Rotomoulded polyethylene mooring buoys for aquaculture mooring legs, harbour berthing points and navigation marking. Each buoy is moulded as a single piece from UV-stabilised virgin polyethylene at our İzmir facility; the internal cavity is filled with closed-cell foamed polyurethane or polystyrene. The buoy stays afloat even when punctured. Metal hardware is hot-dip galvanised; the central chain passage and colour-marking are delivered to IALA recommendations. ASAKUA is an IALA member.
Buoyant load balancer and surface marker on the mooring leg running from seabed anchor to the surface in open-ocean cage systems. MB1200–MB4000 larger models distribute anchor load, limit cage movement and give the operator a visible reference on the leg.
Mooring point for vessel berthing in marinas, sheltered bays and harbours. MB600 and MB900 are the typical selections; the central chain passage channel is compatible with standard mooring hardware.
Direction buoy on harbour channels, river mouths and shallow water hazards, marked to IALA colour and lateral-system rules. Optional solar LED flashing lantern can be integrated for night visibility and operational continuity.
The buoy body is rotationally moulded from UV-stabilised virgin polyethylene as a single piece. This process leaves no seams, welds or joints — critical for long-term performance in aggressive marine conditions. Eight standard models span MB300 to MB4000: diameter 900–1,600 mm, height 900–2,500 mm, volume 300–4,000 litres, mooring load 150–2,000 kg.
The full internal cavity is filled with closed-cell foamed polyurethane or polystyrene — the buoy stays afloat even after the body is punctured. The central tarred-chain passage distributes mooring load evenly into the body and speeds up rigging on site. Steel hardware (top and bottom rings, connection fittings) is hot-dip galvanised.
Day-mark colouring is applied to IALA recommendations depending on the use case; an optional solar LED flashing lantern can be integrated at the buoy top. Buoy selection requires weight of mooring equipment, accessories to be installed and the focal height required above water — all evaluated together. ASAKUA supports product selection and on-site rigging; as an IALA member we track marine aids to navigation standards.
