Product Description

Our customers spoke, and we listened. Previous iterations of this style of buoy were constructed out of one piece the internal hardware, radar reflector, & concrete ballast all stuck together in the same unit. Any significant damage to the buoy meant it had to be completely replaced. End of life recycling posed a challenge as the internal parts were difficult to separate. The new TDL 1500 pillar buoy comprised of modular hull, tower, and frame sections – enabling components to be replaced on site as opposed to needing a complete removal and re deployment of a new unit. The TDL 1500 has high mooring capacity, high visibility, and exceptional stability. The bilge keel legs are hydrodynamically designed to keep the buoy stable and properly oriented in high currents. The legs also provide an exceptionally stable base for the buoy to stand upright in transport, maintenance, and storage. The hot-dipped galvanized frame provides a 21,772 kg / 48,000 lbs lifting break load with minimal stress to the buoy shell. An optional internal radar reflector is available to further improve buoy detection. The TDL 1500 is available in can or conical shapes. Tidal Marine & Northwest Plastic Ltd.’s 40+ years of buoy design and manufacturing design have enabled us to take a leap forward in buoy innovation and design with the TDL 1500 – we hope you are as excited about it as we are!
