High-Precision Gyro Navigation System Upgrade for Seabed Cleaning Vessel

Background:
An aging seabed cleaning vessel had a completely failed navigation system, making it impossible for the hydrographic computer, ship control system, and charting system to obtain accurate positioning and heading information. The lack of precise navigation severely affected operational efficiency and posed potential safety risks.

Customer Requirements:

• Replace the fully failed gyro navigation system

• Ensure full compatibility with existing hydrographic measurement and control equipment

• Provide real-time, precise positioning and heading data

• Include installation, calibration, and on-site operational training

• Urgent delivery to ensure the vessel can resume operations quickly

Solution:
Our engineering team deployed a high-precision fiber optic gyro (FOG) navigation system integrated with a GPS module, delivering precise navigation and seamless data integration. Key features include:

• Plug-and-play installation: Rapid setup with automatic calibration, minimizing commissioning time and operational downtime

• Strong system compatibility: Fully compatible with existing ship control and hydrographic measurement systems, requiring no additional modifications

• High precision and stability: FOG delivers accurate heading and positioning, maintaining stable performance at high speeds and in harsh marine conditions

• On-site training: Engineers provide hands-on training for operators, covering system operation, calibration procedures, and basic maintenance

• Logistics support: Coordinated with the customer’s chosen freight partner to ensure safe and timely delivery of the navigation system and spare parts

Results:

• Restored operational capability: The vessel regained stable and precise navigation, enabling efficient seabed cleaning operations

• Reliable real-time data output: High-precision, real-time information provided to the hydrographic computer and charting system

• Reduced risk and downtime: Quick installation, automatic calibration, and hands-on training minimized operational interruptions

Technical Highlights:

• High-precision three-axis fiber optic gyro

• Integrated GPS for improved positioning accuracy

• Automatic calibration, plug-and-play installation

• Full compatibility with hydrographic measurement and control systems

• Stable and reliable performance under high speed, high shock, and harsh marine environments

Conclusion:
This case demonstrates our capability to provide high-precision, turnkey navigation solutions for older marine platforms. By integrating fiber optic gyros with GPS, combined with on-site training and rapid deployment, we helped the customer quickly restore vessel operational capability, ensuring reliable and efficient seabed operations.
