Have you ever wondered why areas like swimming zones, mooring stations, or restricted zones in the open sea are clearly marked and easy to identify? The answer lies in the use of marine buoys – essential floating devices designed to ensure safety and guide water traffic. A marine buoy not only helps indicate boat docking points and mark safe swimming areas but also acts as a "soft barrier" between humans and underwater risks. As safety regulations grow increasingly strict, choosing the right type of internationally certified marine buoy is becoming a top priority for companies in marine transportation, coastal tourism, and aquaculture. Join SIAM Brothers Vietnam in exploring everything you need to know about marine buoys — from definitions and real-world applications to technical specifications — in this latest 2025 update.
1. What is a Marine Buoy?
A marine buoy is a floating device used to mark waterways, signal danger zones, or pinpoint the location of offshore structures. At SIAM Brothers Vietnam, our marine buoys are manufactured using high-quality HDPE combined with PES and foam-filled interiors. With standard dimensions of 1200mm x 800mm x 550mm and buoyancy of up to 450kg/m², these buoys are ideal for floating structures like docks, riverfront restaurants, or aquaculture cages.
Our marine buoys are UV-resistant, waterproof, and built to endure harsh weather conditions — ensuring long-term performance and cost-efficiency.

3. Technical Standards and International Regulations for Marine Buoys
3.1. IALA Maritime Buoyage System
- The IALA Maritime Buoyage System, established by the International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA), is currently applied in most coastal countries worldwide.
- This system is divided into two regions with distinct rules for buoy colors and vessel navigation directions:
- Region A: Covers Asia, Europe, and Africa.
- Region B: Covers North America, South America, and parts of the Pacific.
- Marine buoys must be installed with correct color schemes, shapes, and lighting signals according to each region’s regulations.
3.2. Compliance with Vietnam’s National Technical Regulations (QCVN)
In Vietnam, the production, installation, and use of marine buoys must follow the regulations set by the Ministry of Transport, especially:
- QCVN 39:2019/BGTVT – National technical regulations on maritime signaling.
- Specifies detailed requirements on dimensions, colors, signal light intensity, wave resistance, and construction materials.
- Installation units must be qualified, licensed, and subject to periodic quality inspections.
3.3. Material and Durability Standards
- Marine buoys must be made of materials that can resist corrosion, UV radiation, and saltwater environments. The most widely used material is virgin HDPE combined with a high-buoyancy foam core — offering lightweight construction, durability, and strong impact resistance.
- Marine buoys with integrated lights must meet IP standards for waterproofing, dust resistance, and mechanical strength.
3.4. Load-Bearing Capacity and Mooring System
- To ensure stability against waves and strong currents, marine buoys must:
- Be designed with buoyancy suitable for the structure (e.g., ≥ 450kg/m² like SIAM Brothers’ buoys).
- Include a secure mooring system using galvanized steel cables, heavy-duty chains, or concrete anchors fixed to the seabed.
- Be impact-resistant and remain structurally sound without deformation or leakage after extended use.
Why Follow International Standards When Using Marine Buoys?
- Complying with international standards ensures consistent signaling across global waters, reducing the risk of confusion and maritime accidents.
- For businesses, using marine buoys that meet IALA and QCVN standards enhances credibility and facilitates approval in inspection, handover, and offshore project implementation processes.
