The working construction area was 45 meters, and the sea state was class 2 when the equipment entered the water, and gradually increased to class 5 as the day got darker during the working process.The “Haitun” accomplished the following tasks outstandingly. The main tasks are as follows: 

1.Using ROV observation and exploring the seabed environment before installation.

2.Real-time monitoring of the process of the suction bucket jacket entering the mud on the seabed.

3.After the installation, the underwater robot helped to monitor the salvage process to make sure the fiber optic cable was not entangled

The Haitun series of ROVs are light with powerful capabilities.The devices maximize movement and load capacity under the current size and weight, and can submerge underwater at a maximum depth of 1,000m.Equipped with eight high-performance electric thrusters,the forward ssspeed of the devices can reach3.5kn.The ROVs can be installed with sensors and tools for various uses.
