Multifunctional Smart Data Buoy System for Real-Time Ocean Observation

Real-time ocean observation platform for MetOcean, water quality, navigation safety, and remote monitoring

The 3 m Multifunctional Buoy System is an integrated ocean observation platform designed for long-term marine monitoring. It combines buoy structure, sensor acquisition, power supply, alarm protection, communication, and remote data transmission into one deployable system.

Reliable marine data starts with an integrated buoy platform

For marine monitoring projects, a buoy is not only a floating body. It must carry sensors, protect electrical systems, supply power, transmit data, withstand sea conditions, and remain on station for years.

Dexonmarine designs this system as a complete offshore monitoring platform, helping project owners reduce integration complexity and improve long-term data reliability.

Real-Time Performance / Remote Controllability / Scalable Monitoring / Long-Term Deployment

What this system helps customers solve

Marine projects often face three practical problems:

• Data is delayed or incomplete
• Sensors and communication modules are difficult to coordinate
• Offshore maintenance is expensive and disruptive

This 3 m buoy system is designed to collect, process, store, and transmit marine data automatically, while allowing remote status checking, command response, and device control from the monitoring center.

A complete system, not just a buoy

Core advantages

Real-Time Performance

The data logger connects to onboard devices by cable or wireless communication, samples data at scheduled intervals, processes it locally, and uploads it to the monitoring center.

Remote Controllability

Operators can remotely start devices, adjust working schedules, check equipment status, restart programs, download data, and perform command response operations.

Scalable Monitoring

The platform can be expanded with additional sensors such as current velocity, wave height, wave period, wave direction, meteorological sensors, water quality analyzers, and camera modules.

Monitoring capabilities

Built for long-term offshore deployment

The buoy body uses a 3 m steel structure with a sealed electrical control compartment. It is designed for corrosion resistance, UV resistance, freeze-crack resistance, and long-term station keeping.

Key platform features:

• 3000 mm ± 100 mm buoy diameter
• Steel buoy body
• Maximum payload ≥ 4000 kg
• Reserve buoyancy ≥ 3 t
• Single-point full-chain mooring
• Continuous on-station time ≥ 3 years
• Average maintenance cycle ≥ 3 years
• IP67 protection rating

Intelligent electrical and data system

The buoy electrical system integrates five core subsystems:

• Observation acquisition
• Communication system
• Alarm system
• Power supply
• Data logger

The data logger manages scheduled wake-up, self-checking, data acquisition, data storage, encoding, sensor commissioning, power management, and two-way communication.

This allows the buoy to operate in a low-power automatic cycle while maintaining remote data transmission and intelligent control.

Power and communication design

The buoy uses a solar-based power supply system with battery storage and charge/discharge control. The charge controller helps prevent over-discharge, overcharge, abnormal voltage, and abnormal current conditions.

Communication options include:

• BeiDou satellite communication
• 4G / DTU mobile network
• Signal enhancement options
• Redundant data backhaul to shore-based monitoring center

This makes the platform suitable for coastal waters, inland lakes, offshore areas, and locations with limited mobile network coverage.
Why Dexonmarine

Most suppliers provide individual sensors or buoy structures. Dexonmarine focuses on system-level marine monitoring platforms.

The value is not only in the buoy body, but in how the buoy, sensors, power system, data logger, communication modules, alarm system, AIS functions, and remote platform work together.

For contractors, integrators, and project owners, this reduces coordination risk and makes the system easier to deploy, operate, and expand.
