Mavi Deniz’s marine systems operation provides “Steel” Navigation Buoys or “resilient polyethylene foam” Navigation Buoys in a wide range of diameters and net buoyancies. The buoy bodies can be supplied on their own or with the addition of navigation equipment, including but not limiting to beacons, solar powered or dry cell batteries, radar reflectors — a complete range of IALA compliant, low maintenance, robust buoys from 1.25 to 3.6m diameter and providing a realistic alternative to traditional steel buoys. These modular buoys are lighter, easily transported, less maintenance and can be deployed using smaller support vessels. The Hull sections and superstructure are manufactured from ‘UV’ stable, Virgin Polyethylene. The superstructure is made using a unique, ‘twin skin’ construction technique while the Hull sections are filled with water resistant foam which prevents sinking. The Hull sections are fitted around a fully integrated, HDG steel core incorporating both mooring and lifting eyes. The flat base design ensures that the Buoys are easily stored upright and also adaptable to ‘dry out’ situations. The hull sections are also resistant to impact and provide a limited ‘self-fendering’ position.

Our new designed UHMWPE Navigation Buoy is a cost-effective, long life and environment-friendly.  The UHMWPE float could absorb the collision force maximally, which will be efficiently helping the buoys to be spring back without deformation. With great resilience, stretch resistance, the UHMWPE material is hard to tear, the UHMWPE float could absorb the collision force maximally, which will be efficiently helping the buoys to be spring back without deformation. There is a unique steel structure supported inside the buoy, and high-density polyurethane foam filled to give strong support to the floats, which will keep the high strength and excellent sealing of the buoy. The superstructure is anti-corrosion treated, and it service life could be more than 20 years;  The mooring eyes and lifting eyes are specially designed, and their breaking load could reach 60 tons. International Association of lighthouse authorities was formed to unify the world’s buoyage system. Our Navigation Buoy developed for IALA systems. The IALA systems are made up of five types of buoys, lateral,  cardinal surface water, hidden danger, and individual. The IALA buoyage system is split into two regions A and  Bo
