Customer Case | Underwater Vehicle Assists Inspect Urban Underground Pipe Network

In October 2021, AoHI Underwater Vehicle was invited by the government of Yancheng City, Jiangsu Province, and went to the area with its underwater vehicle to carry out urban underground pipeline inspection work. Through the demonstration of live operation of the underwater vehicle on site, the detection of the designated test pipeline was successfully completed, which significantly improved the efficiency of engineering operations and laid a solid foundation for carrying out standardized and patterned operations.

FindROV C20, a small industrial-grade underwater vehicle from AOHI, was used in the operation. It has the advantages of miniaturization, low cost, high flexibility and so on, which is ideal for replacing difficult manual work in the inspection of urban pipelines. In view of the sewage pipeline dark, sundry, poor vision of the environmental characteristics. The C20 is equipped with a multi-channel optic system, integrated with a customized pipeline scanning imaging sonar and a two-dimensional section imaging sonar to effectively face the complex environment inside the pipeline.

At a road in Yancheng, the FindROV underwater vehicle enters the pipeline through the wellhead, perfectly adapting to the urban pipeline work environment.1-2 engineers can be quickly deployed to carry out urban pipeline network operations.

When encountering pipeline deposits, we can visualize the undulating changes of the deposits and the length of the deposits from the images of the 2D sonar, we can also observe the siltation on the whole pipeline cross-section from the cross-sectional sonar.

During this engineering mission, the operators found some unescaped air still remaining above several sections of the underwater pipeline through anomalous images from the pipeline sonar, and did not find any damage to the pipeline.

The successful completion of this urban underground pipeline inspection task in Yancheng marks that this urban full water pipeline inspection robot system, which is composed of FindROV C20 as the main body, configured with multi-channel vision and light system and equipped with customized professional-grade pipeline scanning sonar and imaging sonar, has been verified in practice. In the future, in this application field, FindROV will continue to optimize the product and integrate the new AI intelligent inspection technology to make the urban pipe network inspection more intelligent, efficient and economical!


Academician praises – Aohai subsea vehicle works in tandem with Arctic OBS seismometer

​In April 2021, Aohai’s underwater robotics staff took the Find series of underwater robots to Qiandao Lake for a collaborative exercise with the Ministry of Natural Resources’ Institute of Oceanography II on polar marine equipment.

The objective of the exercise was a simulated recovery operation of the Arctic OBS seismometer.

After a brief introduction by Aohai’s technical staff, Academician Li Jiabiao, Director of the Second Institute of Oceanography, Ministry of Natural Resources, personally operated the Aohai FindROV underwater robot and, in just over ten minutes, used the robot to clamp the floating ball tether and manoeuvre it to the designated position, where it was retrieved by the research staff to the deck, successfully completing the recovery exercise.

The manoeuvre was successfully completed by using a robot to hold the float tether and manoeuvre it to the designated position for retrieval to the deck by the research staff.

Academician Li said that underwater robots enrich the means of marine operations and help improve operational efficiency, which can be boldly tried. We hope that the Aohai underwater robots will continue to work hard to help the cause of China’s oceanic polar scientific research!

Aquatic Rescue | AOHI technical team travels to Wenzhou to conduct ROV training for Sea Eagle rescue team

​On 7 September 2020, the AOHI technical team went to Wenzhou to train the Sea Eagle rescue team on ROVs so that they can make a big difference in search and rescue.

Technicians instructed the Sea Eagles rescue team on the connection and handling of the ROV by practising the operation of the ROV in shallow waters.

A robotic gripping exercise was then carried out in deeper water to pick up the discarded ‘yellow bikes’.

This gives us a glimpse into the future of search and rescue activities with the AOHI Underwater Vehicle working underwater. The use of ROVs to search for and recover lost and sunken objects not only reduces the workload of rescuers, but also greatly improves the efficiency and safety of underwater search and rescue work.
