Refloating and removing
the Yu Zhou Qi Hang wreck
Providing survey services to increase efficiency and safety during wreck removal and refloat operations.
In late October 2024, the heavy transport vessel Yu Zhou Qi Hang lost power and ran aground near Yeliu Cape amid Typhoon Kong-rey. Our long-time client KMS was appointed by the Taiwanese authorities to safely salvage the wreck. Brosols supported the operation with a mix of innovative monitoring systems and specialized survey services, increasing both safety and efficiency during the complex re-float.
Approach
Brosols deployed a range of survey and monitoring solutions tailored to the project’s needs:
-
Motion Sensors: In-house developed units installed on critical points of the wreck, delivering continuous vessel behavior data accessible remotely to the project team.
-
Wave Buoy: Real-time monitoring of sea state and weather risks throughout the salvage.
-
MBES surveys: High-resolution pre- and post-refloat mapping of seabed and wreck conditions. The pre-survey revealed two previously unidentified wrecks near the casualty site.
-
Pressure Monitoring System: A bespoke solution centralizing ballast tank pressure data into one intuitive interface. The system also integrated Brosols’ motion sensor data and provides outputs for direct use in GHS software, providing vital input during refloat operations.
Outcome
The Yu Shou Qi Hang was safely refloated in September 2025 and subsequently towed to South Korea for dismantling. The integration of Brosols’ monitoring technology and survey expertise proved critical to the successful execution of this high-profile salvage.
“Brosols has proven to be a reliable and flexible partner, combining strong technical knowledge with a practical approach. Their expertise across multiple fields has added significant value to our operations.”
