What role does ROV play at work?

Underwater operation refers to the construction theme activities carried out in the water. Before designing the water production system ,its design scheme underwater work tools, and special tools, it is necessary to have a holistic grasp of underwater operations, generally involving the following difficulties: What are the contents of underwater operations? What is the way to do the work on a daily assignment? What are the rules for doing this?

In general, ROVs are used for on-the-spot surveys, drilling support, installation support, operational support, inspection, maintenance and repair.

1 .Site survey:

Before carrying out the construction theme activities such as drilling and installation, it is necessary to carry out the water site survey in order to obtain the high-precision depth and geomorphological information content of the seabed.

If the sounding method is used to carry out more detailed seabed topographic map drawing, it can be completed by using underwater robots with depth gauge and acoustic recovery equipment; If you want to obtain a very accurate topographic map of the seafloor, it is necessary to use the multi-beam echo sound sink or side sweep sonar used by underwater robots to carry out a sweep, to obtain the characteristics of shallow geological structure, we must use a shallow profiler, which can assess the geological characteristics of the seabed in the basic scope of installation of water equipment.

2 .Drilling support.

In the whole process of all ROV drilling support, underwater observation (watching and acoustic observation) is the most critical work target, including deep-sea survey, monitoring the whole process of lifting of structures, application of mobile phone gyroscope, and inspection of bullseye correction equipment Structural perspective and the aspect ratio and its accurate measurement on completion. During the structural installation and inspection period, it is very likely that ROV or other special underwater remote control tools must be used to carry out some necessary work interventions.
