1. Project Overview

Project Background

Fishing fleets operating ocean-going out of Sanya face rapidly changing marine meteorological conditions. Strong winds, severe convective weather and sea fog pose direct threats to navigation safety and fishing operation efficiency. Traditional weather assessment relying on human experience suffers from significant errors and data lag, failing to provide real-time accurate meteorological parameters including sea surface wind speed & direction, temperature, humidity and visibility. The fleet required a reliable integrated onboard meteorological monitoring system capable of withstanding highly saline and humid offshore environments.

Qingdao Hotech Automation Technology Co., Ltd. undertook the meteorological equipment renovation project for this ocean-going fishing vessel. We delivered a customized complete onboard weather monitoring solution, covering on-site equipment installation, commissioning and full data docking.

Project Location

Ocean-going fishing vessel based in Sanya, Hainan Province

Project Executor

Qingdao Hotech Automation Technology Co., Ltd.

(All products hold marine certification and have been installed and delivered onboard vessels)

2. Key Project Pain Points

1. Harsh marine operating environment: High salt fog, high humidity and extreme temperature fluctuations at sea lead to frequent corrosion and breakdowns of ordinary civilian meteorological sensors.
2. Special vessel working conditions: Constant hull sway and navigation vibration demand shock-resistant and anti-toppling mounting structures for all equipment.
3. Comprehensive monitoring requirements: The system must simultaneously measure wind speed, wind direction, air temperature, relative humidity and sea surface visibility.
4. Real-time data transmission: Monitored data requires local storage and real-time display on shipborne terminals, enabling captains to judge sea conditions and optimize fishing routes promptly.
5. Compact installation layout: Limited deck space calls for an integrated single-pole design that minimizes footprint and simplifies installation.

3. Hotech Customized Solution 

A full set of Hotech professional onboard meteorological hardware is mounted on an integrated pole, consisting of multiple specialized sensors:

1) Cup Anemometer & Wind Vane

Engineered to withstand severe sea wind impacts, it delivers precise real-time readings of instantaneous and average wind speed and direction. It enables early warning of sudden gusts to prevent vessel capsizing and fishing gear damage.

2) Infrared Forward-Scatter Visibility Sensor

Measures visibility during foggy or rainy offshore conditions and triggers early low-visibility alarms to mitigate collision risks in nearshore waters.

3) Radiation-Shielded Temperature & Humidity Sensor

Adopts a double-layer ventilated anti-radiation louver housing to block direct sunlight and seawater splashes, capturing accurate ambient temperature and humidity readings for sea fog and rainfall prediction.

4) Integrated Anti-Corrosion Mounting Pole

Marine-grade hot-dip galvanized and plastic-sprayed pole with outstanding salt fog resistance. Modular layered brackets are fitted with fully waterproof sealed cable joints to support long-term vessel operation at sea.

5) Supporting Data Acquisition & Control Cabinet

Deck-mounted central control unit aggregates data from all sensors with local real-time storage. It connects to display terminals in the wheelhouse, allowing captains to view complete meteorological data from the cockpit.

4. On-Site Project Implementation

1) On-Vessel Survey & Position Matching

Hotech field technicians boarded the vessel to survey deck installation zones. We selected unobstructed, airflow-neutral positions clear of masts and railings to guarantee accurate meteorological data collection.

2) Anti-Corrosion Reinforced Installation

Vessel-specific fasteners secure the main pole. All cable connectors receive dual waterproof and anti-salt fog sealing treatment, while shock-absorbing gaskets are fitted under sensor brackets to reduce equipment wear caused by hull vibration.

3) Full Equipment Calibration & Commissioning

Post-installation, technicians calibrate wind sensors, visibility detector and temperature-humidity probes one by one. Data acquisition terminals are fully debugged to ensure stable, low-latency data transmission without packet loss.

4) Crew Operation Training

We provided hands-on training for captains and crew covering real-time data viewing, routine simple maintenance and basic troubleshooting guidelines for extreme sea conditions, alongside printed operation manuals.

5. Project Outcomes & Customer Benefits

All-in-one real-time marine meteorological monitoring

The integrated system delivers complete wind, temperature, humidity and visibility data in one unit, supporting captains to make scientific adjustments to navigation and fishing schedules.

Robust weather resistance for harsh ocean environments

Fully waterproof, anti-corrosion and shock-resistant construction reliably withstands high salt fog and heavy sway during Sanya offshore and deep-sea voyages, drastically cutting long-term maintenance and replacement costs.

Enhanced safety for ocean fishing operations

Early data alerts for gales, dense fog and other hazardous weather eliminate navigation risks and reduce safety hazards for fisheries production.

Space-saving integrated design without disrupting deck operations

The centralized single-pole layout occupies minimal deck area, leaving ample room for fishing gear and crew passage, perfectly fitting medium and small ocean-going fishing vessels.

Traceable historical meteorological data

Continuous local data storage allows the fleet management team to export historical meteorological records for long-term sea area climate analysis, optimizing annual fishing voyage planning.

6. Client Testimonial

Fleet Manager, Sanya Fishing Vessel Team:

“Sudden severe sea conditions are our biggest worry on long-distance voyages, and weather judgment based purely on experience is unreliable. After Hotech’s onboard weather station was installed on our vessel, the deck monitoring system runs stably without failures even under heavy salt fog and strong winds. The wheelhouse receives accurate real-time wind and visibility data, greatly boosting our sense of safety at sea. The installation process was streamlined, and their after-sales technical team provided professional on-site commissioning and training.”

7. Extended Hotech Service Offerings

Qingdao Hotech Automation provides customized full-set monitoring solutions for all types of vessels including ocean-going fishing boats, inshore fishing craft, marine patrol vessels and yachts. Our product portfolio covers onboard weather stations, wind LiDAR, deck environmental monitoring systems and CTD (Conductivity-Temperature-Depth) detectors.

We deliver one-stop services including site survey, equipment supply, on-site installation & commissioning, and lifelong technical maintenance, supporting vessel renovation projects at coastal ports nationwide.
