DX300-SMART

3-meter smart buoy combining navigation safety and real-time ocean monitoring

System Overview

This new-generation intelligent buoy combines the advantages of channel navigation buoys and oceanographic observation buoys, achieving both navigation safety and data acquisition in a single system.
The complete system consists of:

• Monitoring Platform (remote data access and control)
• Internal Equipment Bay (power and electronics)
• Underwater Instrument Well (for ocean sensors)
• Anti-Theft Hatch
• Mooring System
• Navigation Components (lantern, topmark, radar reflector)

Compliance Standards

The buoy design and fabrication comply with the following national and industry standards:

• Rules for Classification of Mobile Offshore Platforms (2020, CCS)
• Rules for Classification of Steel Sea-Going Ships (2018, CCS)
• Rules for Materials and Welding (2015, CCS)
• JT/T 760-2009 — General Technical Conditions for Buoys
• JT/T 761-2009 — General Technical Conditions for Aids to Navigation Lanterns
• GB 4696-2016 — Aids to Navigation for Chinese Sea Areas
• GB/T 549-2017 — Welded Anchor Chains
• GB 553-1983 — Chain Laying, Painting and Marking
• HY/T 143-2011 — Small Ocean Environment Monitoring Buoys

Key Features & Design

The intelligent buoy leverages the stable and secure station-keeping characteristics of traditional navigation buoys while integrating modern meteorological and oceanographic monitoring capabilities.

Navigation Components

• Marine lantern, tower frame, daymark, night vision lantern, and buoy body meet all AtoN standards.

Meteorological Instruments

• Top platform supports installation of multiple sensors, including:
  • Wind speed & direction
  • Temperature & humidity
  • Air pressure
  • Visibility
  • Camera & AIS antenna

Oceanographic Instruments

• Bottom-mounted instrument well accommodates:
  • ADCP (Acoustic Doppler Current Profiler)
  • CTD (Conductivity, Temperature, Depth) and other sensors
• Enables long-term, high-accuracy data collection in complex sea conditions.

Structural Design

• Buoy diameter: 3 m
• Float body: rotationally molded LLDPE with EPS foam core
• Frame: marine-grade stainless steel
• Lantern tower: conforms to HF2.4 m channel buoy standard
  • Draft: 2 m
  • Freeboard height: > 1 m
  • Focal plane height: > 4.5 m

Application Scenarios

The new intelligent buoy serves both as a channel navigation aid and an ocean monitoring platform.
It is ideal for:

• Harbor and channel marking
• Offshore bridge or wind farm monitoring
• Coastal research stations
• Environmental and meteorological observation

With its modular design, robust structure, and compliance with industry standards, this buoy provides a comprehensive smart navigation and data acquisition solution—enhancing maritime safety while delivering reliable ocean data in real time.
