installation of floating aids to navigation. The scope of the project included the supply, delivery and deployment of more than thirty buoys: twenty lateral marks, one safe water mark and one isolate danger mark in the access channel to the port in San Andrés island, and also eight lateral buoys and one safe water mark in the access channel to the port in Providencia island.

All the buoys, from Guia W range, are equipped with a closed cell polyethylene foam hull and a stainless steel superstructure. This "W" tower offers a series of advantages over the market, such as improved daytime visibility, increased safety for the technician working on board, a longer lifetime and minimum maintenance.

The buoys have been equipped with M860 self-contained lights with data telemetry provided by satellite communications. This capacity to monitor the position and status of the buoys in any place of the country without depending on ground infrastructure is a key operational benefit for DIMAR. Each buoy reports its status at fixed time intervals and if there is any exceptional event the port managers will be sent an alert by e-mail or SMS.

This project has been carried out by Almarin with the collaboration to local experts Iner Consultores and Cenacol, this last company in charge of the installation. In 2013 DIMAR began the improvement of Colombia's aids to navigation with the renewal of Buenaventura and Cartagena ports, also carried out by Almarin.
